iPhone, is there any drawing sketch framework library can be use ?

Question

hi all,

I want build a sketch pad app on iPhone, I assume that this type app has already been developed long time , maybe some open source code can be use for this purpose ?

anyone can give tip on this field ?

Thanks ...

Answer 1

Take a look at the Sketch example for MacOS X Cocoa, then at UIBezierPath. Much of the drawing code should be easily portable with a regexp, although the UI and controller would need rewriting.
