【已解决】OS X下AVPlayer播放mp3没有声音

遇到一个问题，新建一个工程，运行以下代码，可以正常运行，但没有声音。

#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
@interface ViewController ()

@property AVPlayer *player;
@property Float64 duration;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Do any additional setup after loading the view.
}

- (IBAction)btn_player:(id)sender {
    NSURL* url = [NSURL fileURLWithPath:@"/Users/ben_gao/Desktop/1.mp3"];
    if(!_player){
        NSLog(@"initialize...");
        _player = [[AVPlayer alloc] initWithURL:url];
    }
    [_player play];
}


- (void)setRepresentedObject:(id)representedObject {
    [super setRepresentedObject:representedObject];

    // Update the view, if already loaded.
}


@end

解决方案：关闭工程的SandBox选项。
