How to make pencil stroke for iPhone app?

Question

I would like to make a pencil stroke in an iPhone application, which can draw lines such as you can see in this picture:

Can anybody show me how I could implement these types of stroke?

Answer 1

There are no built-in functions for drawing this kind of stroke. You will have to come up with your own texture image and draw it repeatedly along the path. There are no built-in functions for getting points along a path either.
