Question

Is there a way to monitor what view controller the navigation controller had before it pushed on the current view controller. also the opposite, what view controller it popped off the stack before getting to the current view controller?

Thank you in advance

Answer 1

NSArray *viewControllerArray = [self.navigationController viewControllers];
NSUInteger parentViewControllerIndex = [viewControllerArray count] - 2;
NSLog(@"Parent view controller: %@", [viewControllerArray objectAtIndex:parentViewControllerIndex]);

This should be enough to set a property that keeps track of properties of the last popped view controller.
