在ios 11中从本地通知打开视图控制器

import UserNotifications

// 创建本地通知
let content = UNMutableNotificationContent()
content.title = "通知标题"
content.body = "通知内容"
content.categoryIdentifier = "myCategory"
content.userInfo = ["viewController": "MyViewController"]

let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
let request = UNNotificationRequest(identifier: "myNotification", content: content, trigger: trigger)

// 注册通知
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
    if granted {
        UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
    }
}

// 处理通知点击
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        UNUserNotificationCenter.current().delegate = self
        return true
    }
    
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        if response.actionIdentifier == UNNotificationDefaultActionIdentifier {
            let userInfo = response.notification.request.content.userInfo
            if let viewControllerName = userInfo["viewController"] as? String {
                // 根据viewControllerName创建并展示对应的视图控制器
                let viewController = MyViewController()
                // 使用导航控制器展示
                let navigationController = UINavigationController(rootViewController: viewController)
                window?.rootViewController?.present(navigationController, animated: true, completion: nil)
            }
        }
        completionHandler()
    }
}
