I'm doing iPhone programming and I need to learn about Core Graphics.

It looks Apple doesn't provide a programming guide for Core Graphics and I'm having hard times following the code that uses Core Graphics.

Do you suggest any reference or book for learning Core Graphics?

I would start here iOS Reference Library and type in Core Graphics. Also, check out 'Sample Code' and 'Graphics & Animation'. You will find that Core Animation tends to subsume Core Graphics, so reading about Core Animation might be helpful.

I made a github repo with several examples of how to use some CoreGraphics features, it may be a starting point: RPCGSandbox.
