title: Best way to split strings into an array
body: <p>I'm developing a travel app, I have to read a txt file that contains all the states and countries, as you can notice this is a pretty huge file to read, anyway, this is an example of the text inside the file:</p>
  
  <p>Zakinthos (ZTH),GREECE<br>
  Zanesville (ZZV),USA<br>
  Zanjan (JWN),IRAN<br>
  Zanzibar (ZNZ),TANZANIA<br>
  ...</p>
  
  <p>Now i'm reading the file with no problem but I don't know how to create two arrays, one with the state and another with the country so I can show them into a table when text is being autocompleted.</p>
  
  <p>I've tried using NSScanner using the "," as a delimiter but I don't know how to make that works and also I tried with NSString methods with no results. </p>
  
  <p>Any help is welcomed, Thank you in advance!!!.</p>
  
  <p>btw sorry about my english XD</p>
