UIDevice Orientation [英] UIDevice Orientation

问题描述

我在方法中有以下代码。当我在模拟器中运行它时，调试器跳过代码？我缺少什么？

I have the following code in a method. When I run this in the simulator the debugger skips right over the code?? What am I missing?

if (([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft) || 
        ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight)) 
{       

} else {

}

这应该没关系，但是尝试打开方向通知：

This shouldn't matter, but try turning on orientation notifications:

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];


[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(detectOrientation) name:@"UIDeviceOrientationDidChangeNotification" object:nil];

Update

我的不好，我以为它是空的。

My bad, I assumed it was empty.

尝试删除or语句，然后测试单个方向。看看是否能修复它。也许有一个支架问题或者傻事。

Try removing the or statement and just test for a single orientation. See if that fixes it. Maybe there is a bracket problem or something silly.

我在生产代码中进行了以下测试，所以你的技术应该可行：

I have the following test working in production code, so your technique should work:

    if (([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft) || 
        ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight)) {


}

Original Answer

你必须在if块中实际放置语句才能让它进入。

You have to actually put statements in the if blocks to get it to step in.

调试器非常智能，可以跳过空块。

The debugger is smart enough to skip over empty blocks.
