In the above animation, the layer rotates from 45° to -45°, but this time it has two separate stages: first, it rotates from 45° to 22° during the first two-thirds of the animation duration, and then it rotates all the way to -45° in the time remaining. Take a look at the following simple layer keyframe animation example: You’ll also need to supply the time that the animation should reach each value’s key point. The elements of values are the measured milestones of your animation. Instead of fromValue and toValue, CAKeyframeAnimation uses an array of values to animate through, named values. Using fromValue and toValue, Core Animation progressively modifies a particular layer property between those values over a specified duration.įor instance, when you rotate a layer between 45° and -45° (or π/4 and -π/4 for you math types out there) you only need to specify those two values and the layer renders all intermediate values to complete the animation: Think for a moment how a basic animation works. In Chapter 17, “Stroke and Path Animations”, you’ll learn how to take layer animations even further and animate your layers along a given path.įor now, you’ll walk before you run and create a funky wobbly effect for your first layer keyframe animation. In this chapter, you’ll create a number of layer keyframe animations, from the very basic to more advanced animations that simulate real-world collisions. Even though that sounds restrictive at first, you can create some very compelling effects with CAKeyframeAnimation. You can define different key points of the animation, but you can’t have any gaps or overlaps in your animation. In contrast, CAKeyframeAnimation lets you animate a single property on a given layer. View keyframe animations are a simple way to combine independent simple animations together they can animate different views and properties, and the animations can overlap or have gaps in between. Keyframe animations on layers are a bit different than keyframe animations on a UIView. 18.4 Interactive replication animations.18.3 Animating CAReplicatorLayer properties.17.1 Creating interactive stroke animations.14.2 Creating a layer keyframe animation. ![]() Layer Keyframe Animations & Struct Properties
