You can save changed data in NSUserDefaults in settings , then when back to mainview, use saved data in -(void)viewWillAppear:(BOOL)animated: method in mainviewController or -drawView: method in mainview.

You could use an NSNotification to send a message from one view controller to the other. But I agree with the other answer that regardless of whether you use shared NSUserDefaults or an NSNotification (or both), or some other means of communication between one view controller and the other (e.g. just give the primary view controller some methods that the settings view controller can call), what you're going to be communicating is state; the actual changes will be reflected because you've set up the primary view controller's viewWillAppear to consult that state and construct the interface accordingly.
