Question

- (void)play {

NSString *path = [imgPath path];
NSData *data = [[NSFileManager defaultManager] contentsAtPath:path];
NSLog(#"%#",data);
NSError *error;
self.avPlayer = [[AVAudioPlayer alloc] initWithData:data error:&error];
[self.avPlayer play];
}

Answer 1

Rather then converting into NSData, you can pass URL to AVAudioPlayer.
NSURL *imgPath = [[NSBundle mainBundle] URLForResource:#"sound" withExtension:#"mp3"];
NSError *error;
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:imgPath
error:&error];
self.player.numberOfLoops = 0; //Infinite
self.player.delegate = self;
[self.player prepareToPlay];
[self.player play];

Answer 2

Your code works fine. The problem is while you try to Log the Data.
Or else try with initWithContentsOfURL method.
#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
#interface ViewController ()
#property (nonatomic, strong) AVAudioPlayer *avPlayer;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSURL *imgPath = [[NSBundle mainBundle] URLForResource:#"1" withExtension:#"mp3"];
NSString *path = [imgPath path];
NSData *data = [[NSFileManager defaultManager] contentsAtPath:path];
// NSLog(#"%#",data);
NSError *error;
self.avPlayer = [[AVAudioPlayer alloc] initWithData:data error:&error];
// self.avPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:imgPath error:&error];
[self.avPlayer play];
}
