IOS 流媒体播放器 源代码

需要导入两个系统库文件CoreMedia.framework 和 AVFoundation.framework，

MediaPlayer-Prefix.pch 文件

#import<Availability.h>

#ifndef __IPHONE_4_0

#warning "This project uses features only available in iOS SDK 4.0 and later."

#endif

#ifdef __OBJC__

    #import<UIKit/UIKit.h>

    #import<Foundation/Foundation.h>

   //在预编译头文件中导入头文件A相当于在每个.m中导入该头文件A 因为基本上每个.m文件中都要用到

    #import<AVFoundation/AVFoundation.h>

#endif

注意：将 ViewController.xib 要关联的类设置为WJPlayView，操作在之前的博客中说过。

ViewController.h 文件

#import<UIKit/UIKit.h>
