ios - 隐藏iPhone X的首页指示符

我有一个带视频播放器的iOS应用，正在播放视频(横向，全屏)时，我想在iPhone X上隐藏主页指示器。

if (@available(iOS 11.0, *)) {
     [self setNeedsUpdateOfHomeIndicatorAutoHidden];
}

并且

-(BOOL)prefersHomeIndicatorAutoHidden{
   return YES;
}

但没有运气。有人有什么主意吗？

最佳答案

因此，如果您使用的是childViewController，则需要实现childViewControllerForHomeIndicatorAutoHidden作为 -

迅捷

extension UINavigationController {
    open override func childViewControllerForHomeIndicatorAutoHidden() -> UIViewController? {
        return DemoViewController.loadFromNib()
    }
}

//DemoViewController is childViewController
class DemoViewController: UIViewController {
    static func loadFromNib() -> DemoViewController{
        let storyBoardInst = UIStoryboard(name: "Main", bundle: nil)
        return storyBoardInst.instantiateViewController(withIdentifier: "DemoViewController") as! DemoViewController
    }

    override func prefersHomeIndicatorAutoHidden() -> Bool {
        return true
    }
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(true)
        view.backgroundColor = .red
        if #available(iOS 11.0, *) {
            //Notifies UIKit that your view controller updated its preference regarding the visual indicator
            setNeedsUpdateOfHomeIndicatorAutoHidden()
        }
    }
}

objective-c -

@interface UINavigationController(custom)
@end
@implementation UINavigationController(custom)
-(UIViewController *)childViewControllerForHomeIndicatorAutoHidden{
    return [self.storyboard  instantiateViewControllerWithIdentifier:@"DemoViewController"];
}
@end
    //DemoViewController is childViewController
@interface DemoViewController ()
@end
@implementation DemoViewController
-(BOOL)prefersHomeIndicatorAutoHidden{
    return YES;
}
-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:YES];
    self.view.backgroundColor = [UIColor redColor];
    //Notifies UIKit that your view controller updated its preference
    // regarding the visual indicator
    if (@available(iOS 11.0, *)) {
        [self setNeedsUpdateOfHomeIndicatorAutoHidden];
    }
}
