hi every one, am making a drawing application for iphone, am facing a prob when i use the core graphics, i am using the CGContext for drawing, and my code is in touchesMoved method, my problem is, if i use the same way in openGL it seems gud, and am getting smooth drawing but, this core graphics guy, also have the same code, but he works pretty bad, in the simulator core graphics drawing is gud, but when i install the app to my device it doesn't have smooth drawing...
instead it maps line between very few points on my UITouch. i don no how to rectify this...
