Reproduction link

http://jc.epanel.cn/project/501459/check/Plan

Steps to reproduce

登录，进入链接页面，点击检查单位下，编辑，出现树结构加载页面

What is expected?

1.this.treeNodesStates这个方法怎么使用
2.antd升级后子节点都选中，父节点没自动选中，希望子节点都选中，相应父节点自动选中

What is actually happening?

1.antd升级后子节点都选中，父节点没自动选中
2.说明this.treeNodesStates怎么使用

Environment Info
antd 3.26.0
React 15
System win10
Browser 谷歌

在 3.4.0 之前：树节点可以有很多，但在设置checkable时，将会花费更多的计算时间，因此我们缓存了一些计算结果（this.treeNodesStates）来复用，避免多次重复计算，以此提高性能,如何使用
