iphone - 无法在 didFinishLaunchingWithOptions 中制作动画

Question

我在 didFinishLaunchingWithOptions 中有这段代码:

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

UIViewController *myViewController = [[UINavigationController alloc] initWithRootViewController:[[ViewController alloc] init]];

self.window.rootViewController = myViewController;

[self.window makeKeyAndVisible];

我想让一个 UIImageView 出现，播放动画，然后消失。我将此代码添加到现有代码中，但没有任何反应:

UIImageView *imgView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    NSArray *animationFrames = [[NSArray alloc]initWithObjects:blablahblah, nil];

    imgView.animationImages = animationFrames;
    imgView.animationDuration = 1.5;
    imgView.animationRepeatCount = 1;

我在这里做错了什么？提前致谢!

Answer 1

将代码放入 ViewDidLoad 中。

.m

animation.animationImages = [NSArray arrayWithObjects:

[UIImageimageNamed:@"chicken1.tiff"],

[UIImageimageNamed:@"chicken2.tiff"],

[UIImageimageNamed:@"chicken3.tiff"],nil];

[animationsetAnimationRepeatCount:0];

animation.animationDuration = 1;

[动画开始动画];

.h

IBOutlet UIImageView *动画；
