title: search if NSString contains value
body: <p>I have some string value which constructed from a few characters  , and i want to check if they exist in another NSString, without case sensitive, and spaces .</p>
  
  <p>Example code :</p>
  
  <pre><code>NSString *me = @"toBe" ;
  NSString *target=@"abcdetoBe" ;
  //than check if me is in target.
  </code></pre>
  
  <p>Here i will get <code>true</code> because <code>me</code> exist in <code>target</code> .
  How can i check for such condition ?</p>
