how can i set time delay between two functions in iPhone?
<p>I build app which call to server. </p>

<p>it takes for 20 seconds - 30 seconds to get reply from server, because the system we use depending to outside service (connecting to our partners system).</p>

<p>before i can do the next, i must wait to get results. </p>

<p>is there any way to set the delay time for waiting reply???</p>

<p>thanks in advance</p>
