Detecting Push Notification enabled with UIBackgroundModes configured in Info.plist

Question

this is my question:

I implemented this code for detected is user enabled or not Push Notification

if ([[UIApplication sharedApplication] isRegisteredForRemoteNotifications]) {
  NSLog(@"Yes, s(he) accepted Push Notification");
} else {
  NSLog(@"No, s(he) rejected Push Notification");
}

which, it works very well. But I had to implemented to receive silent Push Notification in background, so I added this code in my Info.plist

<key>UIBackgroundModes</key>
<array>
  <string>remote-notification</string>
</array>

Then, when I added this, the code that detected if user enabled or not Push notification always return TRUE, it doesn't matter if user enabled or not Push Notification. There is any way to detect only if the user enabled visible Push Notification (alerts in the top of the phone), allowing the UIBackgroundModes?

Answer 1

Is not [[UIApplication sharedApplication] isRegisteredForRemoteNotifications] correct to use. To know the decision of the user about Push notification is with currentUserNotificationSettings

UIUserNotificationSettings *notificationSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];

if (!notificationSettings || (notificationSettings.types == UIUserNotificationTypeNone)) {
      isEnabled = NO;
} else {
      isEnabled = YES;
}
