Smooth Paint Brush

I am developing an iPad Application which allows the users to select the Air Brush , this is being achieved by drawing the image texture in the current context.

But when i draw the image i am getting this king of effect - enter image description here

where as to avoid this i tried using blendmodeLighten , which give me the right way as below enter image description here

but using this i came across the another problem, where when i draw another color on the top of one color , due to blending i am not the getting the actual color.

Can any one help me on this ?

I'm not sure if this is what you want.

You can create another bitmap context using CGBitmapContextCreate, and draws the strokes on that context.

And using blend mode kCGBlendModeColor, you can combine with current context and bitmap context.

Hope it helps.
