xcode CABasicAnimation 键

Question

提问by Mosab Alawad

I'm trying to know what are all the possible keys used in CABasicAnimation

我想知道所有可能使用的键是什么 CABasicAnimation

like this one:

像这个：

CABasicAnimation *imageRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];

which makes a rotation ... where can I find all possible keys? and thanks in forward

这使得旋转......我在哪里可以找到所有可能的键？并感谢转发

You may simplywrite: CABasicAnimation(keyPath: #keyPath(CAShapeLayer.strokeColor))

你可以简单地写： CABasicAnimation(keyPath: #keyPath(CAShapeLayer.strokeColor))

Also, use command+shift+o, open, for example, CALayer.h and watch a comments. **Apple team provides information about animatable feature

另外，使用 command+shift+o，打开，例如 CALayer.h 并观看评论。**Apple 团队提供有关动画功能的信息

You can find them in "Key Path Support for Structure Fields"section of CoreAnimation programming guide

您可以在CoreAnimation 编程指南的“结构字段的关键路径支持”部分找到它们

Answer 6

回答by IluTov

You can basically use every possible keyPath. So if an object implements the property 'alpha', like all views do, you can let this property animate automatically.

您基本上可以使用所有可能的keyPath。所以如果一个对象实现了属性“alpha”，就像所有视图一样，你可以让这个属性自动动画。

The CAAnimation then calculates steps between the start point, and the end point of the animation, sets them and redraws the view.

CAAnimation 然后计算动画的起点和终点之间的步骤，设置它们并重绘视图。
