Question

有关自动旋转到互动的有些奇怪。

在调试器控制台里,

The view controller returned NO from -shouldAutorotateToInterfaceOrientation: for all interface orientations. It should support at least one orientation.

但在现实中,旋转效果很好。信息是错误的。以下是“ 自动旋转到互动方向” 的代码 :

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return ([centerPoint autoRotateFlag]||(interfaceOrientation==centerPoint.userOrientation));
}

自动旋转法拉格(YES)是完全真实的,或者不是中点。用户引导已被固定在四个可接受的值之一上。

这对我来说已经工作了很长时间,应用程序仍然有效。我只是不知道这个信息来自何处。

任何想法吗?

Answer 1

By putting some tracing in my software, using NSLog; I realized that shouldAutorotateToInterfaceOrientation was called seven times before viewDidLoad was called.

由于我的变数自动旋转法拉格仅在通过视图时初始化。这解释了我的问题。

I have to admit though, that I was far from thinking shouldAutorotateToInterfaceOrientation could be called before viewDidLoad. Obviously I was wrong. And I still do not fully understand the order in which all those methods are called.
