avplayer全屏

Question

我有一个和AVAsset一起用来播放视频的AVPlayer。

我添加了一些控件，如播放、停止、前进等。

但是我怎么才能用一个按钮切换到全屏呢？我不想使用MPMoviePlayerController，因为我不知道如何同步开始时间。但是如何才能简单地“扩展”当前的playerView来使用fullScreen呢？

谢谢。

Answer 1

如果AvPlayer与view或window 具有相同的框架，则为

- To make AVPlayer as full screen you have to give total frame of window to AVPlayer layer than rotate a view by pi/2 . 

​

如果AvPlayer具有较少的视图框架或window，则为window

- Create on protocal to parent to change frame of player to window frame when user presses landscape button 
- Rotate a view by pi/2. 

​

创建一个方法并使用下面的代码。

-(void)enlarge
{
    if(!_isLandscapeMode)
    {
        [self.landscapeDelegate changeFrameForLandscapeMode:YES];
        [_landscapeMode setImage:[UIImage imageNamed:IMAGE_NAME_PORTRAIT_MODE] forState:UIControlStateNormal];
        _isLandscapeMode=YES;

        self.transform =  CGAffineTransformMakeRotation(M_PI_2);
    }
    else
    {
        [self.landscapeDelegate changeFrameForLandscapeMode:NO];
        _isLandscapeMode=NO;
        [_landscapeMode setImage:[UIImage imageNamed:IMAGE_NAME_LANDSCAPE_MODE] forState:UIControlStateNormal];
        self.transform =  CGAffineTransformMakeRotation(0);
    }
}

假设您有一个具有UIView全屏的UIViewController

您需要使用AVPlayerLayer

var player = AVPlayer(playerItem: AVPlayerItem(asset: asset))
var layer = AVPlayerLayer(player: player)
self.view.layer.addSublayer(layer)
layer.frame = CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)

我也有同样的问题。我在代码中添加了以下几行代码：

 [playerLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill];

它现在将全屏显示。
