问题描述
我有一个用IB制作的UIButton，它被设置为Rounded Rect。有一点，我想把类型改为自定义的代码，是可能吗？
I have an UIButton made with IB, it is set to "Rounded Rect". At one point, I'd like to change the type to "Custom" in the code, is that possible ? I saw the type can be set at creation, but did not see if it was possible to change it later on.
推荐答案
如果在创建时可以设置类型，我没有错，不同的按钮类型由不同的（私有）UIButton的子类表示。这就是为什么您只能在创建时设置类型，而不能设置。
If I'm not mistaken, different button types are represented by different (private) subclasses of UIButton. That's why you can only set type at creation time but not after.
