當按鈕點擊時沒有聲音

Question

我試圖播放聲音，當我點擊一個按鈕，聲音剪輯是10秒，應用程序運行良好，當我點擊按鈕沒有任何事情發生沒有錯誤或沒有任何東西，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; 

我已經添加AVFoundation框架，我按照這些步驟

下面是簡單的代碼： - 按鈕（IBAction爲）之間

- (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!"); 
} 
    }
