1. Configure the library--avfoundation.framework

Header file #import <AVFoundation/AVFoundation.h>

2. Play audio (1) Play local audio

@interface Viewcontroller () {  //  avaudioplayer *_player;    UISlider *_volumeslider;  // Volume Control //     uiprogressview *_playprogressview;   // Play Progress  **playprogressview;
