我正在使用以下代码在我的 UIView 上显示全屏视频：

- (void)playMovie:(NSString *)name :(NSString *)type
{
    NSURL *movieURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:name ofType:type]];

    self.movieAsset = [AVAsset assetWithURL:movieURL];
    self.movieItem = [[AVPlayerItem alloc] initWithAsset:self.movieAsset];
    self.moviePlayer = [[AVPlayer alloc] initWithPlayerItem:self.movieItem];
    self.moviePlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;
    self.movieLayer.videoGravity = AVLayerVideoGravityResize;

    self.movieLayer = [AVPlayerLayer playerLayerWithPlayer:self.moviePlayer];
    [self.movieLayer setFrame:self.view.frame];

    [self.view.layer addSublayer:self.movieLayer];
    [self.moviePlayer addObserver:self forKeyPath:@"status" options:0 context:nil];

    // Schedule stop after 6 seconds
    [NSTimer scheduledTimerWithTimeInterval:6.0 target:self selector:@selector(stopCurrentMovie:) userInfo:nil repeats:NO];
}

视频正在播放，但它没有填满（如果需要，可以拉伸）整个屏幕，但它只会调整大小以保持其宽度/高度比：我已经尝试了“videoGravity”的所有三个值......似乎没有任何改变。

我该如何解决？谢谢

您设置重力然后重新启动播放器尝试：

- (void)playMovie:(NSString *)name :(NSString *)type
{
 NSURL *movieURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:name ofType:type]];

self.movieAsset = [AVAsset assetWithURL:movieURL];
self.movieItem = [[AVPlayerItem alloc] initWithAsset:self.movieAsset];
self.moviePlayer = [[AVPlayer alloc] initWithPlayerItem:self.movieItem];


self.movieLayer = [AVPlayerLayer playerLayerWithPlayer:self.moviePlayer];
[self.movieLayer setFrame:self.view.frame];
self.moviePlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;
self.movieLayer.videoGravity = AVLayerVideoGravityResize;

[self.view.layer addSublayer:self.movieLayer];
[self.moviePlayer addObserver:self forKeyPath:@"status" options:0 context:nil];

// Schedule stop after 6 seconds
[NSTimer scheduledTimerWithTimeInterval:6.0 target:self selector:@selector(stopCurrentMovie:) userInfo:nil repeats:NO];
}
