检查UILocalNotification弃用后是否启用了用户通知 [英] Check whether user notifications are enabled after UILocalNotification deprecation

问题描述

在我的应用中，我希望能够检查用户是否启用了通知。在iOS 10中，我是使用委托检查的。

In my app, I want to be able to check if the user has notifications enabled or not. In iOS 10, I did this using a check in the delegate.

此检查现已弃用，我想对其进行更新，但我不知道该怎么做。在iOS 11中使用。

This check is now deprecated and I want to update it, but I can't figure out what to use in iOS 11.

弃用警告如下：

currentUserNotificationSettings在iOS 10.0中已弃用：使用
UserNotifications框架的-[UNUserNotificationCenter
getNotificationSettingsWithCompletionHandler：]和
-[UNUserNotificationCenter getNotificationCategoriesWithCompletionHandler：]

currentUserNotificationSettings' was deprecated in iOS 10.0: Use UserNotifications Framework's -[UNUserNotificationCenter getNotificationSettingsWithCompletionHandler:] and -[UNUserNotificationCenter getNotificationCategoriesWithCompletionHandler:]

我试图借助此警告来更新代码，但我无法弄清楚。

I've tried to update the code with the help of this warning but I can't figure it out.

如果有人可以建议无论如何，获得像这样的支票会很有帮助。谢谢，下面是我为iOS 10使用的代码。

If anyone can suggest anyway to get a check like this working it would help a lot. The code I have been using for iOS 10 is below, thanks.

let notificationType = UIApplication.shared.currentUserNotificationSettings!.types
if notificationType == [] {
    print("Notifications are NOT enabled")
} else {
    print("Notifications are enabled")
}

推荐答案

步骤1：导入UserNotifications

步骤2：

UNUserNotificationCenter.current().getNotificationSettings { (settings) in
  if settings.authorizationStatus == .authorized {
    // Notifications are allowed
  }
  else {
    // Either denied or notDetermined
  }
}

检查设置对象以获取更多信息。

Inspect the settings object for more informations.
