如何在iOS5中获得默认的LandscapeLeft方向？ [英] How to get default LandscapeLeft Orientation in iOS5?

问题描述

很抱歉，如果这个问题重复，但我找不到相同的解决方案。
在iOS6中，如果我想为一个UIViewController设置默认方向，我只需使用：

Sorry if this question is duplicate, but I can't find the same solution. In iOS6, if I want to set default orientation for one UIViewController, I just use:

- (BOOL)shouldAutorotate {
    return YES;
}
- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskLandscapeLeft;
}

但是如何在iOS5中做同样的事情，我测试两者：

But how to do same in iOS5, I test both:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);//not default
}
and
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return (toInterfaceOrientation == UIInterfaceOrientationMaskLandscapeLeft);// = return NO;
}

但默认方向始终是Portrait.Any建议？

But the default orientation always Portrait.Any suggestion?

推荐答案

调用以下方法，你要检查orientation.happy编码的状态： - ）

call the below method where you want to check the status of orientation.happy coding :-)

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [self CheckForViewForOrientation:toInterfaceOrientation];
}

- (void) CheckForViewForOrientation:(UIInterfaceOrientation)orientation
{
    if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
    {
        //Ur lable portrait view
    }
    else if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
    {
        //Ur lable for landscape view
    }
}
