xcode 4.2 soundboard thread 1

안녕하세요, Xcode 사운드 보드를 만들었지 만 iPhone을 실행하면이 오류가 발생하고 해결 방법을 알 수 없습니까? 신호 SIGABRTxcode 4.2 soundboard thread 1

THANKS

는이 뷰 컨트롤러 인

#import <UIKit/UIKit.h> 
#import <AudioToolbox/AudioToolbox.h> 

@interface ViewController : UIViewController 
- (IBAction)yooo:(id)sender; 

- (IBAction)boom:(id)sender; 


@end

뷰 controller.h이다

int main(int argc, char *argv[]) 
{ 
    @autoreleasepool { 
     return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); 
    } 
}

오류가

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

스레드 1은 .m

- (IBAction)yooo:(id)sender { 

    CFBundleRef mainbundle = CFBundleGetMainBundle(); 
    CFURLRef soundFileUrlRef; 
    soundFileUrlRef = CFBundleCopyResourceURL(mainbundle, (CFStringRef) @"tb1", CFSTR ("wav"), NULL); 
    UInt32 soundID; 
    AudioServicesCreateSystemSoundID(soundFileUrlRef, &soundID); 
    AudioServicesPlaySystemSound(soundID);} 

- (IBAction)boom:(id)sender { 


    CFBundleRef mainbundle = CFBundleGetMainBundle(); 
    CFURLRef soundFileUrlRef; 
    soundFileUrlRef = CFBundleCopyResourceURL(mainbundle, (CFStringRef) @"ta1", CFSTR ("wav"), NULL); 
    UInt32 soundID; 
    AudioServicesCreateSystemSoundID(soundFileUrlRef, &soundID); 
    AudioServicesPlaySystemSound(soundID); 
} 


@end
