本人小白，运行后ios模拟器弹出这个界面是怎么回事啊

#import <UIKit/UIKit.h>#import "AppDelegate.h"int main(int argc, char * argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}
中间还有一行小字thread 1:signal SIGABRT
求解怎么办

    第一步：打开调试窗口：在xcode软件右上方单击倒数第二个按钮，在编辑器的下方显示all output小窗口
    第二步：在调试窗口中将异常信息复制出来，然后跟贴
    第三步：要根据你的错误信息进行问题诊断
