Iphone 将imageview添加到图层

我相信这很简单，但我正在尝试向层中添加一组图像。以下是我到目前为止的情况：

// Create the fish layer
 fishLayer = [CALayer layer];
 //fish  = [UIImageView imageNamed:@"Fish.png"];

 fish.animationImages = [NSArray arrayWithObjects:
        [UIImage imageNamed:@"swim01.png"],
        [UIImage imageNamed:@"swim02.png"],
        [UIImage imageNamed:@"swim03.png"],
        [UIImage imageNamed:@"swim04.png"],
        [UIImage imageNamed:@"swim05.png"],
        [UIImage imageNamed:@"swim06.png"],
        [UIImage imageNamed:@"swim05.png"],
        [UIImage imageNamed:@"swim04.png"],
        [UIImage imageNamed:@"swim03.png"],
        [UIImage imageNamed:@"swim02.png"], nil];

 fish.animationDuration = 1.50;
 fish.animationRepeatCount = -1;
 [fish startAnimating];


 //[self.view addSubview:fish];
 //This should add the animated array to layer.
 fishLayer.contents = fish;

 fishLayer.bounds = CGRectMake(0, 0, 56, 56);
 fishLayer.position = CGPointMake(self.view.bounds.size.height / 2,
         self.view.bounds.size.width / 2);

[self.view.layer addSublayer:fishLayer];

没有错误，但图像阵列不会显示在屏幕上。我想也许这条线就是问题所在

fishLayer.contents = fish;

我已将imageview添加到头文件中，并将其添加到XIB中

如果可以的话，请帮忙

干杯

Adam正在阅读您的代码，看起来您没有初始化fish。由于没有得到任何错误，我假设它是一个实例变量，这意味着它最初被设置为nil。因此，当您设置fish.animationImages时，您实际上什么也不做fish为零。在这个代码片段中，fish的其他用法也是如此

看起来您最初使用的是视图，但后来注释掉了所有这些。为什么要使用图层？您应该能够做到这一点：

fish = [UIImageView imageNamed:@"Fish.png"];

fish.animationImages = [NSArray arrayWithObjects:
        [UIImage imageNamed:@"swim01.png"],
        [UIImage imageNamed:@"swim02.png"],
        [UIImage imageNamed:@"swim03.png"],
        [UIImage imageNamed:@"swim04.png"],
        [UIImage imageNamed:@"swim05.png"],
        [UIImage imageNamed:@"swim06.png"],
        [UIImage imageNamed:@"swim05.png"],
        [UIImage imageNamed:@"swim04.png"],
        [UIImage imageNamed:@"swim03.png"],
        [UIImage imageNamed:@"swim02.png"], nil];

fish.animationDuration = 1.50;
fish.animationRepeatCount = -1;
[fish startAnimating];

[self.view addSubview:fish];

fish.bounds = CGRectMake(0, 0, 56, 56);
fish.position = CGPointMake(self.view.bounds.size.height / 2,
         self.view.bounds.size.width / 2);
