Create Circular Path for an iPhone Application -

-

how can create circular path in iphone application on can detect finger touches?

you use $1 gesture recognizer. there open source gesture recognizer iphone here created adam preble.

you use 1 aspect of recognizer predefine shapes. once shapes defined , stored application, can use recognizer test if touch strokes match of defined shapes.

i use code adapted adam's recognize 6 different gestures in application (circle, s, squiggle...), , happy results.

it might lot of work 1 shape, although benefits of using $1 gesture recognizer recognize size circle drawn clockwise or counter-clockwise.
