Introduce：
1 this demo I according to the current market commonly used wheels and animation effect and write a kit
2 most of the wheels I do not package, but the principle of a simple written out for everyone to learn or use, why not package? Because it is too simple, did not meet their requirements.
3 inside most of the wheels I have used in their own projects, so we can rest assured that use, can be based on their own needs to package
中文介绍：
1.这个demo我根据目前市面上常用的轮子及动画效果而写出的一个kit
2.里面大部分轮子我都没有封装，而是简单的将原理写出来，供大家学习或者使用，为什么不封装？因为太简单了，没达到自己的要求。
3.这里面大部分的轮子我都用在自己的项目中，所以大家放心使用，可以根据自己的需求去封装
