XMCircleGestureRecognizer

=========================

**XMCircleGestureRecognizer** was written by **[Michael Teeuw](https://twitter.com/michmich)**

## What is it?

An one finger circle gesture recognizer written in swift.

## How to use

Add a XMCircleGestureRecognizer recognizer to your view

    let cgr = XMCircleGestureRecognizer(midPoint: self.view.center, innerRadius:10, outerRadius:200, target: self, action: "rotateGesture:"))

    view.addGestureRecognizer(cgr)

    

Or, of you don't need a minimum and maximum distance to your center point:

    let cgr = XMCircleGestureRecognizer(midPoint: self.view.center, target: self, action: "rotateGesture:"))

    view.addGestureRecognizer(cgr)

    

Add a gesture responder function to your target to respond to the gesture:

    func rotateGesture(recognizer:XMCircleGestureRecognizer)

    {

        if let rotation = recognizer.rotation {

            // rotation is the relative rotation for the current gesture in radians

        }

        

        if let angle = recognizer.angle {

            // angle is the absolute angle for the current gesture in radians

        }

        

        if let distance = recognizer.distance {

            // distance is the absolute distance from the midPoint

        }

    }

    

If you like to transform the values from radians to degrees, simply add ```.degrees``` to the variable:

    if let rotation = recognizer.rotation {

        // rotation.degrees is the relative rotation for the current gesture in degrees

    }

This is my fist open source Swift class. So be gentle. ;)
