ios - 当点击本地通知 Swift 时呈现一个特定的 VC

Question

我尝试在其他帖子中针对同一问题遵循各种解决方案，但似乎没有一个适用于我的代码。我将警报合并到我的应用程序中，我的目标是让NewMapViewController用户点击警报本地通知和呼叫checkAlerts2()功能，通过应用程序菜单访问该 VC 时通常不会调用该功能。谢谢你一如既往的帮助。这是我的 AppDelegate：

import UIKit
import CoreData
import Foundation
import AudioToolbox
import AVFoundation
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,AVAudioPlayerDelegate, AlarmApplicationDelegate {

    var window: UIWindow?
    var audioPlayer: AVAudioPlayer?
    let alarmScheduler: AlarmSchedulerDelegate = Scheduler()
    var alarmModel: Alarms = Alarms()


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        var error: NSError?
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        } catch let error1 as NSError{
            error = error1
            print("could not set session. err:\(error!.localizedDescription)")
        }
        do {
            try AVAudioSession.sharedInstance().setActive(true)
        } catch let error1 as NSError{
            error = error1
            print("could not active session. err:\(error!.localizedDescription)")
