iOS开发----音频、视频的实现

在项目中先把必要的库添加上去！



#import <AVFoundation/AVFoundation.h>

#import <MediaPlayer/MediaPlayer.h>

@interface ViewController :
UIViewController<AVAudioPlayerDelegate>

{

    AVAudioPlayer * avAudioPlayer;//播放器

    //UIProgressView * progressView;//控制播放进度

    MPMoviePlayerViewController * _playerVc;

    

    

    

}

//
