这是代码：

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

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

这是什么标记：

返回UIApplicationMain(argc,NSStringFromClass([AppDelegate class]));

请说明我做错了什么

解决方法

正如我们在评论中讨论的,问题在于您的NIB配置.视图控制器的根视图正在使用自定义类WelcomeUI,它不是UIView的子类.当试图设置其视图时,视图控制器加载了成功初始化了WelcomeUI实例的NIB,但是当它尝试执行选择器_setViewDelegate时会崩溃：因为它不是视图.

要解决此问题,您只需要进入Interface Builder,展开视图控制器以选择视图(在侧栏中可能显示为“WelcomeUI”),打开身份检查器并删除自定义类.

由于您打算设置视图控制器的自定义类,您可以在左侧栏中选择视图控制器本身,并将其自定义类设置为“WelcomeUI”.
