ios - 推送通知操作未在Swift中显示？

我目前有一个iOS项目，但未显示推送通知操作。这是我正在测试的有效载荷主体:

$body['aps'] = array(
  'alert' => $message,
  'sound' => 'default',
  'link_url' => $url,
  'category' => 'NEWS_CATEGORY',
  );

这是App委托中的registerForPushNotifications:

 func registerForPushNotifications(application: UIApplication) {

    //allows notification actions by setting catagories
    let viewAction = UIMutableUserNotificationAction()
    viewAction.identifier = "VIEW_IDENTIFIER"
    viewAction.title = "View"
    viewAction.activationMode = .Foreground

    let newsCategory = UIMutableUserNotificationCategory()
    newsCategory.identifier = "NEWS_CATEGORY"
    newsCategory.setActions([viewAction], forContext: .Default)

    let notificationSettings = UIUserNotificationSettings(forTypes: [.Badge, .Sound, .Alert], categories: [newsCategory])
  }

我们非常感谢您对为何未显示通知操作的任何帮助!

最佳答案

似乎忘记了向应用程序实际添加注册设置。加

application.registerUserNotificationSettings(notificationSettings)

let notificationSettings = UIUserNotificationSettings(forTypes: [.Badge, .Sound, .Alert], categories: [newsCategory])之后
