title: How to search for locations using UISearchBar with autocompletion and suggestions?
body: <p>I am developing an app in which user can search for a point of interests, pick a search result and then the MKMapView will be centered to the result coordinate. </p>
  
  <p>My question is how to make autocompletion happen? I have did research on  <code>MKLocalSearch</code> and <code>MKLocalSearchRequest</code>, and it seems that is Apple suggested API for location search on iOS6.1+. However I cannot find any examples with autocompletion or suggestions with <code>MKLocalSearch</code> and <code>MKLocalSearchRequest</code>. Is it possible to autocomplete a location search or display a list of suggestions just like Apple's Maps app? Thanks!</p>
