UINavigationController后退按钮一半在iPad横向工作 [英] UINavigationController back button half works in iPad landscape orientation

问题描述

在带有UINavigationController的iPad应用程序中，一切都在纵向模式下工作，但在横向模式下，后退按钮有时只会返回半个级别。也就是说，在第一次按下时，标题栏会动画，好像它正在弹出一个控制器，而在第二次按下时，它会动画内容弹出。

In an iPad application with a UINavigationController, everything works in portrait mode but in landscape mode the back button sometimes only goes back half a level. That is to say, on the first press the title bar animates as if it was popping a controller, and on the second press it animates the content popping.

有没有人找到解决这个问题？这个问题中的矛盾解决方案没有帮助。我在导航控制器中有一个shouldAutorotate方法，但没有其他方法。

Has anyone found a solution to this? The contradictory solution in this question did not help. I have a shouldAutorotate method in the navigation controller but no others.

-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)inOrientation {
    return YES;
}

编辑：

实际上，第一次点击弹出内容，第二次点击弹出导航栏。

actually, the first click pops the content and the second click pops the navigation bar.

推荐答案

as David F 想通了，但我没有理解，每个视图控制器必须实现一个shouldAutorotate方法，如果导航控制器。即使它会继续旋转，你在iPhone上也不需要它，但不知何故，iPad认为视图控制器需要双重弹出，如果它没有响应那个方法，结果与导航控制器相同。

As David F figured out but I did not grok, every view controller must implement a shouldAutorotate method if the navigation controller does. Even though it will go ahead and rotate, and you do not need it on the iPhone, somehow the iPad thinks a view controller needs a double pop if it does not respond to that method with the same result as the navigation controller.
