title: Objective-C: Real-time location updates
body: <p>I wanted to ask is there anyway to communicate the location of someone to another device live? Sort of like GPS or instant messaging.</p>
  
  <p>I know that you can use <code>CLLocationManagerDelegate</code> to update location. Instead of updating to a database like Parse and having the receiving user grab from there, is there a way to send immediately to the receiver? The functionality I am looking for is similar to how you can see yourself move on Google Maps GPS or how you can receive a message instantly in other apps.</p>
  
  <p>Right now I currently am using Google Maps SDK so I would be updating the marker location as soon as the location was updated.</p>
  
  <p>Any suggestions?</p>
