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)

Answer 1

Views shouldn't need to do that.
