iOS简单流媒体播放

原文:cocoa自学 - 人人小站 

首先需要引用framework：MediaPlayer.framework

然后在头文件中

1#import

2@property (nonatomic,retain) MPMoviePlayerController *player;

在M文件中开始实现方法

1/**

2@method 播放视频

3*/

4- (void)playMovie:(NSString *)fileURL{

5//本地视频文件路径

6//    NSString *path = [[NSBundle mainBundle] pathForResource:fileName ofType:@"mp4"];

7//网络视频URL

8NSURL *url = [NSURL URLWithString:fileURL];

9//    NSLog(@"%@", url);

10//视频播放对象

11self.player = [[MPMoviePlayerController alloc] init];

12//设置为流媒体模式

13self.player.movieSourceType = MPMovieSourceTypeStreaming;

14[self.player setControlStyle:MPMovieControlStyleFullscreen];

15[self.player.view setFrame:self.view.bounds];

16[self.player setContentURL:url];

17self.player.fullscreen = YES;//全屏播放

18self.player.initialPlaybackTime = -1;

19[self.view addSubview:self.player.view];

20// 注册一个播放结束的通知

21[[NSNotificationCenter defaultCenter] addObserver:self

22selector:@selector(myMovieFinishedCallback:)

23name:MPMoviePlayerPlaybackDidFinishNotification

24object:self.player];

25[self.player prepareToPlay];

26//    [sharedData stopLoading];

27[self.player play];

28}

29#pragma mark -------------------视频播放结束委托--------------------

30/*

31@method 当视频播放完毕释放对象

32*/

33- (void)myMovieFinishedCallback:(NSNotification*)notify

34{

35//视频播放对象

36MPMoviePlayerController* theMovie = [notify object];

37//销毁播放通知

38[[NSNotificationCenter defaultCenter] removeObserver:self

39name:MPMoviePlayerPlaybackDidFinishNotification

40object:theMovie];

41// 释放视频对象

42[theMovie.view removeFromSuperview];

43}

通过调用[self playMovie:videoURL];就可以播放视频文件了
