Yii框架允許開發者使用自己喜好的模板語法(例如Prado, Smarty)來編寫控制器或掛件的視圖. 這可以透過編寫和安裝一個viewRenderer應用元件來實現. 這個視圖渲染器攔截CBaseController::renderFile的調用，透過自訂的模板語法編譯視圖文件，然後渲染最終編譯結果.

Info: 只有當編寫的視圖很少復用時才推薦使用自訂模板語法. 否則的話，在應用中復用視圖將會強制使用同樣的模板語法.

接下來, 我們會介紹如何使用 CPradoViewRenderer,一個和Prado框架類似，允許開發者使用自定義模板語法的視圖渲染器. 如果你想要發展自己的視圖渲染器, CPradoViewRenderer是一個很好的指南.

1. 使用`CPradoViewRenderer`

To use CPradoViewRenderer, we just need to configure the

By default, CPradoViewRenderer will compile source view files and save the resulting PHP files under theruntime directory. Only when the source view files are changed, will the PHP filefiles be reen the source degradation.

Tip:

While CPradoViewRenderer mainly introduces some new template tags to make writing views easier and faster, you can still write PHPs olloas usual inwe views. that are supported by CPradoViewRenderer.

組件標籤 Component tags are used to insert a widget in a view. It uses the following syntax:

return array(

            'class'=>'CPradoViewRenderer',
        ),
    ),
);

Note:

The value for
showRefreshButton

is specified as

{false}

instead of

"false"

because the latter means a string instead of a boolean.
