title: How to split a string into sentences cocoa
body: <p>I have an <code>NSString</code> with a number of sentences, and I'd like to split it into an <code>NSArray</code> of sentences. Has anybody solved this problem before? I found <code>enumerateSubstringsInRange:options:usingBlock:</code> which is able to do it, but it looks like it isn't available on the iPhone (Snow Leopard only). I thought about splitting the string based on periods, but that doesn't seem very robust.</p>
  
  <p>So far my best option seems to be to use RegexKitLite to regex it into an array of sentences. Solutions?</p>
