ios中UIView的视频播放

Question

我正在使用objective-c开发一个应用程序。

在我的UIViewController中

.h文件

@property(weak,nonatomic)IBOutlet UIView *vvv;

.m文件

  // to play the video
    NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"alphabet learning splash" ofType:@"mp4"];
    NSURL *fileURL = [NSURL fileURLWithPath:filepath];


    self.avPlayer = [AVPlayer playerWithURL:fileURL];
    self.avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;
    AVPlayerLayer *videoLayer = [AVPlayerLayer playerLayerWithPlayer:self.avPlayer];

    [_vvv.layer addSublayer:videoLayer];
    [self.view addSubview:_vvv];
    [ self.avPlayer play];

但视频没有显示在vvv的UIView中。如何设置？

Answer 1

尝试设置界限

// to play the video
NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"alphabet learning splash" ofType:@"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];


self.avPlayer = [AVPlayer playerWithURL:fileURL];
self.avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;
AVPlayerLayer *videoLayer = [AVPlayerLayer playerLayerWithPlayer:self.avPlayer];

[_vvv.layer addSublayer:videoLayer];
[self.view addSubview:_vvv];
_vvv.frame = self.bounds;
[ self.avPlayer play];
