单击模拟器中的开关时出现SIGABRT错误

Question

我一直在研究iPhone应用程序Cruzia，并且想知道为什么每当我点击我游戏的选项菜单中的一个开关时，我在模拟器中出现这个SIGABRT错误的原因。这是我的15个主文件，错误已注释掉。

#import <UIKit/UIKit.h>

#import "CIAAppDelegate.h"

int main(int argc, char *argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([CIAAppDelegate class]));
//Thread 1: signal SIGABRT
    }
}

供参考，这是我的ViewController.m

#import "CIAViewController.h"

@interface CIAViewController()


@end
