5.0-> 6.1没有这样的问题.产生此问题的代码是Cocos2D样板代码,我试图通过注释将其最小化,这是来自App委托的最小代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Create the main window
    window_ = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];


    // CCGLView creation
    CCGLView *glView = [CCGLView viewWithFrame:[window_ bounds]
                                   pixelFormat:kEAGLColorFormatRGB565
                                   depthFormat:0
                            preserveBackbuffer:NO
                                    sharegroup:nil
                                 multiSampling:NO
                               numberOfSamples:0];

    director_ = (CCDirectorIOS*) [CCDirector sharedDirector];

    director_.wantsFullScreenLayout = YES;

    // Display FSP and SPF
    [director_ setDisplayStats:YES];

    // set FPS at 60
    [director_ setAnimationInterval:1.0/60];

    // attach the openglView to the director
    [director_ setView:glView];

    [glView setMultipleTouchEnabled:YES];

    // 2D projection
    [director_ setProjection:kCCDirectorProjection2D];
    //  [director setProjection:kCCDirectorProjection3D];

    // Enables High Res mode (Retina Display) on iPhone 4 and maintains low res on all other devices
    if( ! [director_ enableRetinaDisplay:YES] )
        CCLOG(@"Retina Display Not supported");

    // Default texture format for PNG/BMP/TIFF/JPEG/GIF images
    // It can be RGBA8888,RGBA4444,RGB5_A1,RGB565
    // You can change this setting at any time.
    [CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888];

    // If the 1st suffix is not found and if fallback is enabled then fallback suffixes are going to searched. If none is found,it will try with the name without suffix.
    // On iPad HD  : "-ipadhd","-ipad","-hd"
    // On iPad     : "-ipad","-hd"
    // On iPhone HD: "-hd"
    CCFileUtils *sharedFileUtils = [CCFileUtils sharedFileUtils];
    [sharedFileUtils setEnableFallbackSuffixes:NO];             // Default: NO. No fallback suffixes are going to be used
    [sharedFileUtils setiPhoneRetinaDisplaySuffix:@"-hd"];      // Default on iPhone RetinaDisplay is "-hd"
    [sharedFileUtils setiPadSuffix:@"-ipad"];                   // Default on iPad is "ipad"
    [sharedFileUtils setiPadRetinaDisplaySuffix:@"-ipadhd"];    // Default on iPad RetinaDisplay is "-ipadhd"

    // Assume that PVR images have premultiplied alpha
    [CCTexture2D PVRImagesHavePremultipliedAlpha:YES];

    // Create a Navigation Controller with the Director
    navController_ = [[MyNavigationController alloc] initWithRootViewController:director_];
    navController_.navigationBarHidden = YES;

    // for rotation and other messages
    [director_ setDelegate:navController_];

    // set the Navigation Controller as the root view controller
    [window_ setRootViewController:navController_];

    // make main window visible
    [window_ makeKeyAndVisible];

    return YES;
}

我还从directorDidReshapeProjection启动中注释掉了CCDirector以消除我自己的代码.因此,当应用程序启动时,我只在黑屏上看到帧速率.

我从仪器上看到了同样的结果.

不幸的是无法在设备上测试iOS 7,但我不希望模拟器这样做.

更新：

我用以下结果制作了2个Mark Generations.

所有项目都是64字节分配.我不知道他们是什么类型的.值得一提的是,我正在使用最新稳定的Cocos2D 2.1.

更新#2：

调用64字节分配堆栈.
