Question

我正在尝试播放声音，当我点击一个按钮，声音片段是10秒，应用程序运行正常，当我点击按钮没有任何反应没有错误或没有，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，我已按照这些步骤进行操作

以下是简单的代码： -

  - (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!");
}
   }

单击按钮时没有声音
