你好，谢谢你的教程，让我学到了许多东西。
我是看你的博客 http://blog.csdn.net/yuanguozhengjust/article/details/50601111 学习的。
在这篇博文里，控件是

render() {  
    return (  
        <TouchableWithoutFeedback>  
            <View style={{alignItems:'center',flex:1}}>  
                <Image style={styles.iconImg} />  
                <Text>Example Text</Text>  
            </View>  
        </TouchableWithoutFeedback>  
    );  
}

请问为什么要在View外面套个 TouchableWithoutFeedback ？ 我看这个 TouchableWithoutFeedback好像也没用到？

http://m.jd.com/index/recommend.action?_format_=json&page=1 这个网址的解析无法工作

图片的点击事件写在_renderPage方法中，会自动的点击，该怎么处理？

底部图标无法上下居中，按照楼主？（不知道叫什么好，233）图标能居中是通过 marginTop: 12.5 将图标挤下来，但是在我这里不起作用

是tab-navigator的版本不一样造成的吗？刚学习RN 太懂，有什么方法可以让图标居中的
下面代码

这个开源库ios和android都通用么，现在有bug么？
