How to implement "check for updates" concept in iphone app
<p>I have pickerview which is showing times in minuts like (5,10,20). If user will select any of the time he will get updates after selected time. And my application will run as usual but after 5 minutes a message will show some updates occured.</p>

<p>How I will implement this concept? What coding should I do?</p>

<p>As per my guess should I go with threading?</p>
