UITextfield and webservice
<p>I have one query regarding the (UITextfield and Webservice) for example</p>

<p>When i start writing text in UITextfield. Make sure, the app does not query the server(Webservice) for each letter typed. It should wait till I make a pause and then send the request.</p>

<p>Is this possible to when using of UITextField?</p>

<p>Thanks in advance </p>
