swift，UIUserNotificationAction从视图控制器，而不是应用程序委托

Question

我试图从ViewController定义用户通知操作。根据我的理解，必须在应用程序代表中设置通知与操作。

所以here's我的应用程序代表：

class AppDelegate: UIResponder, UIApplicationDelegate { 




enum Actions:String{ 
    case confirmunlock = "CONFIRMUNLOCK_ACTION" 
} 

var categoryID:String { 
    get{ 
     return "CONFRIMUNLOCK_CATEGORY" 
    } 
} 


// Register notification settings 
func registerNotification() { 

    // 1. Create the actions ************************************************** 

    // confirmunlock Action 
    let confirmunlockAction = UIMutableUserNotificationAction() 
    confirmunlockAction.identifier = Actions.confirmunlock.rawValue 
    confirmunlockAction.title = "Öffnen" 
    confirmunlockAction.activationMode = UIUserNotificationActivationMode.Background 
    confirmunlockAction.authenticationRequired = false 
    confirmunlockAction.destructive = false 




    // 2. Create the category *********************************************** 

    // Category 
    let confirmunlockCategory = UIMutableUserNotificationCategory() 
    confirmunlockCategory.identifier = categoryID 

    // A. Set actions for the default context 
    confirmunlockCategory.setActions([confirmunlockAction], 
           forContext: UIUserNotificationActionContext.Default) 

    // B. Set actions for the minimal context 
    confirmunlockCategory.setActions([confirmunlockAction], 
           forContext: UIUserNotificationActionContext.Minimal) 


    // 3. Notification Registration ***************************************** 

    let types: UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Sound] 
    let settings = UIUserNotificationSettings(forTypes: types, categories: NSSet(object: confirmunlockCategory) as? Set<UIUserNotificationCategory>) 
    UIApplication.sharedApplication().registerUserNotificationSettings(settings) 
} 


// MARK: Application Delegate 


func application(application: UIApplication, 
       handleActionWithIdentifier identifier: String?, 
              forLocalNotification notification: UILocalNotification, 
                   completionHandler:() -> Void) { 

    // Handle notification action ***************************************** 
    if notification.category == categoryID { 

     let action:Actions = Actions(rawValue: identifier!)! 

     switch action{ 

     case Actions.confirmunlock: 
      print("Well done!") 

     } 
    } 

    completionHandler() 
} 



var window: UIWindow? 




func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 

    // Override point for customization after application launch. 

    registerNotification() 

    return true 
} 

这种运作良好。当我将“notification.category = categoryID”添加到我的LocalNotifications之一时，它会记录“做得好”。现在我想调用的动作实际上应该从视图控制器中调用。它有很多变量，你必须先登录才能访问服务器以调用操作等。我该怎么做？当我把这个功能放在我的视图控制器中时，动作并没有被调用：

func application(application: UIApplication, 
       handleActionWithIdentifier identifier: String?, 
              forLocalNotification notification: UILocalNotification, 
                   completionHandler:() -> Void) { 

    // Handle notification action ***************************************** 
    if notification.category == categoryID { 

     let action:Actions = Actions(rawValue: identifier!)! 

     switch action{ 

     case Actions.confirmunlock: 
      print("Well done!") 

     } 
    } 

    completionHandler() 
} 

很多谢谢！ Stephan

Answer 1

我知道它与NSNotification一起工作。

NSNotificationCenter.defaultCenter().postNotificationName 

在触发器所在的Appdelegate中。和

NSNotificationCenter.defaultCenter().addObserver 

在我的视图控制器的viewdidload。

最好 斯蒂芬

Answer 2

此功能是UIApplicationDelegate协议的一部分，它由您的AppDelegate实现，它是UIApplication类型的实例。如果您有参考，您可以从此功能中调用您的控制器。
