单击按钮时无声音

Question

当我单击按钮时，我尝试播放声音，声音剪辑为10秒，应用程序运行良好，当我单击按钮时，什么也没有发生，没有错误或什么都没有，这是我的代码

.m file
#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
- (IBAction)Play:(id)sender {

    AVAudioPlayer *audioPlayer;
    NSString *audioPath = [[NSBundle mainBundle]pathForResource:@"Blesgaes" ofType:@"mp3"];
    NSURL *audioURL =[NSURL fileURLWithPath:audioPath];
    audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:nil];
    [audioPlayer play];
}
.h file
#import <AVFoundation/AVFoundation.h>


@interface ViewController : UIViewController
- (IBAction)Play:(id)sender;

我添加了AVFoundation框架，并且按照以下步骤操作

下面是简单的代码：

  - (IBAction)playAudio:(id)sender {
   AVAudioPlayer *audioPlayer;
   NSString *audioPath = [[NSBundle 
    mainBundle] pathForResource:@"Woof" 
    ofType:@"mp3"];
  NSURL *audioURL = [NSURL 
  fileURLWithPath:audioPath];
NSError *audioError = [[NSError alloc] init];
audioPlayer = [[AVAudioPlayer alloc]    
 initWithContentsOfURL:audioURL 
 error:&audioError];

   if (!audioError) {
    [audioPlayer play];
    NSLog(@"Woof!");
}
else {
    NSLog(@"Error!");
}
   }
