当我尝试使用 iPhone SDK 的 Finch 库播放声音时，为什么我的应用程序会崩溃？

Question

我完全按照自述文件中的说明进行操作，但由于某种原因，在我的应用程序中，每次我点击与代码对应的 UIButton 以播放声音“[soundA play]; 应用程序只是崩溃而没有任何详细信息错误描述，除了 lldb。我使用 Finch，因为它使用 OpenAL 播放音频，并且我需要将 OpenAL 用于我正在制作的应用程序类型，因为 AVAudioPlayer 或系统声音不适用于我正在制作的内容。这里是我正在使用的代码。

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。尝试右键单击音频文件并在查找器中选择视图。确保文件实际上在您的项目目录中，而不是
