Is the visibleRect method also available on iPhone? How do I find it out?
<p>Apple says that there is a visibleRect method on the mac (<a href="http://developer.apple.com/documentation/Cocoa/Conceptual/CocoaViewsGuide/Coordinates/Coordinates.html" rel="nofollow">Source</a>), that helps doing graphic operations only in the visible content rectangle from an view.</p>

<p>When I try to access that method, XCode gives me no completion hint, so it seems that this one is not available on iPhone. How could I find that out?</p>
