Since iOS 7.0,you can use UIViewControllerTransitionCoordinator to add a push completion block:

UINavigationController *nav = self.navigationController;
[nav pushViewController:vc animated:YES];

id coordinator = vc.transitionCoordinator;
[coordinator animateAlongsideTransition:^(id  _Nonnull context) {

} completion:^(id  _Nonnull context) {
    NSLog(@"push completed");
}];
