iPhone Google Maps Component is a component that you can add to your iPhone application to access all basic features of Google Maps (similar to Android’s MapView). It uses a UIWebView in the background to load the HTML/Javascript version of Google Maps, and offers a set of Objective-C methods that mimic a subset of the original Javascript methods for controlling the map. It currently supports setting the center location, and zooming & panning using the touch interface.
