單擊按鈕時無聲音

Question

當我單擊按鈕時，我嘗試播放聲音，聲音剪輯為10秒，應用程序運行良好，當我單擊按鈕時，什么也沒有發生，沒有錯誤或什么都沒有，這是我的代碼

.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，並且按照以下步驟操作

下面是簡單的代碼：

  - (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!");
}
   }
