ios9后系统推荐使用 AVPlayerViewController 来取代 MPMoviePlayerViewController ，其OC使用参考代码如下
@import AVKit;
@import AVFoundation;
- (void)onVideoHelpClick:(UIGestureRecognizer *)gestureRecognizer{
NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"instruction" ofType:@"mp4"];
// videoPath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"instruction.mp4"];
NSURL *url = [NSURL fileURLWithPath:videoPath];
AVPlayer *player = [AVPlayer playerWithURL:url];
AVPlayerViewController *playerViewController = [AVPlayerViewController new];
playerViewController.player = player;
[self presentViewController:playerViewController animated:YES completion:nil];
[playerViewController.player play];
}
