#import <UIKit/UIKit.h>

#import "AppDelegate.h"

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

错误是

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

线程1：信号SIGABRT

感谢

这是视图controller.h

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

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

- (IBAction)boom:(id)sender;


@end

这是视图controller.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

这是我的代码与该线程1错误!!

Answer 1

您需要做的是找到构建阶段，然后点击+并添加audio.framework 然后尝试run and build，一切都应该是好的。

Answer 2

您需要设置异常断点。见"Run > Stop on Objective-C exception" in Xcode 4?。如果您没有异常断点并且发生异常，那么您将看到的只是一个没有堆栈的SIGABRT，因此您无法找到真正发生的事情。
