IOS：通知仅显示使用GCM未显示类别的交叉按钮

Question

我正在尝试使用IOS中的UIMutableUserNotificationCategory显示通知，但它只显示默认的十字按钮，而不显示其他按钮然后我在类别中添加。它应该像这样显示出来。 GCM是否可能或不可能。这是我在应用程序didfinishlaunching中添加类别的方法

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

    releaseRoomCategory.setActions([yesAction, noAction],
        forContext: UIUserNotificationActionContext.Minimal)
    releaseRoomCategory.setActions([yesAction, noAction], forContext: .Default)

    let settings: UIUserNotificationSettings =
    UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories:  NSSet(object: releaseRoomCategory) as? Set<UIUserNotificationCategory>)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()

嗨，终于找到了我自己的答案，这就是它为GCM所做的工作

{"to": <reg_token>, "notification": {"body": "Hello from GCM", "click_action": "RELEASEROOM_CATEGORY"}}

click_action代表类别：D感谢每一个：D
