大佬教程收集整理的这篇文章主要介绍了ios – 在AVPlayerLayer上拉伸视频，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
- (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,但它不会在整个屏幕上填充(如果需要的话),但它只调整大小以保持其宽高比：我已经尝试了“videoGravity”的所有三个值…似乎没有任何改变.
我怎么解决？
谢谢
