  • How to tell if you touched a CCLabel? (Cocos2d Question)

    - by RexOnRoids
    How to tell if you touched a CCLabel? The following code obviously does not work well enough because it only tests for point equality. Naturally touch point will not necessarily be equal to the position property of the CCLabel (CCNode). How to I tell if a Touch point has fallen within the "rectangle?" of the CCLabel? - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; self.myGraphManager.isSliding = NO; if(CGPointEqualToPoint(location, label1.position)){ NSLog(@"Label 1 Touched"); }else if(CGPointEqualToPoint(location, label2.position)){ NSLog(@"Label 2 Touched"); }else if(CGPointEqualToPoint(location, label3.position)){ NSLog(@"Label 3 Touched"); }else if(CGPointEqualToPoint(location, label4.position)){ NSLog(@"Label 4 Touched"); }else if(CGPointEqualToPoint(location, label5.position)){ NSLog(@"Label 5 Touched"); }else if(CGPointEqualToPoint(location, label6.position)){ NSLog(@"Label 6 Touched"); } NSLog(@"Touch Made!"); } }

  • Get information form WebPage.

    - by william-hu
    I want to set up an app which can get the information from a particular web page. Then i display the value which got from that page to the iPhone user. Detail:In the webpage on server ,there is the schedule for bus time. If the user input origin and terminus then show the user the time information(list on webpage) in a label. That's all. What i have finished is : Open the iphone app, input two value(origin and terminus) to UITextField. Send the URL to server. Get the page, and show in UIWebView. What my problem next is how should i get the information form that page into another two labels to give the user about the bus time. I have store data in my Array receiveData: self.receivedData = data; I am not clear the data i received is XML or what? And how should i pick-up the value i want. (should i save the value to property list and the read the value?) Thank you so much!

  • SIGABRT on any UIView touch

    - by bitcruncher
    Hi. I'm afraid no amount of Googling has been able to save my hyde on this. I seem to be getting SIGABRT error anytime I touch the screen of the phone, on any UIView. The debugger console posts this error before the SIGABRT: .... [310:207] *** -[UIView _exclusiveTouchView]: unrecognized selector sent to instance 0x14c0c0 .... [310:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView _exclusiveTouchView]: unrecognized selector sent to instance 0x14c0c0' (this is not my specific call to _exclusiveTouchView, of course.) I would gladly post some code, but the truth is I cannot find (or guess) where this problem may be coming from. This is not happening on any ONE UIView but on all the UIViews in my stack. I can summarize the display logic, though, perhaps that will shed some light. So the application is created and a UIWindow is alloc'd. A single viewcontroller is then alloc'd, which makes and adds its own blank self.view, to which the other UIViews, representing the different game states, are attached. Interestingly enough, this error is does NOT happen on the Simulator, but happens consistently on the device. And I should also mention that the application has yet to override/use any of the touchesBegan:/Ended:/Moved: etc... In other words, this error happens without these methods in the code. I'm really not understanding where this error is coming from... Any suggestions?

  • iPhone UI layout debugging

    - by Cruinh
    I have this chronic issue with iPhone UI development where views sometimes seem to appear on the screen in a location different than what is reported by their frame property. Here is what I am doing to try to debug the issue: UIView *currentView = self.view; while (currentView!=nil) { NSLog(@"frame: %f,%f,%f,%f", currentView.frame.origin.x, currentView.frame.origin.y, currentView.frame.size.width, currentView.frame.size.height); currentView = currentView.superview; } I expect this should show me the coordinates and size of each element up the hierarchy from the given view to the app's root UIWindow element, with the coordinates for each element relative to its parent. However, that does not seem to be the case. In my current situation, I have a UI I'm trying to debug where every other time I rotate the device, the whole UI shifts up or down 20 pixels, yet the code block above reports exactly the same numbers every time. I tried calling the above code after as much as a second delay, but that the numbers still come out the same each time. Does anyone know a better way to inspect the screen coordinates of UI elements? If I can detect when one is wrong, I can compensate for the problem when it appears.

  • How do I forward `<Ctrl>-<Tab>` in Konsole?

    - by M. Tibbits
    I want to use intelligent tabbing in Emacs in C++ mode, but I also want to be able to insert a tab character when necessary. From other posts, I gather that the easiest way is to bind <Ctrl>-<Tab> to indent. However, it appears that Konsole in KUbuntu won't forward the <Ctrl>? My current .emacs file contains: (defun my-c-mode-common-hook () (setq c++-tab-always-indent t) (setq tab-width 4) (setq indent-tabs-mode t) ) (add-hook 'c-mode-common-hook 'my-c-mode-common-hook) (global-set-key [C-tab] 'self-insert-command) So I believe that this will bind <Ctrl>-<Tab> to inserting a tab character. However, when I run: <Ctrl>-h k <Ctrl>-<Tab> Emacs only reports that I pressed the tab key. Is there some option to Konsole (which I have searched through to no avail) or global preferences in KUbuntu that I need to set so that the <Ctrl>- is also forwarded? (It certainly forwards all of the other <Ctrl>-blah commands.)

  • Python Post Upload JPEG to Server?

    - by iJames
    It seems like this answer has been provided a bunch of times but in all of it, I'm still getting errors from the server and I'm sure it has to do with my code. I've tried HTTP, and HTTPConnection from httplib and both create quite different terminal outputs in terms of formatting/encoding so I'm not sure where the problem lies. Does anything stand out here? Or is there just a better way? Pieced together from an ancient article because I really needed to understand the basis of creating the post: http://code.activestate.com/recipes/146306-http-client-to-post-using-multipartform-data/ Note, the jpeg is supposed to be "unformatted". The pseudocode: boundary = "somerandomsetofchars" BOUNDARY = '--' + boundary CRLF = '\r\n' fields = [('aspecialkey','thevalueofthekey')] files = [('Image.Data','mypicture.jpg','/users/home/me/mypicture.jpg')] bodylines = [] for (key, value) in fields: bodylines.append(BOUNDARY) bodylines.append('Content-Disposition: form-data; name="%s"' % key) bodylines.append('') bodylines.append(value) for (key, filename, fileloc) in files: bodylines.append(BOUNDARY) bodylines.append('Content-Disposition: form-data; name="%s"; filename="%s"' % (key, filename)) bodylines.append('Content-Type: %s' % self.get_content_type(fileloc)) bodylines.append('') bodylines.append(open(fileloc,'r').read()) bodylines.append(BOUNDARY + '--') bodylines.append('') #print bodylines content_type = 'multipart/form-data; boundary=%s' % BOUNDARY body = CRLF.join(bodylines) #conn = httplib.HTTP("www.ahost.com") # In both this and below, the file part was garbling the rest of the body?!? conn = httplib.HTTPConnection("www.ahost.com") conn.putrequest('POST', "/myuploadlocation/uploadimage") headers = { 'content-length': str(len(body)), 'Content-Type' : content_type, 'User-Agent' : 'myagent' } for headerkey in headers: conn.putheader(headerkey, headers[headerkey]) conn.endheaders() conn.send(body) response = conn.getresponse() result = response.read() responseheaders = response.getheaders() It's interesting in that the real code I've implemented seems to work and is getting back valid responses, but the problem it it's telling me that it can't find the image data. Maybe this is particular to the server, but I'm just trying to rule out that I'm not doing some thing exceptionally stupid here. Or perhaps there's other methodologies for doing this more efficiently. I've not tried poster yet because I want to make sure I'm formatting the POST correctly first. I figure I can upgrade to poster after it's working yes?

  • iPhone - Memory Management - Using Leaks tool and getting some bizarre readings.

    - by Robert
    Hey all, putting the finishing touches on a project of mine so I figured I would run through it and see if and where I had any memory leaks. Found and fixed most of them but there are a couple of things regarding the memory leaks and object alloc that I am confused about. 1) There are 2 memory leaks that do not show me as responsible. There are 8 leaks attributed to AudioToolbox with the function being RegisterEmbeddedAudioCodecs(). This accounts for about 1.5 kb of leaks. The other one is detected immediately when the app begins. Core Graphics is responsible with the extra info being open_handle_to_dylib_path. For the audio leak I have looked over my audio code and to me it seems ok. self.musicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:songFilePath] error:NULL]; [musicPlayer prepareToPlay]; [musicPlayer play] is called later on in a function. 2) Is it normal for there to be a spike in Object Allocation whenever a new view or controller is presented? My total memory usage is very, very low except for whenever I present a view controller. It spikes then immediately goes back down. I am guessing that this is just the phone handling all the information for switching or something. Blegh. Wall of text. Thanks in advance to anyone who helps! =)

  • WPF DataBinding to standard CLR properties in code-behind

    - by nukefusion
    Hi everyone, Just learning WPF databinding and have a gap in my understanding. I've seen a few similar questions on StackOverflow, but I'm still struggling in determining what I have done wrong. I have a simple Person class with a Firstname and Surname property (standard CLR properties). I also have a standard CLR property on my Window class that exposes an instance of Person. I've then got some XAML, with two methods of binding. The first works, the second doesn't. Can anybody help me to understand why the second method fails? There's no binding error message in the Output log. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300" DataContext="{Binding RelativeSource={RelativeSource Self}, Path=MyPerson}"> <StackPanel> <Label>My Person</Label> <WrapPanel> <Label>First Name:</Label> <Label Content="{Binding RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}, Path=MyPerson.FirstName}"></Label> </WrapPanel> <WrapPanel> <Label>Last Name:</Label> <Label Content="{Binding MyPerson.Surname}"></Label> </WrapPanel> </StackPanel> Edit: Ok, thanks so far. I've changed the second expression to: <Label Content="{Binding Surname}"></Label> I still can't get it to work though!

  • Use Lambda in Attribute constructor to get method's parameters

    - by Anthony Shaw
    I'm not even sure if this is possible, but I've exhausted all of my ideas trying to figure this out, so I figured I'd send this out to the community and see what you thought. And, if it's not possible, maybe you'd have some ideas as well. I'm trying to make an Attribute class that I can add to a method that would allow me to use a lambda expression to get each parameter of the method public ExampleAttribute : Attribute { public object Value { get; set; } public ExampleAttribute(--something here to make the lambda work--, object value) { Value = value; } } I'd like to be able to something like this below: [Example(x=x.Id, 4)] [Example(x=x.filter, "string value")] public ActionResult Index(int Id, string filter) { return View(); } I understand that I might be completely dreaming with this idea. I'm basically trying to write a model to allow for self-documenting REST API Documentation. In a recent project here at work we wrote a dozen or so services with 5 to 15 methods on each, I figure it's easier to write something to do this, than to hand code a documentation page for each. I would plan to eventually release this as an open-source project once I have it in a place that I feel it's releasable.

  • Anything speaking against the bitnami.org Ruby/Rails/Redmine Stack?

    - by Pekka
    I am looking to set up a Redmine server on a Windows virtual machine on my local workstation. (Background in this related question.) I have zero knowledge of Ruby nor Rails, and while Redmine may be the opportunity to dip into those platforms somewhat, my first goal is to get it running as quickly and easily as possible. For that, I am eyeing the Bitnami Redmine Package. It promises point-and-click install, and a self-contained environment with everything you need. Apart from the learning factor, are there any serious limitations this method implies? Any serious cutdowns in customizability? I will be wanting to customize the template right away, for example, and install plugins. The package looks o.k. to me but before I install it, I was curious to know whether anybody would advise against it and why. Edit: The first impression is great. From 0 to a working Redmine installation in twelve minutes! Wow.

  • What is a Windows scripting language that: does not rely on .NET and offers the most OOP support and

    - by jJack
    What is a Windows scripting language that: does not rely on .NET and offers the most OOP support and has simplest deployment? It doesn't necessarily need to be a scripting language; It can be in the form of a compiled executable, however it needs to be self contained--only ONE file, no DLL's and it cannot be declared to "include" other files. I cannot rely on the user having any .NET installed and it needs to be able to run on Windows 7 64 bit. By "most OOP support", I basically mean anything that has better OOP support than VBScript. A little context: Everything I have done thus far is in VBScript and writes a bunch of data into an .html file, which in the end is to be viewed by Internet Explorer. It also zips up a bunch of directories and files. It heavily relies on accessing the registry, file-system, and WMI (I can probably do without accessing WMI though, as long as I have good registry access). I can bring myself to code in any language so long as it meets me ridonkulous requirements stated above. I look forward to some good answers from those more experienced than I.

  • When is Facebook Connect supposed to call its delegate methods?

    - by RickiG
    Hi The Facebook connect code is eluding me a bit. I have no problem doing a login, and a wall post, however, I simply can not figure out how the delegate methods for the FBDialog andFBStreamDialog is supposed to work. - (void)postToWall { FBStreamDialog *dialog = [[[FBStreamDialog alloc] init] autorelease]; dialog.delegate = self; dialog.userMessagePrompt = @"Enter your message:"; dialog.attachment = [NSString stringWithFormat:@"JSONpost code"]; [dialog show]; } I adhere to these protocols in my controller: <FBDialogDelegate, FBSessionDelegate, FBRequestDelegate> I then implement the two methods: - (void) dialogDidCancel:(FBDialog *)dialog { NSLog(@"Failed"); } - (void) dialogDidSucceed:(FBDialog *)dialog { NSLog(@"Success"); } After I tap "publish" and the postToWall methods is done executing the Facebook "pop up" in the UI is empty, except a small "X" in the top right corner and a "F" (facebook logo) in the top left corner. The UI will stay there until I tap the "X", this results in the dialogDidCancel delegate method being called. The post data is showing up on the Facebook page, everything seems to work. Why is thedialogDidSucceedmethod never called? I need this to release my facebook controller and restore the UI back to where the user was before "starting" FB Connect. Thank You:)

  • Monitor web sites visited using Internet Explorer, Opera, Chrome, Firefox and Safari in Python

    - by Zachary Brown
    I am working on a project for work and have seemed to run into a small problem. The project is a similar program to Web Nanny, but branded to my client's company. It will have features such as website blocking by URL, keyword and web activity logs. I would also need it to be able to "pause" downloads until an acceptable username and password is entered. I found a script to monitor the URL visited in Internet Explorer (shown below), but it seems to slow the browser down considerably. I have not found any support or ideas onhow to implement this in other browsers. So, my questions are: 1). How to I monitor other browser activity / visited URLs? 2). How do I prevent downloading unless an acceptable username and password is entered? from win32com.client import Dispatch,WithEvents import time,threading,pythoncom,sys stopEvent=threading.Event() class EventSink(object): def OnNavigateComplete2(self,*args): print "complete",args stopEvent.set() def waitUntilReady(ie): if ie.ReadyState!=4: while 1: print "waiting" pythoncom.PumpWaitingMessages() stopEvent.wait(.2) if stopEvent.isSet() or ie.ReadyState==4: stopEvent.clear() break; time.clock() ie=Dispatch('InternetExplorer.Application',EventSink) ev=WithEvents(ie,EventSink) ie.Visible=1 ie.Navigate("http://www.google.com") waitUntilReady(ie) print "location",ie.LocationName ie.Navigate("http://www.aol.com") waitUntilReady(ie) print "location",ie.LocationName print ie.LocationName,time.clock() print ie.ReadyState

  • Alternatives to using web.config to store settings (for complex solutions)

    - by Brian MacKay
    In our web applications, we seperate our Data Access Layers out into their own projects. This creates some problems related to settings. Because the DAL will eventually need to be consumed from perhaps more than one application, web.config does not seem like a good place to keep the connection strings and some of the other DAL-related settings. To solve this, on some of our recent projects we introduced a third project just for settings. We put the setting in a system of .Setting files... With a simple wrapper, the ability to have different settings for various enviroments (Dev, QA, Staging, Production, etc) was easy to achieve. The only problem there is that the settings project (including the .Settings class) compiles into an assembly, so you can't change it without doing a build/deployment, and some of our customers want to be able to configure their projects without Visual Studio. So, is there a best practice for this? I have that sense that I'm reinventing the wheel. Some solutions such as storing settings in a fixed directory on the server in, say, our own XML format occurred to us. But again, I would rather avoid having to re-create encryption for sensitive values and so on. And I would rather keep the solution self-contained if possible. EDIT: The original question did not contain the really penetrating reason that we can't (I think) use web.config ... That puts a few (very good) answers out of context, my bad.

  • WPF validation red border doesn't show If UserControl collapsed first

    - by Creepy Gnome
    There seems to be a bug with WPF in 3.5, and I was hoping someone may have found a workaround. Basically if you have a custom UserControl that contains a TextBox and it is in a Window but initialized to be Collapsed by default in the xaml or code behind if it fails validation when you make the control visible it will not show the red border until it fails while visible. However, this works correctly when visibility is set to Hidden, just no when Collapsed. I am already overriding the ErrorTemplate with a style to workaround the Adornment issue with the red border staying visibile when you collapse the control. Below is my full style for the TextBox. If there is any additional changes or additions to make it work correctly with collapsed controls that would be great. <Style TargetType="TextBox"> <Setter Property="Margin" Value="3" /> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <ControlTemplate.Resources> <BooleanToVisibilityConverter x:Key="converter" /> </ControlTemplate.Resources> <DockPanel LastChildFill="True"> <Border BorderThickness="2" BorderBrush="Red" Visibility="{ Binding ElementName=placeholder, Mode=OneWay, Path=AdornedElement.IsVisible, Converter={StaticResource converter}}" > <AdornedElementPlaceholder x:Name="placeholder" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true" > <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}" /> </Trigger> </Style.Triggers> </Style>

  • Using the Apple Scripting bridge with Mail to send an attachment causes the message background to go

    - by Naym
    Hello, When I use the Apple Scripting Bridge to send a message with an attachment the background of the message is set to black which is a problem because the text is also black. The code in question is: MailApplication *mail = [SBApplication applicationWithBundleIdentifier:@"com.apple.Mail"]; /* create a new outgoing message object */ MailOutgoingMessage *emailMessage = [[[mail classForScriptingClass:@"outgoing message"] alloc] initWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: emailSubject, @"subject", [self composeEmailBody], @"content", nil]]; /* add the object to the mail app */ [[mail outgoingMessages] addObject: emailMessage]; /* set the sender, show the message */ emailMessage.sender = [NSString stringWithFormat:@"%@ <%@>",[[[mail accounts] objectAtIndex:playerOptions.mailAccount] fullName],[[[[mail accounts] objectAtIndex:playerOptions.mailAccount] emailAddresses] objectAtIndex:0]]; emailMessage.visible = YES; /* create a new recipient and add it to the recipients list */ MailToRecipient *theRecipient = [[[mail classForScriptingClass:@"to recipient"] alloc] initWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: opponentEmail, @"address", nil]]; [emailMessage.toRecipients addObject: theRecipient]; /* add an attachment, if one was specified */ if ( [playerInfo.gameFile length] > 0 ) { /* create an attachment object */ MailAttachment *theAttachment = [[[mail classForScriptingClass:@"attachment"] alloc] initWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: playerInfo.gameFile, @"fileName", nil]]; /* add it to the list of attachments */ [[emailMessage.content attachments] addObject: theAttachment]; } /* send the message */ [emailMessage send]; The actual change to the background colour occurs on the second last line, which is: [[emailMessage.content attachments] addObject: theAttachment]; The code sections above are essentially lifted from the SBSendMail example code from Apple. At this stage I've really only made the changes necessary to integrate with the data from my application. If I build and run the SBSendMail example after freshly downloading it from Apple the message background is also changed to black with execution of the same line. It does not appear to matter which type of file is attached, where it is located, or on which computer or operating system is used. This could be a bug in Apple's scripting bridge but has anyone come across this problem and found a solution? ALternatively does anyone know if the background colour of a MailOutgoingMessage instance can be changed with the scripting bridge? Thanks for any assistance with this, Naym.

  • [Cocoa] Binding CoreData Managed Object to NSTextFieldCell subclass

    - by ndg
    I have an NSTableView which has its first column set to contain a custom NSTextFieldCell. My custom NSTextFieldCell needs to allow the user to edit a "desc" property within my Managed Object but to also display an "info" string that it contains (which is not editable). To achieve this, I followed this tutorial. In a nutshell, the tutorial suggests editing your Managed Objects generated subclass to create and pass a dictionary of its contents to your NSTableColumn via bindings. This works well for read-only NSCell implementations, but I'm looking to subclass NSTextFieldCell to allow the user to edit the "desc" property of my Managed Object. To do this, I followed one of the articles comments, which suggests subclassing NSFormatter to explicitly state which Managed Object property you would like the NSTextFieldCell to edit. Here's the suggested implementation: @implementation TRTableDescFormatter - (BOOL)getObjectValue:(id *)anObject forString:(NSString *)string errorDescription:(NSString **)error { if (anObject != nil){ *anObject = [NSDictionary dictionaryWithObject:string forKey:@"desc"]; return YES; } return NO; } - (NSString *)stringForObjectValue:(id)anObject { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; return [anObject valueForKey:@"desc"]; } - (NSAttributedString*)attributedStringForObjectValue:(id)anObject withDefaultAttributes:(NSDictionary *)attrs { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; NSAttributedString *anAttributedString = [[NSAttributedString alloc] initWithString: [anObject valueForKey:@"desc"]]; return anAttributedString; } @end I assign the NSFormatter subclass to my cell in my NSTextFieldCell subclass, like so: - (void)awakeFromNib { TRTableDescFormatter *formatter = [[[TRTableDescFormatter alloc] init] autorelease]; [self setFormatter:formatter]; } This seems to work, but is extremely patch. On occasion, clicking to edit a row will cause its value to nullify. On other occasions, the value you enter on one row will populate other rows within the table. I've been doing a lot of reading on this subject and would really like to get to the bottom of this. What's more frustrating is that my NSTextFieldCell is rendering exactly how I would like it to. This editing issue is my last obstacle! If anyone can help, that would be greatly appreciated.

  • Cookie not renewing/overwriting in IE

    - by deceze
    I have a weird quirk with cookies in IE. When a user logs into the site, I'm generating a new session id and hence need to overwrite the cookie. The flow is basically: Client goes to https://secure.example.com/users/login page, automatically receiving a session id Client POSTs login credentials to same address Client receives the following headers together with a 302 redirect to https://secure.example.com/users/mypage: CAKEPHP=deleted; expires=Sun, 05-Apr-2009 04:50:35 GMT; path=/ CAKEPHP=98hnIO23...; expires=Mon, 12 Apr 2010 04:50:36 GMT; path=/; secure Client is supposed to visit https://secure.example.com/users/mypage, presenting the new session id. This works in all browsers, except IE (tested in 7 & 8). IE retains the old, unauthenticated session id, and is redirected back to the login page. It works on my local test environment (using a self-signed certificate at https://localhost:8443/...), but not on the live server. I'm using CakePHP and simply issue a $this->Session->renew(), which produces the above cookie headers. Any ideas how to get IE to accept the new cookie?

  • Debugging PHP Mail() and/or PHPMailer

    Hi, I'm quite stuck with a problem sending mail from a PHP script. Some data: Shared hosting, no SSH access, only hosting provider panel PHP version 5.2.5 Last year I built a site which had no problems sending mail with the same hosting Let's say the domain is “domain.com” and my private address is “[email protected]” for anonimity's sake in the following code.

  • What is the best anti-crack scheme for your trial or subscription software?

    - by gmatt
    Writing code takes time and effort and just like any other human being we need to live by making an income (save for the few that are actually self sustainable.) Here are 3 general schemes to make a living: Independent developers can offer a trial then purchase scheme. An alternative is an open source base application with pay extensions. A last (probably least popular with customers) scheme is to enforce some kind of subscription. Then the price of the software pales in comparison to the long term subscription fees. So, my question would be a hypothetical one. Suppose that you invest thousands of hours into developing an application. Now suppose you can choose any one of the three options to make a living off this application--or any other option you want--and suppose you have a very real fear of loosing 80% of your revenue to a cracked version if one can be made. To be clear this application does not require the internet to perform all its useful functions, that is, your application is a prime candidate to be a cracked release on some website. Which option would you feel most comfortable with defending yourself against this possible situation and briefly describe why this option would be the best.

  • Problem with TTWebController… alternative view controller template for UIWebView?

    - by prendio2
    I have a UIWebView with content populated from a Last.fm API call. This content contains links, many of which are handled by parsing info from the URL in: - (BOOL)webView:(UIWebView *)aWbView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType; …and passing that info on to appropraite view controllers. When I cannot handle a URL I would like to push a new view controller on the stack and load the webpage into a UIWebView there. The TTWebController in Three20 looks very promising since it has also implemented a navigation toolbar, loading indicators etc. Somewhat naively perhaps I thought I would be able to use this controller to display web content in my app, without implementing Three20 throughout the app. I followed the instructions on github to add Three20 to my project and added the following code to deal with URLs in shouldStartLoadWithRequest: TTWebController* browser = [[TTWebController alloc]init]; [browser openURL:@"http://three20.info"]; //initially test with this URL [self.navigationController pushViewController:navigator animated:YES]; This crashes my app however with the following notice: *** -[TTNavigator setParentViewController:]: unrecognized selector sent to instance 0x3d5db70 What else do I need to do to implement the TTWebController in my app? Or do you know of an alternative view controller template that I can use instead of the Three20 implementation?

  • How do I reliably get the size of my iPhone view taking rotations into consideration?

    - by Sebastian Celis
    My application uses a UITabBarController, multiple UINavigationControllers, and supports autorotation. In order to properly layout the subviews within each UIViewController's main view, I really need to know the size available to the UIViewContoller. I need this size to take the UINavigationBar, the UITabBar, and the status bar all into account, and thus only return the size available to the content view. I thought for sure I could use the following from within the UIViewController's code: CGRect viewControllerBounds = [[self view] bounds]; However, there are a couple of issues with this approach: The first time the view is loaded, viewControllerBounds reports the view as being 320 pixels wide by 460 pixels tall. This is wrong. With a status bar and a navigation bar showing, the height should only be 416 pixels. However, if I rotate the simulator to landscape and then rotate back, the height of viewControllerBounds changes to 416. If I rotate the first view in the navigation controller to landscape mode and then push another view controller onto the stack, viewControllerBounds for the new view reports a width of 300 pixels and a height of 480 pixels. So the view's bounds didn't even take the rotation into account. Is there a better way to do this? I really don't want to have to start hardcoding the widths and heights of all the various UI elements the iPhone OS provides. I have tried setting the autoresizing mask of the UIViewController's view, but that doesn't seem to change anything. The views definitely seem to be displaying properly. When I set a background color that view looks like it takes up all of the space available to it. Any pointers would be greatly appreciated.

  • How can I implement a volume meter for a song currently playing? (iPhone OS 3.1.3)

    - by Adam
    Hi i'm very new to core audio and I just would like some help in coding up a little volume meter for whatever's being outputted through headphones or built-in speaker. Like a dB meter. I have the following code, and have been trying to go through the apple source project "SpeakHere", but it's a nightmare trying to go through all that, without knowing how it works first... Could anyone shed some light? Here's the code I have so far... (void)displayWaveForm { while (musicIsPlaying == YES { NSLog(@"%f",sizeof(AudioQueueLevelMeterState)); } } (IBAction)playMusic { if (musicIsPlaying == NO) { NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/track7.wav",[[NSBundle mainBundle] resourcePath]]]; NSError *error; music = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; music.numberOfLoops = -1; music.volume = 0.5; [music play]; musicIsPlaying = YES; [self displayWaveForm]; } else { [music pause]; musicIsPlaying = NO; } }
