  将此代码放在要隐藏导航栏的视图控制器中 .

  - (void) viewWillAppear:(BOOL)animated {
      [super viewWillAppear:animated];
      [self.navigationController setNavigationBarHidden:YES animated:animated];
  }
  

  您可能还想根据自己的需要坚持下去：

  - (void) viewWillDisappear:(BOOL)animated {
      [super viewWillDisappear:animated];
      [self.navigationController setNavigationBarHidden:NO animated:animated];
  }

  以下是 Swift 3 中的操作方法：

  override func viewWillAppear(_ animated: Bool) {
      super.viewWillAppear(animated)
      self.navigationController?.setNavigationBarHidden(true, animated: animated)
  }
  

  附：我发现如果你将动画设置为 false ，推出时会出现一个黑条 . 但是当它设置为 true 时它就像丝绸一样光滑！

  对于iOS 8，可能这个工作可以解决它

  CATransition* transition = [CATransition animation];
          transition.duration = 0.3;
          transition.type = kCATransitionPush;
          transition.subtype = kCATransitionFromRight;
          [self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
          [self.navigationController setNavigationBarHidden:TRUE animated:FALSE];
          [self.navigationController pushViewController:productViewObj animated:FALSE];
          [productViewObj.navigationController setNavigationBarHidden:TRUE animated:FALSE];
          [productViewObj release];
