title: UISearchBar puts full stop after adding more than one space
body: <p>I am getting strange behaviour from UISearchBar. When I press more that one space in UISearchBar, it automatically puts full stop "." in search bar text. I do not understand why this is happening. Here is my code,</p>
  
  <pre><code> NSString *str = [searchBar.text stringByTrimmingCharactersInSet:
                   [NSCharacterSet whitespaceAndNewlineCharacterSet]];
  
  
  NSLog(@"%@",searchBar.text );
  </code></pre>
  
  <p>I press space and then f and then 2 times space and it puts full stop. Please help me.
  Thanks in advance.</p>
