1.新建single view工程，导入MediaPlayer库，导入一个视频文件test1.mp4

2.ViewController.h

    #import <UIKit/UIKit.h>        #import <MediaPlayer/MediaPlayer.h>                @interface ViewController : UIViewController {            MPMoviePlayerViewController *_playerVC;        }        @end  

2.ViewController.m

    #import "ViewController.h"                @implementation ViewController                - (void)viewDidLoad        {            [super viewDidLoad];                        NSString *path = [[NSBundle mainBundle] pathForResource:@"test1" ofType:@"mp4"];            NSLog(@"%@", path);            NSURL *url = [NSURL fileURLWithPath:path];            _playerVC = [[MPMoviePlayerViewController alloc] initWithContentURL:url];                        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];            button.frame = CGRectMake(100, 100, 100, 40);            [button addTarget:self action:@selector(play) forControlEvents:UIControlEventTouchUpInside];            [self.view addSubview:button];        }                - (void)play        {            [self presentMoviePlayerViewControllerAnimated:_playerVC];            [_playerVC.moviePlayer play];        }                @end
