 1 | # iCards
 2 | A container of views (like cards) can be dragged!<br>
 3 | ---
 4 | 视图容器，视图以卡片形式层叠放置，可滑动。<br>
 5 | ---
 6 | There are only visible cards in memory, after you drag and removed the top one, it will be reused as the last one.<br>
 7 | 内存中只会生成可见的卡片，顶部的卡片被划走之后，会作为最后一张卡片循环利用。<br>
 8 | 
 9 | You can find a Swift version here:<br>
10 | 你可以在这里找到Swift版：[SwipeableCards](https://github.com/DingHub/SwipeableCards)<br>
11 | 
12 | 这里有一篇：[《探索之旅：代理原理》](http://www.swifthumb.com/thread-14968-1-1.html)，可作为iCards的详细说明文档。
