Objective C - addobserver 用于 UIView 添加子视图？
有没有一种简单的方法可以监听子视图或子视图何时添加到 UIView 中？
我已经浏览了 addobserver 选项，但还没有找到明显的选项。当内容添加到视图时，可能还有另一个选项会受到影响，还是我说错了？即内容的宽度或高度、位置等？
编辑 使用下面@Alkimake的建议（TextHolderClass）可以轻松完成此操作。 我创建了一个自定义 UIView 子类，并将 Interface Builder 中的 UIView 类设置为等于 TextHolderClass
感谢您的帮助，我知道这应该是显而易见的:)
Is there an easy way for listening for when a child or subview has been added to a UIView?
I've gone through the addobserver options and haven't found an obvious option anyway. There may be another option that would be affected though when content is added to a view or am I wrong in saying that? i.e. content width or height, positions, etc.?
Edit
This is accomplished easily using the advice of @Alkimake below (TextHolderClass).
I created a custom UIView subclass and set the UIView's class in Interface Builder to be equal to TextHolderClass
Thanks for your help, I know it should have been obvious :)
