title: Autocomplete textfield in ios
body: <p>I am working in <code>Xcode 6.4</code>(Objective C). I have an array of names.I want to autocomplete my <code>textfield</code> while user enter something.If user enters "a" in <code>TextField</code>, a dropdown with all names which start from "a"  must be shown.Like that if user enters "ab" in <code>TextField</code>, a dropdown with all names which start from "ab"  must be shown.</p>
  
  <p>I know a <code>TableView</code> is needed for dropdown.I tried some examples by searching SO and other sites(RayWendelich.com). But i couldn't solve this issue.Please help me with a simple solution.(I am new to the iOS development).</p>
