一，工程圖。

二，代碼。

RootViewController.h

#import <UIKit/UIKit.h>
//加入AVFoundation.framework頭文件
#import <AVFoundation/AVFoundation.h>

@interface RootViewController : UIViewController
<AVAudioPlayerDelegate>
{
    //播放器player
    AVAudioPlayer *avAudioPlayer;
}

@end

RootViewController.m

#import "RootViewController.h"

//導入AVFoundation.framework
#import <AVFoundation/AVFoundation.h>



@interface RootViewController ()

@end

@implementation RootViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    
    self.title=@"MP3的播放";
}

-(void)initPlay
{
    //從budle路徑下讀取音頻文件
    NSString *string = [[NSBundle mainBundle] pathForResource:@"母親" ofType:@"mp3"];
    
    //把音頻文件轉換成url格式
    NSURL *url = [NSURL fileURLWithPath:string];
    
    //初始化音頻類 並且添加播放文件
    avAudioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
    
    //開始進行播放
    [avAudioPlayer play];
