## ViewBuilder
> 通过`ViewBuilder`视图构建类，我们可以映射和扩展其他构建器，已内置的构建器有`table`、`form`
### 映射表格构建器
~~~
$tableBuilder = ViewBuilder::table();
~~~
### 映射表单构建器
~~~
$formBuilder = ViewBuilder::form();
~~~
### 自定义构建器
+ 在`buider`目录下创建构建器目录：如`panel`
+ 在`panel`目录下创建构建类，如：`Builder.php`
~~~
namespace app\builder\panel;
use yii\base\BaseObject;
use app\builder\contract\BuilderInterface;
class Builder extends BaseObject implements BuilderInterface
{
/**
* 渲染组件
* @param Controller $context
* @return string
* @author cleverstone
* @since 1.0
*/
public function render(Controller $context)
{
}
}
~~~
> 注意：`Builder.php`必须继承`BaseObject`且继承`BuilderInterface`结构
+ 在`ViewBuilder`中注册`panel`构建器
~~~
namespace app\builder;
use yii\base\Component;
use yii\base\NotSupportedException;
/**
* 视图构建器
*
* @method \app\builder\panel\Builder panel(array $config = []) static panel构建器方法
* @author cleverstone
* @since 1.0
*/
class ViewBuilder extends Component
{
/**
* yii-manager version
*
* @var string
*/
public $version = '1.0.0';
/**
* 注册构建器
*
* @var array
* @since 1.0
*/
public static $builderMap = [
'panel' => \app\builder\panel\Builder::class, // panel
];
}
~~~
+ 其他实现建议参考内置`table`构建器
