當我嘗試使用Finch庫for iPhone SDK播放聲音時，爲什麼我的應用程序崩潰？

Question

我完全按照閱讀我文件中的說明操作，但由於某種原因，在我的應用程序中，每當我點擊與代碼相對應的UIButton來播放聲音時[[soundA play];該應用程序只是崩潰而沒有任何詳細的錯誤除了lldb之外，我使用的是Finch，因爲它使用OpenAL播放音頻，我需要使用OpenAL作爲我製作的應用程序的類型，因爲AVAudioPlayer或System Sounds不適用於我正在製作的內容。我使用的代碼

主文件：

#import "ViewController.h" 

@interface ViewController() 

@end 

@implementation ViewController 

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
// Do any additional setup after loading the view, typically from a nib. 
soundFactory = [[FIFactory alloc] init]; 
engine = [soundFactory buildSoundEngine]; 
[engine activateAudioSessionWithCategory:AVAudioSessionCategoryPlayback]; 
[engine openAudioDevice]; 
soundA = [soundFactory loadSoundNamed:@"1.caf" maxPolyphony:16 error:NULL]; 
soundB = [soundFactory loadSoundNamed:@"2.caf" maxPolyphony:16 error:NULL]; 
soundC = [soundFactory loadSoundNamed:@"3.caf" maxPolyphony:16 error:NULL]; 
soundD = [soundFactory loadSoundNamed:@"4.caf" maxPolyphony:16 error:NULL]; 
} 

- (void)viewDidUnload 
{ 
[super viewDidUnload]; 
// Release any retained subviews of the main view. 
} 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{ 
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { 
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); 
} else { 
    return YES; 
} 
} 
- (IBAction) PlaySoundA {[soundA play];} 
- (IBAction) PlaySoundB {[soundB play];} 
- (IBAction) PlaySoundC {[soundC play];} 
- (IBAction) PlaySoundD {[soundD play];} 

@end 

頭文件：

#import <UIKit/UIKit.h> 
#import "FISoundEngine.h" 
#import "FIFactory.h" 
#import "FISound.h" 

@interface ViewController : UIViewController { 
FIFactory* soundFactory; 
FISoundEngine* engine; 
FISound* soundA; 
FISound* soundB; 
FISound* soundC; 
FISound* soundD; 
} 

@end 

任何幫助，將不勝感激！謝謝！

聲音播放器很可能找不到您的聲音文件。嘗試右擊音頻文件並選擇查找器中的視圖。確保該文件實際上在您的項目目錄中，而不是
