Instead Delegate i prefer "NSNotificationCenter" in your case
Add an observer to your ViewController for some action in uiview
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(receiveActionNotification:)
name:@"someActionNotification"
object:nil];
Post Notification from your pushed View in PopOverController Post Notification and method in your Viewcontroller will be called
[[NSNotificationCenter defaultCenter] postNotificationName:@"someActionNotification" object:self];
At the end Dont forget to remove Observer.
[[NSNotificationCenter defaultCenter] removeObserver:@"someActionNotification"];
