使用AVPlayer前需要‘“#import <AVFoundation/AVFoundation.h>”，要通过AVPlayer来播放视频需要用到以下3项：
@property(nonatomic,strong)AVPlayer * player; //播放属性
@property(nonatomic,strong)AVPlayerItem * playerItem; //播放属性
@property(nonatomic,strong)AVPlayerLayer * playerLayer; //播放属性
在开发中，单纯使用AVPlayer类是无法显示视频的，要将视频层添加至AVPlayerLayer中，这样才能将视频显示出来

_playerLayer.frame = self.bounds;

把视频播放器的Layer加到视图Layer上,播放视频
[self.layer addSublayer:self.playerLayer];
self.playerItem = [[AVPlayerItem alloc] initWithURL:playerURL];
[_player replaceCurrentItemWithPlayerItem:_playerItem];
[_player play];
