在設備上用Objective C播放聲音

Question

我已經看過很多關於這個問題的答案，並且無法找到任何工作。

這裏是我的問題，我想打一個按鈕按下一個聲音，這裏是該文件位於

這裏是我的代碼

- (void)playSoundWithOfThisFile:(NSString*)fileName { 

NSString *soundFilePath = [NSString stringWithFormat:fileName, 
          [[NSBundle mainBundle] resourcePath]]; 
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath]; 

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL 
                   error:nil]; 
player.numberOfLoops = 1; 

[player play]; 

}

當我運行代碼時，數值如下

fileName = Mummy.mp3 

`soundFilePath = Mummy.mp3` (I've had it Sounds/Mummy.mp3 and this doesn't work either) 

soundFileURL = Mummy.mp3 - 文件：///

player = nil 

任何幫助將不勝感激。如果我發現錯誤只是一個通用的錯誤，沒有信息

Answer 1

嘗試

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Mummy" ofType:@"mp3"]; 

NSURL *soundFileURL = [NSURL fileURLWithPath:filePath]; 
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL 
                   error:nil]; 
player.numberOfLoops = 1; 
[player play]; 

文檔使用下面的代碼

SystemSoundID soundID; 
NSString *soundFile = [[NSBundle mainBundle] 
         pathForResource:@"test" ofType:@"mp3"]; 
AudioServicesCreateSystemSoundID((__bridge CFURLRef) 
           [NSURL fileURLWithPath:soundFile], & soundID); 
AudioServicesPlaySystemSound(soundID); 

不要忘了導入

#import <AudioToolbox/AudioToolbox.h> 

Answer 2

試試這個。在pathForResource: ofType:

Answer 3

NSString *path = [[NSBundle mainBundle] pathForResource: @"how_to_play" ofType: @"mp3"]; 
      if(!self.theAudio) 
      { 
       self.theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; 
       self.theAudio.delegate = self; 
       [self.theAudio play]; 
      } 

放於viewcontroller.h

< AVAudioPlayerDelegate> 

@property(nonatomic,strong) AVAudioPlayer *theAudio;
