body: <p>I have an array of <code>NSNumber</code>s, for example: 10015, 12313, 10016</p>
  
  <p>I want to check if the array contains the integer I've entered in the searchBar.</p>

  <pre><code>NSPredicate *resultPredicate = [NSPredicate 
      predicateWithFormat:@"SELF CONTAINS[c] %d", [searchText intValue]];
  
  
  self.searchResults = [newArr filteredArrayUsingPredicate:resultPredicate];
