我一直在寻找这种特殊的方法:didMoveToWindow()但是我还没有找到任何具体的信息。
有人可以解释为什么以及何时应该使用这种方法以及何时调用它?

最佳答案

当 UIView 添加到 Window 对象时,iOS 会调用此方法。
您应该覆盖它以使您的应用程序执行相同的操作。

The default implementation of this method does nothing. Subclasses can override it to perform additional actions whenever the window changes.

The window property may be nil by the time that this method is called, indicating that the receiver does not currently reside in any window. This occurs when the receiver has just been removed from its superview or when the receiver has just been added to a superview that is not attached to a window. Overrides of this method may choose to ignore such cases if they are not of interest.
