如何在swift 4上从didFinishLaunchingWithOptions获取通知中心数据

// 注册远程通知
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
    if granted {
        DispatchQueue.main.async {
            UIApplication.shared.registerForRemoteNotifications()
        }
    }
}

// 实现UNUserNotificationCenterDelegate协议的didReceive方法
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    // 获取通知的内容和附加信息
    let content = response.notification.request.content
    let userInfo = content.userInfo
    
    // 处理通知数据
    // ...
    
    completionHandler()
}

// 在didFinishLaunchingWithOptions方法中获取通知数据
if let notification = launchOptions?[.remoteNotification] as? [String: AnyObject] {
    // 获取通知的内容和附加信息
    let content = UNNotificationContent(userInfo: notification)
    let userInfo = content.userInfo
    
    // 处理通知数据
    // ...
}
