原始測試XML如下:

<View flexDirection="row" width="300" height="auto"
    maxHeight="1000"
    left="20"
    top="50"
    justify="spaceAround"
    alignItems="stretch"
    paddingTop="10"
    paddingBottom="20"
    paddingLeft="15"
    paddingRight="15"
    backgroundColor="#FFCDB2">
    <View flex="2" height="auto" justify="center" alignItems="center" backgroundColor="#B5838D">
        <View width="{{ 50 / 2 + 10 }}"
            height="{{ 59 + 2.5 *2 -3 }}"
            backgroundColor="#6D6875"
            borderColor="#e63946"
            borderWidth="2"
            shadowColor="#d00000"
            shadowRadius="15"
            shadowOpacity="0.5"

        <Label text="測試標題2測試標題2測試標題2"
            fontSize="20"
            color="#ef233c"
            marginTop="10"
            lineNumber="3"
            backgroundColor="#00ff00">class="hljs-name"Label>

通過模板編輯器(目前只實現(xiàn)了功能,沒有實際意義上的編輯器工具)將表達式部分編譯成IR,代碼如下:

<View flexDirection="row" width="300" height="auto" maxHeight="1000" left="20" top="50" justify="spaceAround" alignItems="stretch" paddingTop="10" paddingBottom="20" paddingLeft="15" paddingRight="15" backgroundColor="#FFCDB2">

生成如上代碼,就可以交給引擎去渲染了,下面是項目整體的架構(gòu)設(shè)計:

目前Demo(iOS端)部分的調(diào)研效果已經(jīng)有了,帖一下上面IR XML渲染效果，如下:
