iPhone GPS CLLocation lock?
<p>How do I go about in an iPhone app, getting the user to click a button to find their location, with the CLLocation automatically locking or stopping when a good enough results is found after a few seconds?</p>

<p>Is there a function or an algorithm?</p>

<p>ie: if it finds a location with accuracy of 5m, stop, or stop after 15 seconds of trying.</p>
