Increase frequency calls of touchesMoved

问题:

Is there a way to increase the frequency calls of touchesMoved than the default? I need more calls of it to draw a smooth circle. It gets called not too frequent by default and so I get an edgy circle. Is there a way to tweek the frequency of touchesMoved calls?

Thanks

I think this is what you are looking for:

UIBezierPath

It comes with code examples, etc.
