我试过 UIImageView * tempCopy = [实例复制] 但它崩溃了。还有另一种方法吗？
I've tried UIImageView *tempCopy = [instance copy] but it crashes. Is there another way?
推荐答案
它可能崩溃，因为UIImageView不符合 NSCopying 协议。所以自己动手：实例化一个新的UIImageView并设置您感兴趣的原始属性。
It probably crashes because UIImageView doesn't conform to the NSCopying protocol. So do it yourself: instantiate a new UIImageView and set any property from your original that you find of interest.
