通过UIView对象获取该对象所属的UIViewController可以使用UIResponder的nextResponder方法获得,UIView类继承于UIResponder,因此可以直接使用。
根据文档描述,如果View有view controller,则通过nextResponder方法返回,如果没有则返回superview。
下面是英文原文:
if the view has a view controller, it is returned by nextResponder.
If there is no view controller, the method will return the superview
相关代码如下:遍历该View的树形结构,获取到其所属的ViewController
- (UIViewController*)GetViewController:(UIView*)uView { for (UIView* next = [uView superview]; next; next = next.superview) { UIResponder* nextResponder = [next nextResponder]; if ([nextResponder isKindOfClass:[UIViewController class]]) { return (UIViewController*)nextResponder; } } return nil; }
