Hello

The best way is to use your AppDelegate.

[ (AppDelegate*)[ [ UIApplication sharedApplication ] delegate ] doSomething ];

Good Luck ! Vincent

You could do: [[subsubView superview] superview] to get a reference to your mainview. Or you could use a subclass for your subsubview and give it a property and set it to keep a reference to its super-viewcontroller upon creation.

Edit: Forget about superview, it works only for views, you're interested in viewcontrollers. Sorry I got you wrong. Try keeping a reference, besides using a property in the VC itself, you could store it in the appdelegate or another singleton to make it easy to access.
