Navigate Back to previous view controller

Question

I have a UIView->UICollectionView->UICollectionViewCell. I am trying to navigate back programatically but none of these works. The code did called. I am using StoryBoard.

- (void) goBack:(NSNotification *) notification {
      // [self.navigationController popViewControllerAnimated:YES];
     //  [self dismissViewControllerAnimated:YES completion:nil];
      [self.navigationController popToRootViewControllerAnimated:YES];
}

Answer 1

You need to use:

[self.navigationController popToRootViewControllerAnimated:YES];

This will bring you back to the root view controller.

If you want to navigate back to previous view controller, you should implement:

[self.navigationController popViewControllerAnimated:YES];

Answer 2

By using below line we can go to parent view controller

[self.navigationController popViewControllerAnimated:YES]; 

By using below line we can move to main/root view controller

[self.navigationController popToRootViewControllerAnimated:YES]; 

By using below line we can move to any view controller

[self.navigationController popToViewController:viewControllerObject animated:YES];
