iphone - 单击模拟器中的开关时出现 SIGABRT 错误

Question

我一直在开发 iPhone 应用程序 Cruzia，想知道是否有人知道为什么每当我单击游戏选项菜单中的一个开关时，我会在模拟器中收到此 SIGABRT 错误。这是我的 15 个主文件，错误已被注释掉。

#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
    }
}

作为参考，这是我的 ViewController.m

#import "CIAViewController.h"

@interface CIAViewController()


@end

@implementation CIAViewController
