UIDynamics-Helpers

This repository is filled with helping code for UIDynamics stuff. All of the UIDynamics Helpers are housed in the top level "MFLDynamicsHelpers" folder, and their are use examples throughout.

###MFLAlphaCollision - Image To Boundary - Alpha Only Collisions

This class will help you create a boundary behavior for any arbitrary image. It will trace any non zero alpha pixels in an image, and then construct a UIBezierPath from the result to use as a boundary.

     [MFLAlphaCollision addBoundaryToBehavior:self.collisionBehavior
                                withImageView:self.boundaryImageView
                                forIdentifier:@"someIdentifier"];

OR

     [MFLAlphaCollision addBoundaryToBehavior:self.collisionBehavior
                                     withView:self.complicatedView
                                forIdentifier:@"someIdentifier"];

###MFLBoundaryPreview - Trace Boundaries

This class will allow you to trace all on screen boundaries simply and easily to make it much easier to test your path drawing.

To begin tracing all of your boundaries, change the class of your UIView to MFLBoundaryPreview and set your view's MFLBoundaryPreviewDelegate to your UIViewController, ensuring it has a property named collisionBehavior.
