此错误没有意义，因为首选方向 UIInterfaceOrientationLandscapeRight 由支持的方向返回

//iOS6

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return (UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft);
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

错误:

Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'preferredInterfaceOrientationForPresentation must return a supported interface orientation!'

最佳答案

您的代码应如下所示:

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

此外，请确保在您的 Info.plist 中为您的应用设置了正确的方向，因为您从 supportedInterfaceOrientations 返回的内容与 Info 相交。 plist，如果它找不到一个常见的，那么你会得到那个错误。
