当我尝试使用Finch库for iPhone SDK播放声音时，为什么我的应用程序崩溃？

Question

我完全按照阅读我文件中的说明操作，但由于某种原因，在我的应用程序中，每当我点击与代码相对应的UIButton来播放声音时[[soundA play];该应用程序只是崩溃而没有任何详细的错误除了lldb之外，我使用的是Finch，因为它使用OpenAL播放音频，我需要使用OpenAL作为我制作的应用程序的类型，因为AVAudioPlayer或System Sounds不适用于我正在制作的内容。我使用的代码

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 

头文件：

#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 

任何帮助，将不胜感激！谢谢！

声音播放器很可能找不到您的声音文件。尝试右击音频文件并选择查找器中的视图。确保该文件实际上在您的项目目录中，而不是
