weex wxc-navpage 导航栏标签在android、iOS下的使用问题。

Question

wxc-navpage： 标签在实际中是否有使用的规范：

以下是在实践中使用中用了两种不同的写法导致了android、iOS不同的呈现效果，不知道有没遇到过相同问题的人?

第一种写法

<template>
<wxc-navpage title="首页">
<div>
   <text>内容</text>
</div>
</wxc-navpage>
</template> 

• android：weex debug 呈现效果如下：
  

  导航栏下出现了一段空白

• android：真机运行 呈现效果如下:
  

  导航栏下的内容显示空白像是没有成功渲染。
  

• iOS：模拟器呈现效果 正常。
  

• iOS：weex debug 呈现效果
  

第二种写法

<template>
<wxc-navpage title="首页"></wxc-navpage>
<div>
   <text>内容</text>
</div>

• android：weex debug 呈现效果 正常
  

• android：真机呈现效果 正常
  

• iOS：模拟器呈现效果
  

  导航栏和内容全部空白。
  

• iOS：weex debug 呈现效果 正常
  

希望遇到类似问题的大神帮助指导下，谢谢了。

最终的代码：

<template>
<div>
    <wxc-navpage title="首页" background-color="#3683FF"  onclick="onClickTitle" title-color="#FF0000" left-item-title="搜索" left-item-color="#EA80FF" right-item-title="跳转" right-item-color="#EA80FF"></wxc-navpage>

Answer 1

问题已经解决，由于更新weex 时并没有重新对project 安装新的依赖 npm install
由于依赖存在差异，导致weex compile 编辑成js文件时， 针对Wex-nvrpage 标签下内容处理例子不一样。结论是对mac window 下各自生成的js 文件对比得出。

Answer 2

问下我从native的weex里push到新的weex，上面的导航条设置wxc-navpage没效果，显示的是系统的导航栏 也隐藏不掉 这个您是怎么处理的？

Answer 3

有demo没？大神
