objective-c - Xcode 7 GM(iOS9) 不支持启动画面动画。应用程序因错误而崩溃

Question

在我的应用程序中，我使用以下代码来显示动画启动画面。应用程序在 Xcode-6.4(iOS 8) 中运行良好，但进入 Xcode-7GM 版本 (iOS9) 应用程序崩溃并出现错误。

window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    imageArray = [[NSMutableArray alloc] initWithCapacity:IMAGE_COUNT];
    // Build array of images, cycling through image names
    for (int i = 1; i <= IMAGE_COUNT; i++)
     [imageArray addObject:[UIImage imageNamed:
                               [NSString stringWithFormat:@"image__%d.png",i]]];
    animationImageView  = [[UIImageView alloc]  initWithFrame:self.window.bounds];
    animationImageView  .animationImages=[NSArray arrayWithArray:imageArray];
    // One cycle through all the images takes 3.5 seconds
    animationImageView .animationDuration = 3.5;
    // Repeat forever
    animationImageView  .animationRepeatCount = 0;
    // Add subview and make window visible
    [window addSubview:animationImageView  ];
    [window makeKeyAndVisible];
    // Start it up animations
    [animationImageView   startAnimating];
    // Wait 3.5 seconds, then stop animation
   [self performSelector:@selector(stopAnimation) withObject:nil afterDelay:3.5];`

这是我在使用 Xcode-7GM 时收到的错误消息:

Assertion failure in -[UIApplication _runWithMainScene:transitionContext:completion:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3505.16/UIApplication.m:3294

Answer 1

    window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

改为

    [window setFrame:[[UIScreen mainScreen] bounds]];
