我的应用程序支持每4个方向,我有一个在LandscapeRight中的UIViewController.
我正在使用UINavigationController来推送UIViewController,我希望UIViewController仅在UIInterfaceOrientationLandscapeRight中,但是当我旋转手机时,它会切换回其他方向.

-(BOOL)shouldAutorotate{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationLandscapeRight;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationLandscapeRight;
}
解决方法
只需删除那些shouldAutorotate,supportedInterfaceOrientations和preferredInterfaceOrientationForPresentation.
并将此添加到您想要仅显示横向的viewcontroller.
-(void)viewDidAppear:(BOOL)animated{
[[UIDevice currentDevice] setValue:
[NSNumber numberWithInteger: UIInterfaceOrientationLandscapeLeft]
forKey:@"orientation"];
}
实际上,这是来自类似问题的解决方案.
