播放音樂誤差和相對尋路

Question

我想在我的應用程序來播放MP3，和一噸的研究後，我仍然無法弄清楚如何做到相對路徑功能，甚至讓音樂絕對尋路打。這是我有：

//set music 
NSError *error; 
if (songChosen == 0) 
{ 
    soundPath = @"/Users/aeubanks/Desktop/XCode Stuff/Apps/Game-Storyboard/Game-Storyboard/Amalgamation.mp3"; 
} 
else if (songChosen == 1) 
{ 
    soundPath = @"/Users/aeubanks/Desktop/XCode Stuff/Apps/Game-Storyboard/Game-Storyboard/BUTTERFLY.mp3"; 
} 
audio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundPath] error:&error]; 
if([[NSFileManager defaultManager] fileExistsAtPath:soundPath] == NO) 
{ 
    NSLog(@"No File"); 
} 

else 
{ 
    NSLog(@"Yes File"); 
} 

if(error != nil) 
{ 
    NSLog(@"%@", error); 
} 
[audio prepareToPlay]; 

的NSLog的說，這（準備）：

我自己也嘗試設置和聲來@ 「BUTTERFLY.mp3」/ @ 「Amalgamation.mp3」 以及@「遊戲-Storyboard/BUTTERFLY.mp3 「/ @」 遊戲情節提要/ Amalgamation.mp3" ，我得到這個：

2012-08-04 15：58：55.763遊戲，故事板[8470：10703]號文件

2012-08-04 15:58:55.767 Game-Storyboard [8470：10703] Error Domain = NSOSStatusErrorDomain Code = -43「操作無法完成。 （OSStatus錯誤-43）」

我不知道這一切意味着，所以我希望得到一些幫助，以解決這一問題

Answer 1

我會做這樣的事情（這裏有一個片段）：

if (songChosen == 0) 
{ 
    NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"Amalgamation" ofType:@"mp3"] 
    NSURL *soundFileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; 
    NSError *error; 
    AVAudioPlayer *aPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:&error]; 
} 

我也建議在束讀了。
