An example project using CAKeyframeAnimations and Quartz in a MacOS app. The only thing it does is open up and flash colors on the screen.
This app was built with the following technologies:
- AutoLayout for centering the label
- Quartz/Core Graphics for manipulating layers
- Core Animation for cycling the colors and tweening between colors
If you are prone to epilepsy, do not open this app. It produces flashing colors that may or may not trigger epilepsy. Better stay on the safe side.
