一 MPMoviePlayerController 简介

在iOS中播放视频可以使用MediaPlayer.framework种的MPMoviePlayerController类来完成，它支持本地视频和网络视频播放。这个类实现了MPMediaPlayback协议，因此具备一般的播放器控制功能，例如播放、暂停、停止等。下面列出了MPMoviePlayerController的常用属性和方法：

二 使用方法：设置contentUrl ,view的frame，屏幕模式

#import "ViewController.h"
#import <MediaPlayer/MediaPlayer.h>

@interface ViewController ()

@property (nonatomic,strong) MPMoviePlayerController *moviePlayer;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    [self.moviePlayer play];
    [self addNofi];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/**
 *  视频播放url
 *
 *  @return 返回视频url
 */
- (NSURL *)url
{
    NSString *urlStr = @"http://7xawdc.com2.z0.glb.qiniucdn.com/o_19p6vdmi9148s16fs1ptehbm1vd59.mp4";
    urlStr = [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSURL *url1 = [NSURL URLWithString:urlStr];
    return url1;
}

/**
 *  初始化MPMoviePlayerController
 *
 *  @return 返回一个MPMoviePlayerController的实例
 */
- (MPMoviePlayerController *)moviePlayer
{
    if (!_moviePlayer) {
        _moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[self url]];
        _moviePlayer.view.frame = self.view.frame;
        _moviePlayer.scalingMode = MPMovieScalingModeAspectFit; //固定缩放比例并且尽量全部
        [self.view addSubview:_moviePlayer.view];
    }
    return _moviePlayer;
}

/**
 *  添加视频播放的通知
 */
- (void)addNofi
{
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playbackstateDidChange:)
                                                 name:MPMoviePlayerPlaybackStateDidChangeNotification   //播放状态改变，可配合playbakcState属性获取具体状态
                                               object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playDidFinish:) //媒体播放完成或用户手动退出，具体完成原因可以通过通知userInfo中的key为MPMoviePlayerPlaybackDidFinishReasonUserInfoKey的对象获取
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:nil];
}

- (void)playbackstateDidChange:(NSNotification *)noti
{
    switch (self.moviePlayer.playbackState) {
        case MPMoviePlaybackStateInterrupted:
            //中断
            NSLog(@"中断");
            break;
        case MPMoviePlaybackStatePaused:
            //暂停
            NSLog(@"暂停");
            break;
        case MPMoviePlaybackStatePlaying:
            //播放中
            NSLog(@"播放中");
            break;
        case MPMoviePlaybackStateSeekingBackward:
            //后退
            NSLog(@"后退");
            break;
        case MPMoviePlaybackStateSeekingForward:
            //快进
            NSLog(@"快进");
            break;
        case MPMoviePlaybackStateStopped:
            //停止
            NSLog(@"停止");
            break;

        default:
            break;
    }
}

- (void)playDidFinish:(NSNotification *)noti
{
    //播放完成
}
