Changing Nav Bar title programmatically
self.navigationController.navigationBar.topItem.title = @"YourTitle";
First check the index of current controller on the navigation stack through
NSLog(@"%@", self.navigationController.viewControllers );after finding the index of current ViewController let say 1.
UINavigationController *navCon = (UINavigationController*) [self.navigationController.viewControllers objectAtIndex:1]; navCon.navigationItem.title = @"Hello";
