(ios实战)MediaPlayer播放视频

1MediaPlayer内嵌的方式播放视频 

1.1 导入头文件 

#import "MediaPlayer/MediaPlayer.h"

 1.2 定义MoviePlayerController类

创建MoviePlayerController类

player = [[MPMoviePlayerControlleralloc] init];

设置视频路径

NSString *path = [[NSBundlemainBundle] pathForResource:self.questiondata.titleimgofType:@"mp4"inDirectory:nil];

                NSURL *movieURL = [NSURL fileURLWithPath:path];

player.contentURL = movieURL

配置 控件样式

player.controlStyle = MPMovieControlStyleEmbedded;//内嵌的方式

player.controlStyle =MPMovieControlStyleFullscreen; //全屏的方式

 

1.3 将视频控件添加到指定的地方

[player.viewsetFrame:CGRectMake(30,_viewHeight+10,270,97)];

 [selfaddSubview:player.view];

 [player play];

 

1.4 释放控件

 if (player!=nil) {

        [ player stop ];

        [player.viewremoveFromSuperview];

        [playerrelease];

    }

 

2 MediaPlayer播放过程中的事件捕获和处理

本次举例侦听

 // 注册一个播放结束的通知  

 [[NSNotificationCenter defaultCenter] addObserver:self   selector:@selector(myMovieFinishedCallback:)    name:MPMoviePlayerPlaybackDidFinishNotification   object:movie]; 

//处理事件

 

 	/* 
 	 @method 当视频播放完毕释放对象　 
	*/  
 -(void)myMovieFinishedCallback:(NSNotification*)notify  
 {  
    //视频播放对象  
    MPMoviePlayerController* theMovie = [notify object];  
	    //销毁播放通知  
    [[NSNotificationCenter defaultCenter] removeObserver:self  
                                                    name:MPMoviePlayerPlaybackDidFinishNotification  
		                                                  object:theMovie];  
	    [theMovie.view removeFromSuperview];  
	   // 释放视频对象  
    [theMovie release];  
	}
