播放视频与音频，可以加入导唱，即多加一个音轨同时播放。同时，可以使用播放时的缓冲文件功能。
用法： playView = [[HCPlayerWrapper alloc] initWithFrame:CGRectMake(0, 0, screenWidth_, playerHeightMax_)]; playView.delegate = self; [self.view addSubview:playView]; playView.userInteractionEnabled = YES;
//是否使用缓存
[[UserManager sharedUserManager]currentSettings].EnbaleCacheWhenPlaying = YES;
[playView setLyricBottomSpace:30];
[playView setPlayRange:10 end:-1];
playView.backgroundColor = [UIColor blackColor];
有3种方式设置需要播放的源：
1、直接设置PlayerItem:
AVURLAsset *movieAsset = nil;
NSString * urlString = 。。。。。。;
movieAsset = [AVURLAsset URLAssetWithURL:[NSURL URLWithString:urlString] options:nil];
AVPlayerItem * playerItem = [AVPlayerItem playerItemWithAsset:movieAsset];
[playView setPlayeritem:playerItem lyric:nil];
2、直接设置URL：
[playView setPlayerUrl:[NSURL URLWithString:urlString] lyric:nil];
3、使用MTV：
[playView setPlayerData:currentMtv_ sample:nil];
播放：
[playView setPlayRate:1];
playView.isLoop = YES;
[playView play];
