Swift 中的矢量动画框架

# ShapeAnimation-Swift Vector animation framework in Swift based on [SwiftGraphics](https://github.com/schwa/SwiftGraphics) for iOS 8. With ShapeAnimation you can easily create various animations with a nice Swift based syntax. [![Travis][travis_img]][travis] [travis]: https://travis-ci.org/rhcad/ShapeAnimation-Swift [travis_img]: https://travis-ci.org/rhcad/ShapeAnimation-Swift.svg?branch=master The current development happens on the [develop][develop] branch. Code is merged back on master branch infrequently. SVG animation development with [SVGKit](https://github.com/SVGKit/SVGKit) happens on the [SVG][svg_branch] branch. [develop]: https://github.com/rhcad/ShapeAnimation-Swift/tree/develop [svg_branch]: https://github.com/rhcad/ShapeAnimation-Swift/tree/SVG ## What's included * ShapeView class which contains vector shape layers. * Helper functions to add image, text, circle, regular polygon, lines and other shapes. * Support gradient fill with animation. * Enumerate, hit-test or find layers. * Animation extension functions of CALayer. * opacityAnimation, flashAnimation, backColorAnimation * scaleAnimation, tapAnimation, transformAnimation * rotate360Degrees, rotationAnimation * shakeAnimation, moveAnimation, moveOnPathAnimation * slideToRight, slideAnimation, flipHorizontally, flipVertically * Layer dragging: constrainCenterToSuperview, bringOnScreen * Animation extension functions of CAShapeLayer. * strokeStartAnimation, strokeEndAnimation, lineWidthAnimation * strokeColorAnimation, fillColorAnimation, dashPhaseAnimation * switchPathAnimation * Group animation and cascaded animation. * animationGroup for the same layer * applyAnimations for multiple layers * Use the block-based function in apply() to play cascaded animations. * Pause, resume or stop animations. * Animations with customized properties * Use AnimationLayer class to draw customized animations. * Animation with sliders example: [EllipseViewController.swift](ShapeAnimation_UITest/EllipseViewController.swift)        ## Usage Please see the examples in [MasterViewController.swift](ShapeAnimation_UITest/MasterViewController.swift). ``` Swift let layer1 = self.addLinesLayer(view, points:[(10.0,20.0),(150.0,40.0),(120.0,320.0)]) layer1.strokeEndAnimation().apply() { layer1.shakeAnimation().apply() } let la2 = self.addLinesLayer(view, points:points2, color: UIColor.blueColor()) lla2.scaleAnimation(from:1, to:1.1, repeatCount:3).apply(duration:0.3) let la3 = self.addLinesLayer(view, points:points3, color: UIColor.greenColor()) la3.flashAnimation(repeatCount:6).apply() let la4 = self.addLinesLayer(view, points:[(10.0,20.0), (150.0,40.0), (120.0,120.0)]) let a1 = la4.moveOnPathAnimation(path).setDuration(1.6) let a2 = la4.rotate360Degrees().setRepeatCount(2) animationGroup([a1, a2]).autoreverses().apply() ``` ## Help Wanted All of this code is very much a _*work in progress*_. I'm adding and changing functionality as needed. Your help wanted. Please fork this project and submit pull requests or [issues][issues].
