CAAnimation-EasingEquations

A category on CAAnimation that provides a number of easing equations to add some zazz to your app (with examples!)

To use

• Link your build target with QuartzCore
  • Select your project in Xcode's project navigator
  • Select your project's target
  • Navigate to "Build Phases"
  • In the "Link Binary with Libraries" section, click the '+' button
  • Select QuartzCore and click "Add"
• Add CAAnimation+EasingEquations.h and CAAnimation+EasingEquations.m to your project
• Enjoy!

Because this uses CoreAnimation, animations are applied to CALayer objects. For example, if we wanted a UIView to become completely transparent over the course of a second, the code to do that would look like this:

    [CAAnimation addAnimationToLayer:animatedView.layer
                         withKeyPath:@"opacity"
                            duration:1
                                  to:0
                      easingFunction:CAAnimationEasingFuctionEaseInBounce];

In this example, the bounce ease-in function would be used.
