• Partner Blog: Hub City Media Introduces iPad Application for Oracle Identity Analytics

  - by Tanu Sood

  About the Writer:Steve Giovannetti is CTO of Hub City Media, Inc., a company that specializes in implementation and product development on the Oracle Identity Management platform. Recently, Hub City Media announced the introduction of iPad application IdentityCert for Oracle Identity Analytics. This post explore the business use cases and application of IdentityCert.Hub City Media(HCM) has been deploying certification solutions based on Oracle Identity Analytics since it first appeared on the market as Vaau RBACx. With each deployment we've seen the same pattern repeat time and time again:1. Customers suffering under the weight of manual access certification regimens deploy Oracle Identity Analytics (OIA) for automated certification. 2. OIA improves the frequency, speed, accuracy, and participation of certifications across the organization. 3. Then the certifiers, typically managers and supervisors, ask, “Is there any easier way to do these certifications offline?”The current version of OIA has a way to export certification data to a spreadsheet.  For some customers, we've leveraged this feature and combined it with some of our own custom code to provide a solution based on spreadsheet exports and imports.  Customers export the certification to Microsoft Excel, complete it, and then import the spreadsheet to OIA. It worked well for offline certification, but if the user accidentally altered the format of the spreadsheet, the import of the data could fail. We were close to a solution but it wasn’t reliable.Over the past few years, we've seen the proliferation of Apple iOS devices, specifically the iPhone and iPad, in the enterprise.  As our customers were asking for offline certification, we noticed the same population of users traditionally responsible for access certification, were early adopters of the iPad. The environment seemed ideal for us to create an iPad application to support offline certifications using Oracle Identity Analytics. That’s why we created IdentityCert™.IdentityCert allows users to view their analytics dashboard, complete user certifications, and resolve policy violations with OIA, from their iPads.The current IdentityCert analytics dashboard displays the same charts that are available in the Oracle Identity Analytics product. However, we plan to expand the number of available analytics in future releases.The main function of IdentityCert is user certification which can be performed quickly and efficiently using a simple touch interface. Managers tap into a certification, use simple gestures to claim users and certify their access.  Certifications can be securely downloaded to IdentityCert and can be completed with or without a network connection. The user can upload the completed certifications once they are connected to a cellular or wi-fi network.Oracle Identity Analytics can generate policy violation notifications based on detective scans of identity warehouse or via preventative analysis of identity access requests. IdentityCert allows users to view all policy violations, resolve, or delegate them to appropriate users. IdentityCert also analyzes the policy violation expression and produces more human friendly descriptions of the policy violation which improves the ability of users to resolve the violation. IdentityCert can be deployed quickly into a customer's environment. It is deployed with Hub City Media's ID Services to connect Oracle Identity Analytics securely with the iPad application.Oracle Identity Management 11g R2 is an important evolutionary release. Oracle's Identity Management suite has more characteristics of a cohesive platform. This platform provides an integrated set of identity services that can be used to protect, manage, and audit security within the enterprise. At HCM we take the platform concept a step further and see it as an opportunity to create unique solutions for Oracle Identity Management customers. IdentityCert is our commitment to this platform. You can download IdentityCert from the Apple iOS App Store today. It includes a demo dataset that you can use to explore the functions of the product without any server infrastructure. Download it. Give it a try. We would appreciate your interest and welcome any feedback.Resources:Press Release: Hub City Media Introduces iPad Application IdentityCert™ for Oracle Identity AnalyticsApp Store Download: http://bit.ly/IdentityCertOracle Identity Governance Suite

• Oracle Retail Mobile Point-of-Service

  - by David Dorf

  When most people discuss mobile in retail, they immediately go to shopping applications.  While I agree the consumer side of mobile is huge, I believe its also important to arm store associates with mobile tools.  There are around a dozen major roll-outs of mobile POS to chain retailers, and all have been successful.  This does not, however, signal the demise of traditional registers.  Retailers will adopt mobile POS slowly and reduce the number of fixed registers over time, but there's likely to be a combination of both for the foreseeable future.  Even Apple retains at least one fixed register in every store, you just have to know where to look. The business benefits for mobile POS are pretty straightforward: 1. Faster checkout.  Walmart's CFO recently reported that for every second they shave off the average transaction time, they can potentially save $12M a year in labor.  I think its more likely that labor will be redeployed to enhance the customer experience. 2. Smarter associates.  The sales associates on the floor need the same access to information that consumers have, if not more.  They need ready access to product details, reviews, inventory, etc. to meet consumer expectations.  In a recent study, 40% of consumers said a savvy store associate can impact their final product selection more than a website. 3. Lower costs.  Mobile POS hardware (iPod touch + sled) costs about a fifth of fixed registers, not to mention the reclaimed space that can be used for product displays. But almost all Mobile POS solutions can claim those benefits equally.  Where there's differentiation is on the technical side.  Oracle recently announced availability of the Oracle Retail Mobile Point-of-Service, and it has three big technology advantages in the market: 1. Portable. We used a popular open-source component called PhoneGap that abstracts the app from the underlying OS and hardware so that iOS, Android, and other platforms could be supported.  Further, we used Web technologies such as HTML5 and JavaScript, which are commonly known by many programmers, as opposed to ObjectiveC which is more difficult to find.  The screen can adjust to different form-factors and sizes, just like you see with browsers.  In the future when a new, zippy device gets released, retailers will have the option to move to that device more easily than if they used a native app. 2. Flexible.  Our Mobile POS is free with the Oracle Retail Point-of-Service product.  Retailers can use any combination of fixed and mobile registers, and those ratios can change as required.  Perhaps start with 1 mobile and 4 fixed per store, then transition over time to 4 mobile and 1 fixed without any additional software licenses.  Our scalable solution supports lots of combinations. 3. Consistent.  Because our Mobile POS is fully integrated to our traditional POS, the same business logic is reused.  Third-party Mobile POS solutions often handle pricing, promotions, and tax calculations separately leading to possible inconsistencies within the store.  That won't happen with Oracle's solution. For many retailers, Mobile POS can lower costs, increase customer service, and generally enhance a consumer's in-store experience.  Apple led the way, but lots of other retailers are discovering the many benefits of adding mobile capabilities in their stores.  Just be sure to examine both the business and technology benefits so you get the most value from your solution for the longest period of time.

• Can anybody help me in designing my UITableView into MVC Pattern ?

  - by user2877880

  I have written a ViewController in which i get data from the internet and display it in a UItableview using a json parser which uses object for key to identify its objects. What i would like your help in is to convert it into MVC pattern to make it less clumsy instead of including everything in the same controller class. Please try explaining it to me in terms of my code. THANKS IN ADVANCE. The code is as given below #import "ViewController.h" #import "AFNetworking.h" #import "ModelTableArray.h" @implementation ViewController @synthesize tableView = _tableView, activityIndicatorView = _activityIndicatorView, movies = _movies; - (void)viewDidLoad { [super viewDidLoad]; // Setting Up Table View self.tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, self.view.bounds.size.height) style:UITableViewStylePlain]; self.tableView.dataSource = self; self.tableView.delegate = self; self.tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; self.tableView.hidden = YES; [self.view addSubview:self.tableView]; // Setting Up Activity Indicator View self.activityIndicatorView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]; self.activityIndicatorView.hidesWhenStopped = YES; self.activityIndicatorView.center = self.view.center; [self.view addSubview:self.activityIndicatorView]; [self.activityIndicatorView startAnimating]; // Initializing Data Source self.movies = [[NSArray alloc] init]; NSURL *url = [[NSURL alloc] initWithString:@"http://itunes.apple.com/search?term=rocky&country=us&entity=movie"]; NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url]; UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:self action:@selector(refresh:) forControlEvents:UIControlEventValueChanged]; [self.tableView addSubview:refreshControl]; [refreshControl endRefreshing]; AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { self.movies = [JSON objectForKey:@"results"]; [self.activityIndicatorView stopAnimating]; [self.tableView setHidden:NO]; [self.tableView reloadData]; } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo); }]; [operation start]; } - (void)refresh:(UIRefreshControl *)sender { NSURL *url = [[NSURL alloc] initWithString:@"http://itunes.apple.com/search?term=rambo&country=us&entity=movie"]; NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url]; AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { self.movies = [JSON objectForKey:@"results"]; [self.activityIndicatorView stopAnimating]; [self.tableView setHidden:NO]; [self.tableView reloadData]; } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo); }]; [operation start]; [sender endRefreshing]; } - (void)viewDidUnload { [super viewDidUnload]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } // Table View Data Source Methods - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (self.movies && self.movies.count) { return self.movies.count; } else { return 0; } } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellID = @"Cell Identifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (!cell) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellID]; } NSDictionary *movie = [self.movies objectAtIndex:indexPath.row]; cell.textLabel.text = [movie objectForKey:@"trackName"]; cell.detailTextLabel.text = [movie objectForKey:@"artistName"]; NSURL *url = [[NSURL alloc] initWithString:[movie objectForKey:@"artworkUrl100"]]; [cell.imageView setImageWithURL:url placeholderImage:[UIImage imageNamed:@"placeholder"]]; return cell; } @end

• How does one get UI_USER_INTERFACE_IDIOM() to work with iPhone OS SDK < 3.2

  - by drootang

  Apple advises using the following code to detect whether running on an iPad or iPhone/iPod Touch: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { // The device is an iPad running iPhone 3.2 or later. // [for example, load appropriate iPad nib file] } else { // The device is an iPhone or iPod touch. // [for example, load appropriate iPhone nib file] } The problem is that UI_USER_INTERFACE_IDIOM() and UIUserInterfaceIdiomPad are NOT defined in the SDKs priory to 3.2. This seems to completely defeat the purpose of such a function. They can only be compiled and run on iPhone OS 3.2 (iPhone OS 3.2 can only be run on iPad). So if you can use UI_USER_INTERFACE_IDIOM(), the result will always be to indicate an iPad. If you include this code and target OS 3.1.3 (the most recent iPhone/iPod Touch OS) in order to test your iPhone-bound universal app code, you will get compiler errors since the symbols are not defined in 3.1.3 or earlier. If this is the recommended-by-Apple approach to runtime device-detection, what am I doing wrong? Has anyone succeeded using this approach to device-detection?

• image filters for iphone sdk development

  - by plsp

  Hi All, I am planning to develop an iphone app which makes use of image filters like blurring, sharpening,etc. I noticed that there are few approaches for this one, Use openGL ES. I even found an example code on apple iphone dev site. How easy is openGL for somebody who has never used it? Can the image filters be implemented using the openGL framework? There is a Quartz demo as well posted on apple iphone dev site. Has anybody used this framework for doing image processing? How is this approach compared to openGL framework? Don't use openGL and Quartz framework. Basically access the raw pixels from the image and do the manipulation myself. Make use of any custom built image processing libraries like this one. Do you know of any other libraries like this one? Can anybody provide insights/suggestions on which option is the best? Your opinions are highly appreciated. Thanks!

• Iphone page curl effect

  - by dragon

  I am using this code for Page curl effect ....Its work fine in simulator and device... But its not (setType:@"pageCurl") apple documented api , this caused it to be rejected by the iPhone Developer Program during the App Store review process: animation = [CATransition animation]; [animation setDelegate:self]; [animation setDuration:1.0f]; animation.startProgress = 0.5; animation.endProgress = 1; [animation setTimingFunction:UIViewAnimationCurveEaseInOut]; [animation setType:@"pageCurl"]; [animation setSubtype:@"fromRight"]; [animation setRemovedOnCompletion:NO]; [animation setFillMode: @"extended"]; [animation setRemovedOnCompletion: NO]; [[imageView layer] addAnimation:animation forKey:@"pageFlipAnimation"]; So i changed and using like this [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1]; [UIView setAnimationDelegate:self]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationWillStartSelector:@selector(transitionWillStart:finished:context:)]; [UIView setAnimationDidStopSelector:@selector(transitionDidStop:finished:context:)]; // other animation properties [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:imageView cache:YES]; // set view properties [UIView commitAnimations]; In this above code i want to stop the page curl effect at midway.. But i cant stop it in midway like map applications in ipod... Is this any fix for this? or Is there any apple documented methods used for page curl effect in ipod touch? I am searching lot. but didnt get any answer ? can anyone help me? Thanks in advance..plz

• UIImagePickerController in landscape on iPhone OS >= 3.2

  - by Mike

  Here is the problem. I have to open the UIImagePickerController in landscape. At this phase I am doing the app for iPhone but it will be soon adjusted for iPad. The classical way to force the UIImagePickerController to open in landscape would be to use this solution. But this solution has a problem, specially for iPad, that is the line, [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight]; because Apple rejects an application for doing that, as they don't want you to set an orientation, because if the user is holding the iPad on landscapeLeft the controller will appear upside down. Apple want you to use your paranormal powers and open the controller the right way for the user. The only problem is this: My controller is to appear when the application starts At this time, the orientation information is not yet available, because it takes a while for the device to discover its orientation; I've tried to get around this using the accelerometer to discover the orientation, but the accelerometer data is not yet available too when the app starts. I could make a routine to delay the application until the orientation is available, showing a black screen to the user in the mean time, or a beach ball, but I wonder if there's a more elegant way to do that! thanks.

• Retrieve GWT radiobutton value in servlet

  - by Florian d'Erfurth

  Hi, I'm having a headache figuring how to retrieve the gwt Radio Buttons values in the server side. Here is my UiBinder form: <g:FormPanel ui:field="form"><g:VerticalPanel ui:field="fruitPanel"> <g:RadioButton name="fruit">apple</g:RadioButton> <g:RadioButton name="fruit">banana</g:RadioButton> <g:SubmitButton>Submit</g:SubmitButton> ... Here is how i initialize the form: form.setAction("/submit"); form.setMethod(FormPanel.METHOD_POST); So i though i would have to do this on the servlet: fruit = req.getParameter("fruit") But of course this doesn't work, parameter fruit doesn't exist :/ Edit: Ok i get parameter fruit but it's always "on" I also did try to add the radio button in java with: RadioButton rb0 = new RadioButton("fruit", "apple"); RadioButton rb1 = new RadioButton("fruit", "banana"); fruitPanel.add(rb0); fruitPanel.add(rb1); So how should i do?

• UIView using Quartz rendering engine to display PDF has poor quality compared to original.

  - by Josh Kerr

  I'm using the quartz rendering engine to display a PDF file on the iphone using the 3.0 SDK. The result is a bit blurry compared to a PDF being shown in a UIWebView. How can I improve the quality in the UIView so that I don't need to rewrite my app to use the UIWebView. I'm using pretty much close to the example code that Apple provides. Here is some of my sample code: CGContextRef gc = UIGraphicsGetCurrentContext(); CGContextSaveGState(gc); CGContextTranslateCTM(gc, 0.0, rect.size.height); CGContextScaleCTM(gc, 1.0, -1.0); CGAffineTransform m = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, rect, 0, false); CGContextConcatCTM(gc, m); CGContextSetGrayFillColor(gc, 1.0, 1.0); CGContextFillRect(gc, rect); CGContextDrawPDFPage(gc, page); CGContextRestoreGState(gc); Apple's tutorial code actually results in a blurry PDF view as well. If you drop the same PDF into a UIWebView you'll see it is actually sharper. Anyone have any ideas? This one issue is holding a two year development project from launching. :(

• Generate JSON object with transactionReceipt

  - by Carlos

  Hi, I've been the past days trying to test my first in-app purchse iphone application. Unfortunately I can't find the way to talk to iTunes server to verify the transactionReceipt. Because it's my first try with this technology I chose to verify the receipt directly from the iPhone instead using server support. But after trying to send the POST request with a JSON onbject created using the JSON api from google code, itunes always returns a strange response (instead the "status = 0" string I wait for). Here's the code that I use to verify the receipt: - (void)recordTransaction:(SKPaymentTransaction *)transaction { NSString *receiptStr = [[NSString alloc] initWithData:transaction.transactionReceipt encoding:NSUTF8StringEncoding]; NSDictionary *jsonDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"algo mas",@"receipt-data",nil]; NSString *jsonString = [jsonDictionary JSONRepresentation]; NSLog(@"string to send: %@",jsonString); NSLog(@"JSON Created"); urlData = [[NSMutableData data] retain]; //NSURL *sandboxStoreURL = [[NSURL alloc] initWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"will create connection"); [[NSURLConnection alloc] initWithRequest:request delegate:self]; } maybe I'm forgetting something in the request's headers but I think that the problem is in the method I use to create the JSON object. HEre's how the JSON object looks like before I add it to the HTTPBody : string to send: {"receipt-data":"{\n\t\"signature\" = \"AUYMbhY ........... D0gIjEuMCI7Cn0=\";\n\t\"pod\" = \"100\";\n\t\"signing-status\" = \"0\";\n}"} The responses I've got: complete response { exception = "java.lang.IllegalArgumentException: Property list parsing failed while attempting to read unquoted string. No allowable characters were found. At line number: 1, column: 0."; status = 21002; } Thanks a lot for your guidance.

• iPhone Keychain Questions

  - by AO

  Some questions: * Is there some way to view the data present in the iPhone keychain? * The items an application adds, cannot be accessed by any other application, can it? * What is the purpose of the identifier and access group in the initialization? My guess is that the identifier is simply used to find items but I'm a little bit unsure of the access group. If the access group is assigned nil, all applications can access the items? If the access group is assigned X, could the items be accessed by another application with the same string X as access group or what is the purpose of the access group in this case? * Is the data in the keychain removed when the application is removed? If not, how do I achieve that? And finally: I can't get the KeychainItemWrapper (Apple example) to work. I've added the KeychainItemWrapper files to my project and when running it on the phone, an exception is thrown by SecItemAdd, saying that one or more parameters were not valid (result code -50). The code triggering the SecItemAdd follows: KeychainItemWrapper* wrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"something" accessGroup:@"com.company.whatever"]; [wrapper setObject:@"this is my password" forKey:@"password"]; NSLog(@"Password: %@", [wrapper objectForKey:@"password"]); The code can be found at http://developer.apple.com/iphone/library/samplecode/GenericKeychain/index.html

• Opening a LWJGL window from a SWT app on Mac

  - by TomA

  I have a SWT app that opens a OpenGL window (using the LWJGL library) after a button is pressed. Works fine on Windows. On Mac, I get this error: 2010-03-05 02:28:25.315 java[1315:a07] [Java CocoaComponent compatibility mode]: Enabled 2010-03-05 02:28:25.316 java[1315:a07] [Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.100000 2010-03-05 02:28:25.317 java[1315:a07] Apple AWT Startup Exception : _createMenuRef called with existing principal MenuRef already associated with menu 2010-03-05 02:28:25.318 java[1315:a07] Apple AWT Restarting Native Event Thread The SWT window closes and then the app hangs, with no windows open. It looks like the SWT app doesn't shut down cleanly and leaves it's menu entries associated with it, which prevents the LWJGL window from opening. Mac OS X only wants one application menu. SWT doesn't free it's own menu and LWJGL wants to add another. Facts: A button in the SWT dialog is supposed to close the dialog and open a LWJGL window (org.lwjgl.opengl.Display). The button sets a static variable in the app to tell it what to do next after the SWT window is closed, so the LWJGL window is NOT being opened from a SWT callback directly. The button then closes the SWT window. I don't know the correct way of doing this but tried various combinations of shell.close, shell.dispose, display.close and display.dispose, none of them worked. They all close the window but the error occurs every time. Does anyone know what could be done to make this work?

• How can an iPhone access another non-iPhone device over wireless or bluetooth?

  - by Tai Squared

  I'm trying to figure out if an iPhone can connect to another non-iPhone device over wireless or bluetooth and have seen conflicting information. Much of what I've found was before version 3.0 of the SDK came out, when it certainly wasn't possible. Looking at questions like this mention you can't connect to an arbitrary device unless if it's part of the "Works for iPhone" device. Do I need hardware that is part of this program? Looking through the Apple documentation, it mentions connecting two iPhones, not an iPhone to another Bluetooth device. Then there are articles like this that includes this quote ...and with the newly-announced "standard support" should allow file transfer between the iPhone and a computer, as well as between nearby iPhones Other questions mention Bonjour, and the Apple documentation talk about connecting to Bonjour devices, but can an iPhone connect to any Bonjour device? Does it have to have a wifi connection, or can it use Bluetooth? Even if I could use Bluetooth to connect to another device, it won't be available on first generation iPhones and iTouches, I believe. Is that correct? I'm thinking of an iPhone application that would need to communicate with other non-iPhone devices in the area, probably using Bluetooth, but possibly a direct wireless connection. What are the possibilities and limitations of this approach? Is it not possible to have an iPhone connect to an arbitrary Bluetooth device? Does the other device have to be on a wireless Bonjour network that? I'm trying to figure out if it's even possible for this to work or if it's not worth the effort.

It's a regular state of affairs for me but specifically in this case I felt I could reach out to fellow stackoverflowers (that is, stackoverflow-ers, not stackover-flowers). uname -a Darwin macbookpro 10.3.0 Darwin Kernel Version 10.3.0: Fri Feb 26 11:58:09 PST 2010; root:xnu-1504.3.12~1/RELEASE_I386 i386 set bash-3.2$ set ... HOSTTYPE=x86_64 ... MACHTYPE=x86_64-apple-darwin10.0 ... I'm having a nightmare rebuilding some native ruby gems and I'm wondering whether this is part of the problem -- part of this machine says its 64 bit but another part 32 ... as far as I can tell? Under 'About this Mac' it says 'Intel Core 2 Duo' which Apple says is 64 bit. So why, after doing sudo gem pristine --all am I still getting this kind of error? dlopen(/Applications/Rails/ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.bundle, 9): no suitable image found. Did find: /Applications/Rails/ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.bundle: mach-o, but wrong architecture - /Applications/Rails/ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.bundle Specifically I had removed nokogiri and reinstalled it. No errors in output. bash-3.2$ sudo gem install nokogiri Building native extensions. This could take a while... Successfully installed nokogiri-1.4.2 1 gem installed thanks for any thoughts!

• Cannot find interface declaration for 'UIResponder'

  - by lfe-eo

  Hi all, I am running into this issue when trying to compile code for an iPhone app that I inherited from a previous developer. I've poked around on a couple forums and it seems like the culprit may be a circular #import somewhere. First - Is there any easy way to find if this is the case/find what files the loop is in? Second - Its definitely possible this isn't the problem. This is the full error (truncated file paths so its easier to view here): In file included from [...]/Frameworks/UIKit.framework/Headers/UIView.h:9, from [...]/Frameworks/UIKit.framework/Headers/UIActivityIndicatorView.h:8, from [...]/Frameworks/UIKit.framework/Headers/UIKit.h:11, from /Users/wbs/Documents/EINetIPhone/EINetIPhone_Prefix.pch:13: [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:15: error: expected ')' before 'UIResponder' [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:17: error: expected '{' before '-' token [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:42: warning: '@end' must appear in an @implementation context [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:51: error: expected ':' before ';' token [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:58: error: cannot find interface declaration for 'UIResponder' As you can see, there are other errors alongside this one. These seem to be simple syntax errors, however, they appear in one of Apple's UIKit files (not my own) so I am seriously doubting that Apple's code is truly producing these errors. I'm stumped as to how to solve this issue. If anyone has any ideas of things I could try or ways/places I could get more info on the problem, I'd really appreciate it. I'm very new to Obj-C and iPhone coding.

• Java 1.5 crypto on OS X - AccessControlException

  - by bpapa

  I'm trying to do a Google App Engine project on OS X (latest and greatest). I'm using classes from javax.crypto, and I'm seeing an AccessControlException thrown when I try to initialize an instance of the Mac class. Here's the stack trace: WARNING: Nested in java.lang.ExceptionInInitializerError: java.security.AccessControlException: access denied (java.lang.RuntimePermission loadLibrary.keychain) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264) at java.security.AccessController.checkPermission(AccessController.java:427) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkPermission(DevAppServerFactory.java:76) at java.lang.SecurityManager.checkLink(SecurityManager.java:818) at java.lang.Runtime.loadLibrary0(Runtime.java:816) at java.lang.System.loadLibrary(System.java:993) at com.apple.crypto.provider.HmacCore.<clinit>(HmacCore.java:26) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at java.lang.Class.newInstance0(Class.java:350) at java.lang.Class.newInstance(Class.java:303) at java.security.Provider$Service.newInstance(Provider.java:1130) at javax.crypto.Mac.a(DashoA12275) at javax.crypto.Mac.init(DashoA12275) Any ideas on 1 - what went wrong and how fix it 2 - if it's not fixable (I know Apple has not been the best supporter of Java in recent years), what's an alternative approach?

• iPhone: Fastest way to create a binary Plist with simple key/value strings

  - by randombits

  What's the best way to create a binary plist on the iPhone with simple string based key/value pairs? I need to create a plist with a list of recipe and ingredients. I then want to be able to read this into an NSDictionary so I can do something like NSString *ingredients = [recipes objectForKey:@"apple pie"]; I'm reading in an XML data file through an HTTP request and want to parse all of the key value pairs into the plist. The XML might look something like: <recipes> <recipe> <name>apple pie</name> <ingredients>apples and pie</ingredients> </recipe> <recipe> <name>cereal</name> <ingredients>milk and some other ingredients</ingredients> </recipe> </recipes> Ideally, I'll be able to write this to a plist at runtime, and then be able to read it and turn it into an NSDictionary later at runtime as well.

• Cocoa Bindings and Application Preferences - Crash

  - by iaefai

  Using the document provided by Apple to create an application preferences window that doesn't require any extra code, I seem to have triggered a crash that cannot be traced by me. While the stuff from Apple is older, I believe I have the settings pretty much the same as shown here: When I run my application (Hcode) and go to the preferences menu item, it brings up the proper window with the defaults I specified in the bindings with the exception of the Spaces per tab is blank (no idea how to fix this). When the window is closed, the application crashes with a backtrace similar to this: (gdb) bt #0 0x00007fff800cb1d4 in objc_msgSend_vtable5 () #1 0x00007fff80447cf3 in -[NSMenu _enableItem:] () #2 0x00007fff80447ad8 in -[NSCarbonMenuImpl _carbonUpdateStatusEvent:handlerCallRef:] () #3 0x00007fff8042b3b0 in NSSLMMenuEventHandler () #4 0x00007fff80e06b57 in DispatchEventToHandlers () #5 0x00007fff80e060a6 in SendEventToEventTargetInternal () #6 0x00007fff80e23d85 in SendEventToEventTarget () #7 0x00007fff80e52e61 in SendHICommandEvent () #8 0x00007fff80e66357 in UpdateHICommandStatusWithCachedEvent () #9 0x00007fff80e02a6d in HIApplication::EventHandler () #10 0x00007fff80e06b57 in DispatchEventToHandlers () #11 0x00007fff80e060a6 in SendEventToEventTargetInternal () #12 0x00007fff80e23d85 in SendEventToEventTarget () #13 0x00007fff80e6599b in SendMenuOpening () #14 0x00007fff80e65388 in DrawTheMenu () #15 0x00007fff80e65149 in MenuChanged () #16 0x00007fff80e643d4 in TrackMenuCommon () #17 0x00007fff80e60dbe in MenuSelectCore () #18 0x00007fff80e60596 in _HandleMenuSelection2 () #19 0x00007fff802fc3b9 in _NSHandleCarbonMenuEvent () #20 0x00007fff802cfeda in _DPSNextEvent () #21 0x00007fff802cf379 in -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] () #22 0x00007fff8029505b in -[NSApplication run] () #23 0x00007fff8028dd7c in NSApplicationMain () #24 0x0000000100001cac in main (argc=1, argv=0x7fff5fbff5e0) at /Users/iaefai/Projects/Hcode/Source/main.m:13 I am at a complete loss as to what the problem is. Is there potentially a better way of doing this?

• Is background tasks the solution for this problem?

  - by Trinca

  Hi. I need to develop an enterprise app that monitors the network traffic. Basically it detects if the user is in wi-fi or cellular data and save the amount of bytes was sent and received in a period of time. I saw an App at the AppStore that do exactly this job. Detecting wi-fi or cellular data is quite simple using the Reachability Sample provided by Apple. My problem is to keep monitoring the bytes sent and received while the app is in background. As it is an enterprise App, I used UIBackgroundModes "voip" to avoid the app to be terminated. I also installed the setKeepAliveTimeout method and I'm able to see the logs each 10 minutes, BUT only for 10 seconds after the method runs. I mean, setKeepAliveTimeout brings my App to run a Timer for 10 seconds each 1o minutes. I'm thinking wether or not a task in background is the best solution for my problem. I'll appreciate any comments. EDIT: Ok guys. Thats the perfect way to do it. First of all you must read this: http://www.christian-fries.de/blog/files/tag-ios.html I tried this and it works really fine. All we need to do is to create a second thread detached from the main one. This way we have a continuos threading running forever. You must see the GCD docs at Apple's website also. Second thing you should consider for an enterprise App is to set it up as a voip App, this way iOS will put your App running even after a reboot. It's a special behavior iOS has to keep voip Apps running. Thats it guys. I hope it can help you.

• - (void)keyboardWasShown not called when switching to another UITextField

  - by Shawn

  I'm having a strange problem that I don't understand. I have a UIScrollView with several UITextField objects. When I switch to the view, I set the first UITextField as firstresponder, and the keyboardWasShown method gets called due to the UIKeyboardDidShowNotification that the view is registered for. The weird thing is, when I touch the next UITextField, the keyboardWasShown method is not called. I don't understand this, since Apple's documentation says "If your interface has multiple text fields, the user can tap between them to edit the values in each one. When that happens, however, the keyboard does not disappear but the system does still generate UIKeyboardDidShowNotification notifications each time editing begins in a new text field." My code I've copied directly from Apple's documentation as well, and it works properly, but it only gets called the first time. What am I missing? - (void)registerForKeyboardNotifications { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardDidShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasHidden:) name:UIKeyboardDidHideNotification object:nil]; } - (void)keyboardWasShown:(NSNotification *)aNotification { //if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; CGSize kbSize = [[info objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue].size; CGRect bkgndRect = activeField.superview.frame; bkgndRect.size.height += kbSize.height; [activeField.superview setFrame:bkgndRect]; [scrollView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y) animated:YES]; keyboardShown = YES; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; }

• EXC_BAD_ACCESS NSUrlConnection
