在 ios 10 中有 UNUserNotificationCenter 类和方法 getNotificationSettingsWithCompletionHandler 为您提供 UNNotificationSettings 对象，您可以检查用户是否曾被要求提供推送通知权限。有没有办法在 iOS 9 和iOS 8。

【解决方案1】：

你可以这样使用：

let notificationType = UIApplication.sharedApplication().currentUserNotificationSettings()!.types

if notificationType == UIUserNotificationType.None {
  // Push notifications are disabled in setting by user.
} else {
 // Push notifications are enabled in setting by user.
}

if notificationType != UIUserNotificationType.None {
  // Push notifications are enabled in setting by user.
}

if notificationType == UIUserNotificationType.Badge {
  // the application may badge its icon upon a notification being received
}

if notificationType == UIUserNotificationType.Sound {
  // the application may play a sound upon a notification being received
}

if notificationType == UIUserNotificationType.Alert {
  // the application may display an alert upon a notification being received
}
