推荐答案

你可以使用 UIButton 的imageView属性执行此操作。这将使按钮的行为与通常在其上设置动画的图像一样。这是一个例子：

You can do this using the imageView property of UIButton. This will allow the button to behave as it normally would with your images animating on it. Here's an example:

NSMutableArray *imageArray = [NSMutableArray new];

for (int i = 1; i < 4; i ++) {
    [imageArray addObject:[UIImage imageNamed:[NSString stringWithFormat:@"%d.png",i]]];
}

[myButton setImage:[UIImage imageNamed:@"1.png"] forState:UIControlStateNormal];

[myButton.imageView setAnimationImages:[imageArray copy]];
[myButton.imageView setAnimationDuration:0.5];

[myButton.imageView startAnimating];
