翻转由 UINavigationController 管理的 UIViewController 会隐藏导航栏

Question

我已经在 UINavigationContoller 上降低了 2 个级别，并且已经推送了一些视图。现在，我正在查看其中一个推送视图控制器内的图像，当我点击导航栏中的信息按钮时，我希望子视图翻转，将导航栏保留在原位。如何让子视图（被推送的视图）翻转？现在，导航栏也会翻转并阻止我导航回堆栈。

-(void)showImageInfo
{   
    self.imgInfoViewController = [[ImageInfoViewController alloc] initWithNibName:@"ImageInfoViewController" bundle:nil];

    [self.imgInfoViewController setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];

    [self.navigationController presentModalViewController:self.imgInfoViewController animated:YES];

}

来自 UICatalog 示例的代码...我认为它会满足您的需求。基本上你必须做更多的编码才能获得翻转行为。

  - (IBAction)flipAction:(id)sender
    {
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:kTransitionDuration];

        [UIView setAnimationTransition:([self.mainView superview] ? UIViewAnimationTransitionFlipFromLeft :UIViewAnimationTransitionFlipFromRight)                                      forView:self.containerView  cache:YES];
        if ([flipToView superview])
        {
            [self.flipToView removeFromSuperview];
            [self.containerView addSubview:mainView];
        }
        else
        {
            [self.mainView removeFromSuperview];
            [self.containerView addSubview:flipToView];
        }

        [UIView commitAnimations];
    }
