title: How to get the name of a contact related to a certain phone number?
body: <p>In my app I receive a json response from the server which contains phone numbers. I wan't to show the full name of the contact if the number is stored in the addressbook. Similar to the phone app when you type in a number manually the iPhone shows the name if the number is stored in the addressbook.</p>
  
  <p>I can't find any tutorial on the web. Probably due to the search string which always contains iphone, number and contact and I get a lot of results but nothing helpful.</p>
  
  <p>Can anybody give me a hint where to look or how to do that?</p>
