iphone - UI设备方向

Question

我的方法中有以下代码。当我在模拟器中运行它时，调试器会直接跳过代码？我错过了什么？

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

} else {

}

确定界面方向的最佳方法是查看状态栏方向:

 UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];

    if(orientation == UIInterfaceOrientationPortrait || 
       orientation == UIInterfaceOrientationPortraitUpsideDown) {

       //Portrait orientation

}

if(orientation == UIInterfaceOrientationLandscapeRight ||
   orientation == UIInterfaceOrientationLandscapeLeft) {

    //Landscape orientation

}

UIDevice 类根据加速度计测量方向，如果设备平放，它将不会返回正确的方向。
