title: How to store app settings in iOS, like INI / CONF?
body: <p>I am starting with iOS programming. I have a question hope you can help.</p>
  
  <p>I have a test app as an rss reader that reads from a URL.  For example: abc.com/feed</p>
  
  <p>I want to store some data in a setting file like INI on Windows or CONF on Linux, example:</p>
  
  <pre><code>URL = abc.com/feed
  NumberOfItem = 10
  Interval = 3 # minus
  </code></pre>
  
  <p>What kind of file does an iOS app use to store it's settings?  Is there any method/class/API/... which supports read/write on it?</p>
  
  <p>P.S.  I am using <strong>Titanium</strong> at Appcelerator.</p>
  
  <p>Thanks so much!</p>
