得到UIView的viewcontroller（iphone） [英] get UIView's viewcontroller (iphone)

问题描述

我这样做是为了获得视图：

I've done this to get the view:

[self.superview viewWithTag:10]

但是如何获得该视图的viewcontroller。就像你可以获得viewcontroller的视图一样，我想转向其他方式，这样我就可以向该viewcontroller发送一条消息（调用一个方法）。例如：

But how can I get that view's viewcontroller. Just like you can get the the viewcontroller's view I want to go the other way so I can send a message (call a method) to that viewcontroller. eg:

[[self.superview viewWithTag:10].viewController doSomething];

（显然不是实际的代码，但我想要这样的东西）

(obviously that not actual code but I want something like that)

推荐答案

您可以使用 -neResponder 方法来执行此操作：

You can use the -nextResponder method to do it:

[(YourUIViewController *)[[self.superview viewWithTag:10] nextResponder] doSomething];

根据 http://developer.apple.com/library/ios/documentation/uikit/ reference / UIResponder_Class / Reference / Reference.html＃// apple_ref / occ / instm / UIResponder / nextResponder ，UIView通过返回管理它的UIViewController对象（如果有的话）或其超级视图来实现此方法（如果它没有）

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)"
