【中文标题】显示提醒（警报），如自定义警报并在 IOS 中对该警报执行用户操作

【英文标题】：Show reminder(alarm) like custom alert and perform user action on that alert in IOS

【问题描述】：

我想在特定时间向用户显示提醒警报。并对该警报视图执行操作。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徽章样式消息。我需要替代解决方案。 提前谢谢你...

【参考方案1】：

在AppDelegate中你应该这样写（这是我的应用，只是一个例子，根据你的应用使用这个代码）

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

感谢您的回复，我使用了此代码，但是当我单击“完成”操作应用程序时无法打开（确实收到本地通知呼叫）...

感谢您的回答 ....一个问题是有没有其他方式显示提醒（警报），如自定义警报，并在没有本地通知的情况下对该警报执行用户操作。
