iOS - 将特定的UIViewController锁定到特定方向 [英] iOS - Lock a specific UIViewController to a specific orientation

问题描述

我的应用程序支持每4个方向，我有一个 UIViewController ，它位于 LandscapeRight 中。
我使用 UINavigationController 推送 UIViewController ，我想要 UIViewController 仅在 UIInterfaceOrientationLandscapeRight 中，但当我旋转手机时，它会切换回其他方向。

My application supports every 4 orientation, I have a UIViewController which is in LandscapeRight. I am using UINavigationController to push that UIViewController, i want that UIViewController to be only in UIInterfaceOrientationLandscapeRight but when I rotate the phone, it switches back to other Orientation.

-(BOOL)shouldAutorotate{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationLandscapeRight;
}

-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    return UIInterfaceOrientationLandscapeRight;
}

推荐答案

只需删除那些shouldAutorotate，supportedInterfaceOrientations和preferredInterfaceOrientationForPresentation。

just remove those shouldAutorotate, supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation.

并将其添加到您想要仅显示横向的viewcontroller。

and add this to the viewcontroller you want to display landscape only.

-(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。
