iOS - 将特定的 UIViewController 锁定到特定的方向 [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，我在 LandscapeRight 中有一个 UIViewController.我正在使用 UINavigationController 来推送那个 UIViewController，我希望 UIViewController 只在 UIInterfaceOrientationLandscapeRight 中，但是当我旋转时手机，它切换回其他方向.

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

只删除那些 shouldAutorotate、supportedInterfaceOrientations 和 preferredInterfaceOrientationForPresentation.

just remove those shouldAutorotate, supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation.

并将其添加到您只想显示横向的视图控制器中.

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

-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    [[UIDevice currentDevice] setValue:
     [NSNumber numberWithInteger: UIInterfaceOrientationLandscapeLeft]
                                forKey:@"orientation"];
} 

实际上，这是来自一个类似的问题，这里有解决方案.如何在 iOS 8 中强制视图控制器方向?
