Convert NSString (eg: "2300") to NSDate (iOS) : <p>I'm trying to convert an <code>NSString</code> like this one "2300" to <code>NSDate</code> format. (Note: there is no colon after 23).</p>

<p>I get the string from an external web service. I need to display this time in my app in 12hr format.</p>

<p>Thank You :)</p>
