title: Search ABAddressbook iOS SDK
body: <p>I want to search the iPhone address book for a specific phone number, and then retrieve the contact name. I am currently looping through all contacts and extracting the multivalue properties and comparing against the value. This is taking way too much time. I have read the Apple addressbook guide, and they say:</p>
  
  <blockquote>
    <p>"accomplish other kinds of searches, use the function
    ABAddressBookCopyArrayOfAllPeople and then filter the results using
    the NSArray method filteredArrayUsingPredicate:."</p>
  </blockquote>
  
  <p>Can anyone give me an example on how to exactly do that?</p>
  
  <p>Thanks.</p>
