ios音乐播放小demo 第一次未修改，先传上来

---恢复内容开始---

第一次写的未修改，先上传了，以后在修改了，简单的实现了功能，代码不好见谅

 

 

主要步骤：

1.新建一个歌曲类  歌名，歌手，格式。。。。

2，播放界面viewcontroller

3，单元格的tableviewcell

4，视图adioviewcontroller

播放界面的代码

  1 #import "AdioViewController.h"
  2 #import <AVFoundation/AVFoundation.h>
  3 
  4 #import "Song.h"
  5 @interface AdioViewController ()

  7 {
  8     AVAudioPlayer* _avAudioPlay;//播放器player
  9     //UIProgressView* progressV;//播放进度
 10     UISlider* progresslider;
 11     UISlider* volumeSlider;//声音控制
 12     NSTimer* timer;//监控音频播放进度
 13     UIButton* btnAnimation;//播放键
 14     UIButton* abtnAnimation;//暂停键
 15     UIButton* btn2;//单曲循环
 16     UIButton* btn3;//取消单曲循环
 17     UIButton* btn4;//随机播放
 18     UIButton* btn5;//取消随机播放
 19     NSInteger aflag;//设置标示，判断播放模式
