处理应用程序死亡时的通知操作iOS 10

Question

我在应用程序上处理iOS的本地和远程通知，并且即时通讯面临一个问题。当应用程序被终止并且通知到达远程或本地时，我点击通知，然后调用didFinishLaunchingWithOptions被调用并打开应用程序。但是，如果我选择自定义操作而不是点击通知，我的应用程序会崩溃。

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

setActions() 
if #available(iOS 10.0, *) { 
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.badge,.sound], completionHandler: {(granted,error) in 
     if granted{ 
      print("Notification access granted") 
     } 
     else 
     { 
      print(error?.localizedDescription as Any) 
     } 
    }) 
} 
else { 
    // Fallback on earlier versions 
} 

if #available(iOS 10.0, *) { 
    UNUserNotificationCenter.current().delegate = self 
} else { 
    // Fallback on earlier versions 
} 
registerForPushNotifications(application: application) 

if let notification = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? [String: AnyObject] 
{ 
self.application(application, didReceiveRemoteNotification: notification) 
} 

return true 
} 


func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) { 
let aps = data["aps"] as! [String:AnyObject] 
let alert = aps["alert"] as! [String:AnyObject] 
let title = alert["title"] as! String 
let deadlineTime = DispatchTime.now() + .milliseconds(10) 
DispatchQueue.main.asyncAfter(deadline: deadlineTime) { 
     let navigationController = self.window?.rootViewController as! UINavigationController 
     let activeViewCont = navigationController.viewControllers 
     let viewController = activeViewCont[0] as? ViewController 
     viewController?.button.setTitle(title, for: .normal) 

} 
print("Push notification received: \(data)") 
} 


func setActions(){ 

    if #available(iOS 10.0, *) { 

     let like = UNNotificationAction(identifier: "like", title: "Like", options: .foreground) 

     let dismiss = UNNotificationAction(identifier: "dismiss", title: "Dismiss", options: .destructive) 


     //Action for CHAT REPLY 
     let reply = UNTextInputNotificationAction(identifier: "reply", title: "Reply", options: .foreground, textInputButtonTitle: "Send", textInputPlaceholder: "Enter Your Message") 

     let categoryOne = UNNotificationCategory(identifier: "customNotification", actions: [like,dismiss,reply], intentIdentifiers: [], options: []) 
     let categoryTwo = UNNotificationCategory(identifier: "localNotification", actions: [like,dismiss], intentIdentifiers: [], options: []) 

     UNUserNotificationCenter.current().setNotificationCategories([categoryOne,categoryTwo]) 
    } 
    else 
    { 
     let like = UIMutableUserNotificationAction() 

     like.activationMode = .foreground 
     like.identifier = "like" 
     like.title = "Like" 


     let dismiss = UIMutableUserNotificationAction() 
     dismiss.activationMode = .background 
     dismiss.identifier = "dismiss" 
     dismiss.title = "Dismiss" 

     let reply = UIMutableUserNotificationAction() 
     reply.activationMode = .background 
     reply.identifier = "reply" 
     reply.title = "Reply" 
     if #available(iOS 9.0, *) { 
      reply.behavior = .textInput 
     } else { 
      // Fallback on earlier versions 
     } 

     let categoryOne = UIMutableUserNotificationCategory() 
     categoryOne.identifier = "customNotification" 
     categoryOne.setActions([dismiss,like,reply], for: .default) 

     let categoryTwo = UIMutableUserNotificationCategory() 
     categoryTwo.identifier = "localNotification" 
     categoryTwo.setActions([dismiss], for: .default) 

     let notificationSettings = UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: [categoryOne,categoryTwo]) 

     UIApplication.shared.registerUserNotificationSettings(notificationSettings) 
    } 
}

在调度队列中使用此代码。

let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil) 
var homeViewController = mainStoryboard.instantiateViewControllerWithIdentifier("HomeViewController") as! HomeViewController 
let nav = UINavigationController(rootViewController: homeViewController) 
appdelegate.window!.rootViewController = nav
