AppDelegate.h 错误 - XCode [英] AppDelegate.h errors - XCode

问题描述

这真的很奇怪.今天从学校回来并启动我的 Mac Mini 时，我打开了 Xcode，在我的 AppDelegate.h 文件中出现了两个错误.这些错误之一是Expected selector for Objective-C method，另一个是Expected method body.我在谷歌上搜索了这两个错误，但没有发现可以解决我的情况.我试过重新启动 Xcode 和我的电脑.我也尝试过清理"项目，但我的问题仍未解决.这个错误可能是什么?是在我的尽头吗?或者这是一个Xcode错误?谢谢:

This is really weird. When coming back from school today and firing up my Mac Mini, I open up Xcode and I am presented with two errors in my AppDelegate.h file. One of these errors says Expected selector for Objective-C method and the other one is Expected method body. I googled these two errors and found nothing that could solve my case. I have tried restarting Xcode and as well as my computer. I have also tried "Cleaning" the project and still my problem is not resolved. What could this error be? Is it on my end? Or is this an Xcode bug? Thanks:

代码:AppDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window; 

@property (strong, nonatomic) UINavigationController *navigationController;

@end

推荐答案

检查您的 main.m 文件是否有任何额外或不可见的代码:

Check Your main.m File for any extra or invisible Code:

//
//  main.m
//  Demo
//
//  Created by Stackoverflow on 12/20/12.
//
//

#import <UIKit/UIKit.h>

#import "AppDelegate.h" 

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