title: Search for square brackets in NSString
body: <p>I have some text loaded into NSString objects which contains annotations in square brackets - I need to strip the square brackets and everything within them so the user is only presented with the body text.</p>
  
  <p>However, because of the reliance of Objective-C on square brackets for messaging etc..., I'm having a bit of a problem removing them. </p>
  
  <p>Is there some special escape character for using square brackets (for example as an argument to 'rangeOfString:')? Xcode repeatedly informs me that there isn't.</p>
  
  <p>Cheers</p>
