问题描述

有一种方法可以从 UIView 对象中获取视图控制器引用？我需要这样的：

There is a way to get a view controller reference from a UIView object? I need something like this:

MyParentViewController *myParentViewController = [self.view.superview controller];

推荐答案

您可以使用 nextResponder 方法。根据 http： //developer.apple.com/library/ios/documentation/uikit/reference/UIResponder_Class/Reference/Reference.html#//apple_ref/occ/instm/UIResponder/nextResponder ，UIView通过返回UIViewController对象（如果它有一个）或其superview（如果没有）

You can use the -nextResponder method to do it. According to http://developer.apple.com/library/ios/documentation/uikit/reference/UIResponder_Class/Reference/Reference.html#//apple_ref/occ/instm/UIResponder/nextResponder , "UIView implements this method by returning the UIViewController object that manages it (if it has one) or its superview (if it doesn’t)"
