ios - 显示提醒(警报)，例如自定义警报，并在 IOS 中对该警报执行用户操作

Question

我想在特定时间向用户显示提醒警报。并对该警报 View 执行操作。我使用本地通知来显示提醒，但当应用程序在后台运行时它会显示角标(Badge)样式的消息。为此，我需要替代解决方案。 提前谢谢你...

在AppDelegate中你应该这样写(这是来 self 的应用程序，只是一个例子，根据你的应用程序使用这段代码)

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    let completeAction = UIMutableUserNotificationAction()
    completeAction.identifier = "COMPLETE_TODO" // the unique identifier for this action
    completeAction.title = "Complete" // title for the action button
    completeAction.activationMode = .Background // UIUserNotificationActivationMode.Background - don't bring app to foreground
    completeAction.authenticationRequired = false // don't require unlocking before performing action
    completeAction.destructive = true // display action in red

    let remindAction = UIMutableUserNotificationAction()
    remindAction.identifier = "REMIND"
    remindAction.title = "Remind in 30 minutes"
    remindAction.activationMode = .Background
    remindAction.destructive = false

    let todoCategory = UIMutableUserNotificationCategory() // notification categories allow us to create groups of actions that we can associate with a notification
    todoCategory.identifier = "TODO_CATEGORY"
    todoCategory.setActions([remindAction, completeAction], forContext: .Default) // UIUserNotificationActionContext.Default (4 actions max)
    todoCategory.setActions([completeAction, remindAction], forContext: .Minimal) // UIUserNotificationActionContext.Minimal - for when space is limited (2 actions max)

    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert | .Badge | .Sound, categories: NSSet(array: [todoCategory]))) // we're now providing a set containing our category as an argument
    return true
  }
