推荐答案

如果您需要一个实际的按钮，那么选择很明确:您将需要构建自己的自定义 UIControl 对象以实现此目的.您很可能可以仅继承UIButton，并以这种方式处理动画图像.我在一个应用程序中使用核心动画在一系列6张图像之间淡入淡出，做了类似的事情.效果很好.

If you need an actual button, then the choice is clear: You will need to build your own custom UIControl object to achieve this. Quite possibly you can just subclass UIButton, and handle animating the images that way. I do something similar in one of my apps using core animation to fade between a series of 6 images. It works quite well.

我将指向您 UIControl类参考.请阅读该页面上的介绍材料，该材料链接到其他页面，例如事件处理.同样，我还将指向您CABasicAnimation类引用，并应用了相同的警告.

I will point you at the UIControl class reference. Please read the intro material on the page, it links to other pages, like event handling. As well, I will also point you at the CABasicAnimation class reference, with the same caveat applied.

请记住，UIControl只是UIView，只是它以特定方式处理事件.

Remember, a UIControl is just a UIView, except that it handles events a particular way.
