Question

运行我的应用程序后，我在AppDelegate.h中收到此错误消息。＆＃34;线程1：信号SIGABRT＆＃34;我已经评论了我的代码侧面发生错误的位置。请有人帮忙吗。谢谢。

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

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

这是我得到的堆栈跟踪：

Game[3599:70b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIApplication 0x109c28520> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key view.'

上述行意味着您正在尝试访问名为view的属性，但您的类没有该名称的属性。要么是在一个实际上没有视图的对象上调用view属性（但这很可能被编译器捕获），要么在Interface Builder中没有为视图控制器设置视图出口。

检查您在App Delegate中加载的视图控制器是否在IB中连接了视图插座。

线程1：信号SIGABRT有人可以帮助我吗？
