swift 出来后有很多优秀的第三方绘图、动画框架,最近项目需要使用了 Charts
Github: https://github.com/danielgindi/Charts
因为是在Object-c工程上使用,所以使用cocoapod 工具导入,省了很多麻烦
podfile:
target ‘DianLeIE’
pod ‘Charts‘, ‘~> 3.0.0‘
pod ‘Realm‘, ‘~> 2.0.2‘
use_frameworks!
在开始使用的时候遇到了一些问题,因为之前用core plote 第三绘图,很多都需要自己自定义,但是在Charts 上预留了很多自定义的方法,在使用时就不需要过多的计算,可能就是因为这个原因所以在github上star 很高,并且这个还有安卓版,坑的地方就是是看安卓使用文档,不过还是很容易看懂的,字面意思差不多。
