title: How to get an array of sentences using CFStringTokenizer?
body: <p>I've created an string tokenizer like this:</p>
  
  <pre><code>stringTokenizer = CFStringTokenizerCreate(
                           NULL
                           , (CFStringRef)str
                           , CFRangeMake(0, [str length])
                           , kCFStringTokenizerUnitSentence
                           , userLocale);
  </code></pre>
  
  <p>But how do I obtain those sentences now from the tokenizer? The CF String Programming Guide doesn't mention <code>CFStringTokenizer</code> or tokens (did a full-text search in the PDF).</p>
