Draw symbols to cast spells in a game

[RomanRobot]

I am working on a Cocos2D game. What I want is for the user to draw a symbol that will execute a spell/action according to the predetermined symbol it most resembles. Cocos2D's OpenGL View is sitting inside of a view controller so I can still do UIKit stuff over it if necessary. So can you point me to a guide or something to simply implement what I'm looking to do?

you should be able to use UIGestureRecognizer to create a custom gesture
Documentation: Event Handling Guide for iOS: Creating Custom Gesture Recognizers
An Example for implementing it: Custom Checkmark Gesture Recognizer - Conceited Code
and you can use it in cocos2d: Adding UIGestureRecognizer support in cocos2d cocos2d for iPhone
in particular look this fork that show how to do it: https://github.com/xemus/cocos2d-iphone
