需求：调用IOS自带播放器播放本地MP4文件

需求：需要调用IOS自带播放器播放本地MP4文件

实现代码：

1、导入MediaPlayer.framework

2、导入头文件

#import <MediaPlayer/MediaPlayer.h>

3、使用代码

-(void)playLocalFile:(NSString *)absoluteFileName{
    NSURL *URL = [NSURL fileURLWithPath:absoluteFileName];
    MPMoviePlayerViewController  * moviePlayerController = [[MPMoviePlayerViewController alloc] initWithContentURL:URL];
    [self presentMoviePlayerViewControllerAnimated:moviePlayerController];
    moviePlayerController.moviePlayer.movieSourceType=MPMovieSourceTypeFile;
}

4、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];

}
