Sample-iphonesdk-tapthatmap is a project mainly written in OBJECTIVE-C and C++, it's free.
A sample iPhone SDK project demonstrating how to stop following a user's location on user touches.
This is a quick sample I put together to accompany my blog post titled "Making your iPhone app's maps work like Apple's". Please read that article for more information about the project and what it is for.
