title: registerUserNotificationSettings not showing prompt iOS 8
body: <p>I can't seem to get a prompt to show for <code>registerUserNotificationSettings</code> in iOS 8.1 or 8.2. </p>
  
  <p>Here is what I'm doing in <code>didFinishLaunchingWithOptions</code>: </p>
  
  <pre><code>  if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
         #ifdef __IPHONE_8_0
          UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert
                                                                                               |UIUserNotificationTypeSound | UIUserNotificationTypeBadge) categories:nil];
          NSLog(@"Reg settings %@", settings);
          [application registerUserNotificationSettings:settings];
      #endif
      }
  </code></pre>
  
  <p>Also getting the correct call back here: </p>
  
  <pre><code>- (void)application:(UIApplication *)application
  didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{
      NSLog(@"Did register - %@", notificationSettings);
  }
  </code></pre>
  
  <p>Yet no prompt is ever displayed. What's even more annoying is that an alert will display when the device is locked, but won't give the notification alert sound. Any ideas on a work around? </p>
