BezierAndGraphic

Brief Intro

An iOS project (Swift) to pratice the UIBezier path and CAAnimation on the CALayer.

Key Features:

  • CAShape Layer
    • generate CAShapelayer
    • Add UIBezier path's CGPath to CAShape Layer
    • Draw round corner rect on CAShape Layer
    • Draw Circle with radius on CAShape Layer
  • UIBezier Path
    • Draw Quard Curve Line
    • Add CAAnimation to CALayer
    • Key-Value Pair for the UIBezier path animation

Comments:

  • Relationship between UIView and CALayer
    • UIView和CALayer的frame、bounces始终保持一致
    • CALayer是图层，和界面展示相关。UIView很多属性和方法和CALayer里的属性和方法是一致的。UIView可以看做是CALayer的管理者，除了负责视图展示之外，还可以处理一些事件，比如手势交互等。但我们对UIView做的一些有关视图显示和动画的操作，本质上还是对CALayer进行的操作.
