  • Best Geocoding Service for iPhone Developers

    - by ckrames1234
    I have made an app that gets an array of addresses from a web service and I want to map them. I know Apple left this out in MapKit, including only a reverse GeoCoder. I was wondering what the best way to approach this problem was. Web Service? Google Maps API (How do API keys work?)? CloudMade? What is your opinions on which service is fastest, easiest to use, and cheapest (hopefully free)? Thanks, Conrad Kramer

  • Possible to change the alpha value of certain pixels on iPhone?

    - by emi1faber
    Is it possible to change just a portion of a Sprite's alpha in response to user interaction? A good example of what I mean is iFog or iSteam, where the user can wipe "steam" off the iPhone's screen. Swapping images out wouldn't be feasible due to the sheer number of possibilities where the user could touch and move... For example, say you have a simple app that has a brick wall in the background that has graffiti on it, so there'd be two sprites, one of the brick wall, then one of the graffiti that has a higher z value than the brick wall. Then, based upon where the user touches (assuming their touch controls a sandblaster), some of the graffiti should be removed, but not all of it, which could be accomplished by changing the alpha value on a portion of the graffiti sprite. Is there any way to do this in cocos2d-iphone? Or, do I need to drop down into openGL, and if so, where would be a good place to start my search on how to accomplish this? Ideally, I'd like to accomplish this on a cocos2d-iphone Sprite, but if it's not possible, where's the best place to start looking? Thanks in advance, Ben

  • Best FTP Objective-C wrapper for iPhone

    - by jamone
    I know you use the C based networking API to do FTP communication but I'd prefer to use something a little higher level. I've seen a few Objective-C based wrappers but I'm not sure what to use. I don't need that complex of FTP interaction. Its just the typical create/delete dirs, upload/download files... What do you recommend?

  • Getting sectionNameKeyPath to work with CoreData/UITableViewController

    - by Elon
    In my AppDelegate I create an NSFetchedResultsController with sectionNameKeyPath set to @"group". In viewWillAppear in my TableViewController I performFetch, then call a method called findGroups. findGroups does some complicated analysis of the entire dataset to identify groups, then sets the "group" transient property on each object to the correct string value. I can see with NSLog that these are all set correctly and in coherent groups. But, tinker as I may, my cells are shown in a single section with the title of the first group. Any ideas?

  • HTTPHeaders Added to Downloaded File - CocoaHTTPServer???

    - by Don
    In an iPhone app where I use cocoahttpserver and take a sqlite database file from the iPhone and download it with a browser to my PC, when I look at the downloaded file using TextEdit, I see the text (below) at the end of the file. This text has apparently no effect on use of the database file, but I would prefer to not add stuff to the database file at all. Any ideas where this header info is coming from in cocoahttpserver and how to stop it? Thanks. ------WebKitFormBoundary3RAcT2SVGhGPnoA6 Content-Disposition: form-data; name="submit.x" 26 ------WebKitFormBoundary3RAcT2SVGhGPnoA6 Content-Disposition: form-data; name="submit.y" 12 ------WebKitFormBoundary001Quvx6Efgaf23y Content-Disposition: form-data; name="submit.x" 30 ------WebKitFormBoundary001Quvx6Efgaf23y Content-Disposition: form-data; name="submit.y" 12 ------WebKitFormBoundaryfHyUUs1p31kBJ3gA Content-Disposition: form-data; name="submit.x" 52 ------WebKitFormBoundaryfHyUUs1p31kBJ3gA Content-Disposition: form-data; name="submit.y" 9

  • iPhone UIControl and Subview

    - by Jack Thompson
    I currently have a UIControl, which has a number of subviews (image, label). Unfortunately when I use addTarget etc. It doesn't detect touches on the subviews. [myCustomView addTarget:self action:@selector(touchedView:) forControlEvents:UIControlEventTouchUpInside]; Is it possible for the UIControl to detect touches on subviews or should i be approaching it differently.

  • URL filtering for UIWebView on the iPhone

    - by Zac Altman
    Can someone please shed some light on how I would get this to work: http://www.icab.de/blog/2009/08/18/url-filtering-with-uiwebview-on-the-iphone/ I tried making the "FilteredWebCache.h" and "FilteredWebCache.m" files in my project, but it said that "FilterManager.h" did not exist. What am I meant to do with those files? This I put in viewDidLoad: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *docDir = [paths objectAtIndex:0]; NSString *path = docDir; // the path to the cache file NSUInteger discCapacity = 10*1024*1024; NSUInteger memoryCapacity = 512*1024; FilteredWebCache *cache = [[FilteredWebCache alloc] initWithMemoryCapacity:memoryCapacity diskCapacity:discCapacity diskPath:path]; [NSURLCache setSharedURLCache:cache]; [cache release];

  • iPhone: Issue disabling Auto-Cap/autocorrect on a UITextField

    - by phil swenson
    For some reason, even though I disable the auto-cap and auto-correct of my UITextField, it's still capitalizing the first letter of my input. Here is the code: UITextField* textField = [[[UITextField alloc] initWithFrame:CGRectMake(90.0, 10.0, 213.0, 25.0)] autorelease]; [textField setClearButtonMode:UITextFieldViewModeWhileEditing]; textField.returnKeyType = UIReturnKeyGo; textField.autocorrectionType = FALSE; textField.autocapitalizationType = UITextAutocapitalizationTypeNone; textField.delegate = self; if (inputFieldType == Email) { label.text = @"Email:"; textField.keyboardType = UIKeyboardTypeEmailAddress; emailTextField = textField; textField.placeholder = @"Email Address"; } else { // password textField.secureTextEntry = TRUE; label.text = @"Password:"; if (inputFieldType == Password){ textField.placeholder = @"Password"; passwordTextField = textField; } if (inputFieldType == ConfirmPassword){ textField.placeholder = @"Confirm Password"; confirmPasswordTextField = textField; } } See screenshot:

  • Clear UIWebView content upon dismissal of modal view (iPhone OS 3.0)

    - by Ricky
    I currently have a UIWebView that is displayed within a modal view. It is basically a detail view that provides a view of a page when the user clicks a link. When the view is dismissed and then brought up again (when the user clicks another link), the previously-loaded content is still visible and the new content loads "on top" of the last content. This makes sense because the instance of the UIWebView persists between sessions and is only released when the memory is needed. However, I would like to completely clear the UIWebView when the modal view is dismissed so that 1) content is cleared and 2) memory is freed. Thus far my research and attempts have not found an answer. These links haven't worked for me: http://stackoverflow.com/questions/2184688/is-it-possible-to-free-memory-of-uiwebview http://stackoverflow.com/questions/2311564/reused-uiwebview-showing-previous-loaded-content-for-a-brief-second-on-iphone I've tried [[NSURLCache sharedURLCache] removeAllCachedResponses]; and setting the webView to nil and manually releasing the webView upon modal-view-dismiss to no avail. Any thoughts from the wizened masses?

  • How to handle correctly HTTP Digest Authentication on iPhone

    - by Fabiano Francesconi
    Hello guys. I'm trying to upload a file onto my personal server. I've written a small php page that works flawlessy so far. The little weird thing is the fact that I generate all the body of the HTTP message I'm going to send (let's say that amounts to ~4 mb) and then I send the request to my server. The server, then, asks for an HTTP challenge and my delegate connection:didReceiveAuthenticationChallenge:challenge replies to the server with the proper credentials and the data. But, what's happened? The data has been sent twice! In fact I've noticed that when I added the progressbar.. the apps sends the data (4mb), the server asks for authentication, the apps re-sends the data with the authentication (another 4mb). So, at the end, I've sent 8mb. That's wrong. I started googling and searching for a solution but I can't figure out how to fix this. The case scenarios are two (my guess): Share the realm for the whole session (a minimal HTTP request, then challenge, then data) Use the synchronized way to perform an HTTP connection (things that I do not want to do since it seems an ugly way to handle this kind of stuff to me) Thank you

  • Creating a common selector class with UITableView or UIPicker

    - by trevrosen
    I have several places in my app where I need to select a Foo for further processing from a list of Foo objects. I'd like to do this as a modal view, but neither UIPicker nor UITableView seems to lend itself to the standard approach, since the usual way to do a modal view controller involves setting the parent view controller up as the delegate, and both of those classes need to implement data source protocols, etc. Implementing the data source and selection protocol methods in my parent view controller defeats the purpose of trying to use one common class for implementing this modal selector screen all over my app. Does anyone have any solutions to this problem or am I effectively stuck implementing this selector class over and over again?

  • iPhone UISlider with two thumbs/indicators?

    - by ChrisW
    Is anyone aware of a version of the iPhone UISlider control with two thumbs? I need a control that will allow specifying a range of values. The UISlider API docs would imply this isn't possible with the standard control, so I was wondering if anyone had a solution for this (or had solved it themselves).

  • Why is my app delegate's didFinishLaunchingWithOptions method all of sudden being called AFTER my Ro

    - by BeachRunnerJoe
    Hi. I've been playing with the iPad's SplitView template in Xcode. Here are two of the many important methods that are auto-generated for you by the Split View-based Application template... AppNameAppDelegate.m #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after app launch rootViewController.managedObjectContext = self.managedObjectContext; // Add the split view controller's view to the window and display. [window addSubview:splitViewController.view]; [window makeKeyAndVisible]; return YES; } RootViewController.m #pragma mark - #pragma mark View lifecycle - (void)viewDidLoad { [super viewDidLoad]; self.clearsSelectionOnViewWillAppear = NO; self.contentSizeForViewInPopover = CGSizeMake(320.0, 600.0); NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } } When you build and run the project before making any changes at all, the application:didFinishLaunchingWithOptions method is called before the RootViewController:viewDidLoad method is called. I'm new to iPhone development, but I'm assuming this is the correct and typical sequence. However, as soon as I changed the RootViewController code and set it as a subclass of UIViewController (instead of UITableViewController by default), and made the respective adjustments in Interface Builder, suddenly the RootViewController:viewDidLoad is being called before the application:didFinishLaunchingWithOptions method. I need to get it back to the way it was working before because, as you can see in the code, the viewDidLoad method depends on didFinishLauchingWithOptions method to execute so it can set the rootViewController's managedObjectContext that it uses to perform the fetch request. Any ideas what caused this? Any ideas how I can fix this? Thanks so much in advance for your help! I'm gonna keep researching and playing with the code.

  • How to upload images from iPhone app developed using Titanium

    - by Karthik.K
    Hi, I finally landed up in developing an iPhone app using Titanium Mobile. Now the problem I face is, Im able to run the app, and the app also sends the image to the server. But Im not able to see the file that got uploaded to the server. I have pasted the iPhone app's code to send image to the server and also, the PHP file that would receive the file from the app. var win = Titanium.UI.currentWindow; var ind=Titanium.UI.createProgressBar({ width:200, height:50, min:0, max:1, value:0, style:Titanium.UI.iPhone.ProgressBarStyle.PLAIN, top:10, message:'Uploading Image', font:{fontSize:12, fontWeight:'bold'}, color:'#888' }); win.add(ind); ind.show(); Titanium.Media.openPhotoGallery({ success:function(event) { Ti.API.info("success! event: " + JSON.stringify(event)); var image = event.media; var xhr = Titanium.Network.createHTTPClient(); xhr.onerror = function(e) { Ti.API.info('IN ERROR ' + e.error); }; xhr.onload = function() { Ti.API.info('IN ONLOAD ' + this.status + ' readyState ' + this.readyState); }; xhr.onsendstream = function(e) { ind.value = e.progress ; Ti.API.info('ONSENDSTREAM - PROGRESS: ' + e.progress+' '+this.status+' '+this.readyState); }; // open the client xhr.open('POST','http://www.myserver.com/tmp/upload2.php'); xhr.setRequestHeader("Connection", "close"); // send the data xhr.send({media:image}); }, cancel:function() { }, error:function(error) { }, allowImageEditing:true }); And here is the PHP code on the server: http://www.pastie.org/891050 I'm not sure where I'm going wrong. Please help me out in this issue. Would love to provide if you need some more information.

  • UIImages not displaying in TableView on iPhone, but working in Simulator

    - by Graeme
    Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. It's just a blank white space. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }

  • onPause/onResume activity issues

    - by Josh
    I have a small test application I am working on which has a timer that updates a textview to countdown from 100 to 0. That works fine, but now I am trying to pause the application if the user presses the back button on the phone and then restart the timer from where they left off when they reopen the app. Here is the code I am using: @Override public void onPause() { if(this._timer_time_remaining > 0) { this.timer.cancel(); } super.onPause(); Log.v("Pausing", String.format("Pausing with %d", this._timer_time_remaining)); } @Override public void onResume() { super.onResume(); Log.v("Resuming", String.format("Resuming with %d", this._timer_time_remaining)); if(this._timer_time_remaining > 0) { setContentView(R.layout.in_game); start_timer(this._timer_time_remaining); } } The start_timer() method creates a CountDownTimer which updates the textview in the onTick method and updates the this._timer_time_remaining int variable. CountDownTimer and _timer_time_remaining are both declared at the class level like this: private CountDownTimer timer; private int _timer_time_remaining; From the Log.v() prints I see that the _timer_time_remaining variable has the correct number of seconds stored when onPause is called, but it is set back to 0 when onResume starts. Why does the variable get reset? I thought that the application would continue to run in the background with the same values. Am I missing something? This is all declared in a class that extends Activity. Thanks in advance!

  • TwitPic Multiple image upload

    Has anybody experienced Timeout error with TwitPic API using ASIFormDataRequest when uploading multiple images? Status updates without images are fine. I was trying to upload the exact same 2 images. The first request went through fine, but the second one was timeout. It also happens when multiple images are uploaded, some went through, but some didn't. It's happening randomly and I have no idea how to debug it anymore.
