在 AVPLayerViewController 中添加 activity 指标？（注意：当视频处于全屏模式时）

Question

enter image description here如何在AVPLayerViewController全屏模式下在中间添加activity指示器？

Answer 1

您可以通过在主键上添加自定义视图来在 AVPLayerViewController 中心添加自定义指示器视图 window。

UIApplication.shared.keyWindow?.addSubview(your custom indicator view)

您可以如下设置自定义指标视图的中心。

activity.center = CGPoint.init(x: UIScreen.main.bounds.size.width/2.0, y: UIScreen.main.bounds.height/2.0)

Answer 2

当用户按下播放按钮时添加此代码

if(playerViewController.view.subviews.count != 0)
{
  UIView *AVTouchIgnoringView = playerViewController.view.subviews[0].subviews.lastObject;
  activityIndicatorBuffer.center = playerViewController.view.center;
  [AVTouchIgnoringView addSubview:activityIndicatorView];
  [AVTouchIgnoringView bringSubviewToFront:activityIndicatorView];
}

别忘了添加以下方法

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [playerViewController addObserver:self forKeyPath:@"videoBounds" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:nil];
}
-(void)viewDidDisappear:(BOOL)animated
{
     [super viewDidDisappear:animated];
     [playerViewController removeObserver:self forKeyPath:@"videoBounds"];
}
-(void)observeValueForKeyPath:(NSString )keyPath ofObject:(id)object change:(NSDictionary )change context:(void *)context
{
     if ([keyPath isEqualToString:@"videoBounds"])
     {
        float height = playerViewController.contentOverlayView.bounds.size.height;
        float width = playerViewController.contentOverlayView.bounds.size.width;
        if (height == SCREEN_HEIGHT && width == SCREEN_WIDTH)
        {
            activityIndicatorBuffer.center = playerViewController.contentOverlayView.center;
        }
        else
        {
            activityIndicatorBuffer.center = playerViewController.view.center;    
        }
     }
}

并且不要忘记在缓冲时开始动画。单击此处
