UI界面方向LandscapeLeft和UI界面方向landscapeRight是否颠倒?

UIInterfaceOrientationLandscapeLeft

该设备处于横向模式,设备直立,主页按钮在右侧。

UIInterfaceOrientationLandscapeRight

+ (NSString *)NSStringFromUIInterfaceOrientation:(UIInterfaceOrientation)o
{
    switch (o) {
        case UIInterfaceOrientationPortrait: return @"UIInterfaceOrientationPortrait";
        case UIInterfaceOrientationPortraitUpsideDown: return @"UIInterfaceOrientationPortraitUpsideDown";
        case UIInterfaceOrientationLandscapeLeft: return @"UIInterfaceOrientationLandscapeLeft";
        case UIInterfaceOrientationLandscapeRight: return @"UIInterfaceOrientationLandscapeRight";
    }
    return nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    NSLog(@"Should: %@", [[self class] NSStringFromUIInterfaceOrientation:toInterfaceOrientation]);
    return YES;
}    

我将上述代码粘贴到默认的基于导航的应用程序模板的RootViewController.m中。
