How to get a reference to the current window?

Need a ref to the window in which a view is inside (no matter how deep inside). Usually there is only one window in an iPhone app. How would I access that the most easy wa开发者_运维百科y? Is there something cooler than getting the app delegate to access the window?

[[UIApplication sharedApplication] keyWindow]

Well, UIView has the window property...
