#### 自定义校验
我们提供了 `validateStatus` `help` `hasFeedback` 等属性，你可以不需要使用 `Form.create` 和 `getFieldDecorator`，自己定义校验的时机和内容。
1. `validateStatus`: 校验状态，可选 'success', 'warning', 'error', 'validating'。
2. `hasFeedback`：用于给输入框添加反馈图标。
3. `help`：设置校验文案。

#### Customized Validation
We provide properties like `validateStatus` `help` `hasFeedback` to customize your own validate status and message, without using `Form.create` and `getFieldDecorator`.
1. `validateStatus`: validate status of form components which could be 'success', 'warning', 'error', 'validating'.
2. `hasFeedback`: display feed icon of input control
3. `help`: display validate message.
