 If you want to get `ref` after `Form.create`, you can use `wrappedComponentRef` provided by `rc-form`, [details can be viewed here](https://github.com/react-component/form#note-use-wrappedcomponentref-instead-of-withref-after-rc-form140).

 经过 `Form.create` 之后如果要拿到 `ref`，可以使用 `rc-form` 提供的 `wrappedComponentRef`，[详细内容可以查看这里](https://github.com/react-component/form#note-use-wrappedcomponentref-instead-of-withref-after-rc-form140)。
