ios - 滑动本地通知以加载 ui 警报 View

Question

我编写了以下通知代码

let notification = UILocalNotification()
notification.fireDate = NSDate(timeIntervalSinceNow: 5)
notification.alertBody = "Do you want to extend your checkout time
notification.alertAction = "to view"
notification.soundName = UILocalNotificationDefaultSoundName
notification.userInfo = ["isExtendCheckOutTime": "true"]

UIApplication.sharedApplication().scheduleLocalNotification(notification)

通知显示得很好，但是当我滑动时，我想加载 UIAlertViewController 并执行一些任务。

我对 swift 完全陌生，想知道我应该在哪里编写代码以获得所需的行为。我在应用程序委托(delegate)中尝试过但没有成功。

如果我没记错的话，只有当你点击actionButton时才有可能。这样你必须添加

func application(application: UIApplication, handleActionWithIdentifier     identifier: String?, forLocalNotification notification:  UILocalNotification, completionHandler: () -> Void) {
    if identifier == "CANCEL_ACTION" {
        NSNotificationCenter.defaultCenter().postNotificationName("actionCancelPressed", object: nil)
    }

    completionHandler()
}

到AppDelegate。

并将类别与 UIUserNotificationAction 一起使用。喜欢:

    let cancelAction1 = UIMutableUserNotificationAction()
    cancelAction1.identifier = "CANCEL_ACTION"
    cancelAction1.title = "cancel"

    let cancelAction2 = UIMutableUserNotificationAction()
    cancelAction2.identifier = "CANCEL_ACTION"
    cancelAction2.title = "cancel"
    cancelAction2.activationMode = .Background
    cancelAction2.destructive = true
    cancelAction2.authenticationRequired = false

    let openAction = UIMutableUserNotificationAction()
    openAction.identifier = "OPEN_ACTION"
    openAction.title = "open"

    let actions1 = [cancelAction1, openAction]
    let actions2 = [cancelAction2, openAction]

    let firstCategory = UIMutableUserNotificationCategory()
    firstCategory.identifier = "FIRST_CATEGORY"
    firstCategory.setActions(actions1, forContext: .Minimal)

    let secondCategory = UIMutableUserNotificationCategory()
    secondCategory.identifier = "SECOND_CATEGORY"
    secondCategory.setActions(actions2, forContext: .Minimal)

    let set: Set<UIUserNotificationCategory> = [firstCategory, secondCategory]

    let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories:set)
    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)

然后

notification.category = "FIRST_CATEGORY"

否则你必须自己捕捉这个 Action 。但我可能是错的!)
