Swift:网络请求在AppStart in AppDelegate - CompletionHandler in ViewController？

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // 发起网络请求
    NetworkManager.shared.makeRequest { result in
        // 将结果传递给ViewController
        NotificationCenter.default.post(name: Notification.Name("NetworkRequestCompleted"), object: result)
    }
    return true
}

override func viewDidLoad() {
    super.viewDidLoad()
    
    // 监听网络请求完成的通知
    NotificationCenter.default.addObserver(self, selector: #selector(handleNetworkRequestCompleted(_:)), name: Notification.Name("NetworkRequestCompleted"), object: nil)
}

@objc func handleNetworkRequestCompleted(_ notification: Notification) {
    if let result = notification.object as? NetworkResult {
        // 处理网络请求结果
        // 更新UI或执行其他操作
    }
}
