get UIView's viewcontroller (iphone)

Question

I've done this to get the view:

[self.superview viewWithTag:10]

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];

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

You can use the -nextResponder method to do it:

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

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)"

Is it really clean and safe to get the view's viewcontroller by calling this method ? – booker Apr 28 '12 at 17:30
