IOS 6 判断横竖屏

在viewDidLoad中加入

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(detectShowOrientation) name:UIApplicationDidChangeStatusBarOrientationNotification object:nil];

并添加相关函数

-(void)detectShowOrientation{
    if ([UIApplication sharedApplication].statusBarOrientation == UIDeviceOrientationLandscapeLeft ||[UIApplication sharedApplication].statusBarOrientation == UIDeviceOrientationLandscapeRight)     {//
        NSLog(@"videolist 横屏");
       }else{//
        NSLog(@"videoList 竖屏");
       }
}
