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];
}

推荐答案

你需要使用:

[self.navigationController popToRootViewControllerAnimated:YES];

这将带您回到根视图控制器.

This will bring you back to the root view controller.

如果你想导航回之前的视图控制器，你应该实现:

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

[self.navigationController popViewControllerAnimated:YES];
