  • Universal iPhone/iPad application debug compilation error for iPhone testing

    - by andybee
    I have written an iPhone and iPad universal app which runs fine in the iPad simulator on Xcode, but I would now like to test the iPhone functionality. I seem unable to run the iPhone simulator with this code as it always defaults to the iPad? Instead I tried to run on the device and as it begins to run I get the following error: dyld: Symbol not found: _OBJC_CLASS_$_UISplitViewController Referenced from: /var/mobile/Applications/9770ACFA-0B88-41D4-AF56-77B66B324640/Test.app/Test Expected in: /System/Library/Frameworks/UIKit.framework/UIKit in /var/mobile/Applications/9770ACFA-0B88-41D4-AF56-77B66B324640/Test.app/TEST As the App is built programmatically rather than using XIB's, I've split the 2 device logics using the following lines in the main.m method: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate_Pad"); } else { retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate_Phone"); } From that point forth they use different AppDelegates and I've checked my headers to ensure the UISplitView is never used nor imported via the Phone logic. How do I avoid this error and is there a better way to split the universal logic paths in this programmatically-created app?

  • iPhone Simulator locks up immediately upon Build / Run

    - by Steve
    I'm having a problem getting my MacBook set up to build iPhone *apps* in xCode. The iPhone Simulator locks up and shows the "spinning circle" busy icon. I've tried everything I can think of, including resetting the simulator tried all of the different hardware options tried the two debug build choices in xCode. uninstalling the SDK and completely reinstalling I downloaded the SDK today - "xcode_3.2.2_and_iphone_sdk_3.2_final" I'm just upgraded from Leopard to Snow Leopard (10.6.3). I've run all the software updates. xCode version says 3.2.2 (1650) If it matters, my MacBook is 3-4 years old, 13 inch, dual 2.16 ghz intel cores, 2 gig RAM. I've never had a single problem with it. I would be so grateful if anyone can help me thanks so much,

  • Universal iPhone/iPad Windows-based app with Core Data crashes on iPhone SDK 4 beta 3

    - by Tarfa
    Hi all. I installed iPhone OS 4.0 Beta 3. When I create a new Windows-based universal app with Core Data (File New Project Windows-based Application --- select Universal in drop down and check the "Use Core Data for storage" check box) the app launches fine into the iPhone simulator but crashes in the iPad simulator. The console message returned is: dyld: Symbol not found: _OBJC_CLASS_$_NSURL Referenced from: /Users/tarfa/Library/Application Support/iPhone Simulator/3.2/Applications/5BB644DC-9370-4894-8884-BAEBA64D9ED0/Universal.app/Universal Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation I'm stumped. Anyone else experiencing this problem?

  • Starting Game dev on iPhone:iPad - learning path ??

    - by Tibi
    Hi there, I'm beginning in iPhone/iPad game dev and I'm searching to set up my learning path. The basic features I would like to learn (after the basic SDK iphone components programming) are : using a board like interface where I can move pawn with my fingers detect where the pawn was moved and triggers events in the game The board will be constitute by 6 tiles that may be organised randomly when starting the game : may i use an sdk component with a delegate and datasource to determine where the pawn was left and on which tile ? need to use dices (which kind of library may I use ?) ... Do you have any idea about where to start ? ;-) Many thanks, Tib.

  • MKMapKit custom annotations being added to map, but are not visible on the map

    - by culov
    I learned a lot from the screencast at http://icodeblog.com/2009/12/21/introduction-to-mapkit-in-iphone-os-3-0/ , and ive been trying to incorporate the way he creates a custom annotation into my iphone app. He is hardcoding annotations and adding them individually to the map, whereas i want to add them from my data source. So i have an array of objects with a lat and a lng (ive checked that the values are within range and ought to be appearing on the map) that i iterate through and do [mapView addAnnotation:truck] once this process is completed, i check the number of annotations on the map with [[mapView annotations] count] and its equal to the number it ought to be, so all the annotations are getting added onto the mapView, but for some reason I cant see any annotations in the simulator. I've compared my code with his in all the pertinent places many times, but nothing seems to stand out as being incorrect. Ive also reviewed my code for the last several hours trying to find a point where I do something wrong, but nothing is coming to mind. The images are named just as they are assigned in the custom AnnotationView, the loadAnnotation function is done properly, etc... i dont know what it could be. so i suppose if i could have the answer to one question it would be, what are possible causes for a mapView to contain several annotations, but to not show any on the map? Thanks

  • Why doesn't Apple make private APIs inaccessible?

    - by Howiecamp
    If Apple doesn't want developers using private APIs in the iPhone SDK, why don't they do something like mark the classes and/or methods with whatever the Objective-C equivalent of C#'s "internal" keyword? If the APIs are spread amongst multiple binaries, Apple could refactor them into dedicated private-API-only binaries to make this easier for them.

  • App not installed...because its resources have been modified

    - by brettr
    One user cannot install my app because they continue to receive the error: The application “myapp” was not installed on the iPhone “myPhone” because its resources have been modified I've read the error occurs because of adding files after the app is built. I have not added any files. Last week, the user could install the ad hoc without issue. Any ideas?

  • Adding a self-signed certificate to iphone Simulator?

    - by jr
    I have a self-signed certificate at the endpoint of my API. I'm trying to test some things using the simulator but am getting "untrusted server certificate". I have tried to use safari on the simulator to download the .crt file, but that doesn't seem to work. Where does iPhone Simulator get its keychain from? How can I add a trusted certificate so my application will work? UPDATE I got it to work by creating a CA and then adding a CA certificate using the iPhone provisioning tool. Then I was able to have a certificate signed by that CA certificate on the API server and the NSConnection just worked. I was not able to get it to work using a self-signed certificate for some reason. I need to re-attempt this using the provisioning software. My real question is how do I get this to work on the simulator? I would think that the simulator uses the keychain of the actual computer.

    Hi. I'm trying to get iPhone device token using following code - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; NSLog(@"Registering for push notifications..."); [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert]; } - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken { NSLog(@"Registered!@@"); } - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { NSLog(@"application:didFailToRegisterForRemoteNotificationsWithError: %@", error); if ([error code] != 3010) // 3010 is for the iPhone Simulator { // show some alert or otherwise handle the failure to register. } } but only getting "2010-04-02 18:23:35.434 Untitled[3133:207] Registering for push notifications..."

  • GameKit and GKPeerPicker on 1st Gen iPhone and iPod Touch

    - by Reese McLean
    This is my current set up for my multiplayer game: A view that gives connection tips and warns the user that multiplayer will not work on the 1st Gen iPhone or ipod Touch. There is a "connect" button that pushes the game view and starts the GKPeerPicker. Unfortunately, I don't have a 1st Gen iPhone or iPod Touch to test what happens if they press the connect button. The view will be pushed, but I don't know what will happen when the PeerPicker tries to show. So the Question(s): Is there anyway to tell if the user will not be able to use GameKit so that I can disable the "connect" button? What will happen if they do press the connect button and GameKit is not available?

  • iPhone: launch image for tab app?

    - by Karsten Silz
    I have a tab-based iPhone app where I want to increase the perceived start-up speed with a launch image. As defined by the iPhone HIG, the launch image is a screenshot of your app (called Default.png) that is displayed immediately and looks very similar to the app's first screen (e.g., the screenshot of an empty table when the app displays a table first). Now the problem with a tab-based app is that users can rearrange the order of tabs so that any of the tabs may be the first tab to show upon launch. I think I read somewhere that you can't change the Default.png programmatically in your app, but I couldn't find that in the HIG (and the "Clock" app seems to do exactly that - having one launch image per tab). So, how do provide a launch image for a tab-based app?

  • iphone settings disappear

    - by cagreen
    I have created an app which uses Application Settings and user defaults following the example in the book "Beginning iPhone Development". In some cases my settings seem to disappear. If I launch the simulator I can go into settings and see it, I can then open my app and my settings can be read from within the app. If I then leave my app and go back into the settings screen I can no longer see the settings for my app! I'm new to iPhone dev, is there something obvious that I'm overlooking? Thanks.

  • Facebook Source path issue in iPhone

    - by Arun Thakkar
    Hello everyone!! Hope You all are fie and also in one of your best of moods!! I need your help to solve an issue with Facebook. I have integrate Facebook Connect with my iPhone app. So as per step i have to write path of src folder into 'Header path info' Field in Project Build. I have given the absolute path to 'Header path info' Field. and its run fine without any Error.. But, Now When i Move the project folder to another destination, its but obvious, that path of src folder will change… So Now after moving file, when i run an application, It gives path error. So is there any way to solve this path issue? this comes when i run an app in simulator, and i guess It also won't run in iPhone because of problem of path of src folder. Kindly accept my Apologize if i have written anything wrong.. Looking Forwards, Thanks, Arun Thakkar

  • What are the Build Settings for a Universal iPhone and iPad Application

    - by McPragma
    What would be the settings to build and have accepted an universal app for both the iPad and iPhone? That is, what would be the settings in Project X Info Build for Architectures [ARCHS] ("Standard(armv6)" or "Optimized(armv6 armv7)" or other) Valid Architectures [VALID_ARCHS] ("armv6 armv7" or other) Build Active Architecture Only (checked or unchecked) and what would we select in the dropdown (Device - 3.2|Distribution|armv?) ? We're either getting warnings at build time that we haven't built for armv7, or the app upload is rejected on account of "The binary you uploaded was invalid. When supporting iPhone, the executable must include support for the armv6 architecture". Thank you for your help.

  • iPhone OpenGL ES freezes for no reason

    - by KJ
    Hi, I'm quite new to iPhone OpenGL ES, and I'm really stuck. I was trying to implement shadow mapping on iPhone, and I allocated two 512*1024*32bit textures for the shadow map and the diffuse map respectively. The problem is that my application started to freeze and reboot the device after I added the shadow map allocation part to the code (so I guess the shadow map allocation is causing all this mess). It happens randomly, but mostly within 10 minutes. (sometimes within a few secs) And it only happens on the real iPhone device, not on the virtual device. I backtracked the problem by removing irrelevant code lines by lines and now my code is really simple, but it's still crashing (I mean, freezing). Could anybody please download my xcode project linked below and see what on earth is wrong? The code is really simple: http://www.tempfiles.net/download/201004/95922/CrashTest.html I would really appreciate if someone can help me. My iPhone is a 3GS and running on the OS version 3.1. Again, run the code and it'll take about 5 mins in average for the device to freeze and reboot. (Don't worry, it does no harm) It'll just display cyan screen before it freezes, but you'll be able to notice when it happens because the device will reboot soon, so please be patient. Just in case you can't reproduce the problem, please let me know. (That could possibly mean it's specifically my device that something's wrong with) Observation: The problem goes away when I change the size of the shadow map to 512*512. (but with the diffuse map still 512*1024) I'm desperate for help, thanks in advance! Just for the people's information who can't download the link, here is the OpenGL code: #import "GLView.h" #import <OpenGLES/ES2/glext.h> #import <QuartzCore/QuartzCore.h> @implementation GLView + (Class)layerClass { return [CAEAGLLayer class]; } - (id)initWithCoder: (NSCoder*)coder { if ((self = [super initWithCoder:coder])) { CAEAGLLayer* layer = (CAEAGLLayer*)self.layer; layer.opaque = YES; layer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool: NO], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; displayLink_ = nil; context_ = [[EAGLContext alloc] initWithAPI: kEAGLRenderingAPIOpenGLES2]; if (!context_ || ![EAGLContext setCurrentContext: context_]) { [self release]; return nil; } glGenFramebuffers(1, &framebuffer_); glBindFramebuffer(GL_FRAMEBUFFER, framebuffer_); glViewport(0, 0, self.bounds.size.width, self.bounds.size.height); glGenRenderbuffers(1, &defaultColorBuffer_); glBindRenderbuffer(GL_RENDERBUFFER, defaultColorBuffer_); [context_ renderbufferStorage: GL_RENDERBUFFER fromDrawable: layer]; glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, defaultColorBuffer_); glGenTextures(1, &shadowColorBuffer_); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, shadowColorBuffer_); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, 512, 1024, 0, GL_RGBA, GL_UNSIGNED_BYTE, NULL); glGenTextures(1, &texture_); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, texture_); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, 512, 1024, 0, GL_RGBA, GL_UNSIGNED_BYTE, NULL); } return self; } - (void)startAnimation { displayLink_ = [CADisplayLink displayLinkWithTarget: self selector: @selector(drawView:)]; [displayLink_ setFrameInterval: 1]; [displayLink_ addToRunLoop: [NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; } - (void)useDefaultBuffers { glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_RENDERBUFFER, defaultColorBuffer_); glClearColor(0.0, 0.8, 0.8, 1); glClear(GL_COLOR_BUFFER_BIT); } - (void)useShadowBuffers { glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, shadowColorBuffer_, 0); glClearColor(0, 0, 0, 0); glClear(GL_COLOR_BUFFER_BIT); } - (void)drawView: (id)sender { NSTimeInterval startTime = [NSDate timeIntervalSinceReferenceDate]; [EAGLContext setCurrentContext: context_]; [self useShadowBuffers]; [self useDefaultBuffers]; glBindRenderbuffer(GL_RENDERBUFFER, defaultColorBuffer_); [context_ presentRenderbuffer: GL_RENDERBUFFER]; NSTimeInterval endTime = [NSDate timeIntervalSinceReferenceDate]; NSLog(@"FPS : %.1f", 1 / (endTime - startTime)); } - (void)stopAnimation { [displayLink_ invalidate]; displayLink_ = nil; } - (void)dealloc { if (framebuffer_) glDeleteFramebuffers(1, &framebuffer_); if (defaultColorBuffer_) glDeleteRenderbuffers(1, &defaultColorBuffer_); if (shadowColorBuffer_) glDeleteTextures(1, &shadowColorBuffer_); glDeleteTextures(1, &texture_); if ([EAGLContext currentContext] == context_) [EAGLContext setCurrentContext: nil]; [context_ release]; context_ = nil; [super dealloc]; } @end
