• Happens within an animation block:

Starting Core Animation
- 2. What is Core Animation? • Framework for easily creating animated user interfaces. • Tightly integrated with UIKit. • Animate properties over time. • Layer based.
- 3. Where is Core Animation Used? • Everywhere! • Navigation controllers, displaying modal view controllers, deselecting cells in a table view, flipping to an info screen, etc!
- 4. UIView Animation’s • What you need most of the time. • Happens within an animation block: [UIView beginAnimations:nil context:NULL]; // change stuff [UIView commitAnimations];
- 5. Customizing, a little. • [UIView setAnimationDuration:] • [UIView setAnimationCurve:] • UIViewAnimationCurveEaseInOut UIViewAnimationCurveEaseIn UIViewAnimationCurveEaseOut UIViewAnimationCurveLinear • Delay, repeat count, etc.
- 6. Built-in Transitions • UIViewAnimationTransitionFlipFromLeft • UIViewAnimationFlipFromRight • UIViewAnimationTransitionCurlUp • UIViewAnimationTransitionCurlDown
- 7. Transforms • setTransform:(CGAffineTransform) • Rotation, scale, translation, etc
- 8. Demo
- 9. Layers • 2d object in 3d space. • “Animation Container” • Override layerClass method to change the type of a layer which your view uses.
- 10. Layer Types • CALayer • CAScrollLayer • CATiledLayer • CAEAGLLayer
- 11. Custom Animations • Link against QuartzCore framework. • Override actionForLayer:forKey: to return custom animation for property changes. • Set animation on a layer directly to trigger an immediate animation.
- 12. Animation Types • CABasicAnimation • Go from point A to point B. • CAKeyframeAnimation • Go from A to B to C, etc. • Animate along a path or by setting values and times • Set calculation mode to paced, linear, or discrete. • CAAnimationGroup • Group multiple animations together.
- 13. Demo!
