就导导航栏的传值,可分为两种:
1.通过类似于iOS中的通知DeviceEventEmitter来实现组件之间的通讯,相关链接见:http://www.cnblogs.com/hd1992/p/5659261.html
2.导航栏需要向它的组件传值,一个navigator组件被StackNavigator(...)
创建出来,可以伴随以下属性。
·screenProps
- 为子界面传递额外的参数、选项,for example:
const SomeStack = StackNavigator({
// config 配置该navigator});<SomeStack
//通过this.props.screenProps获得该参数内容 screenProps={
/* this prop will get passed to the screen components as this.props.screenProps */}/>

3.用redux管理状态(暂时没去研究).
tabbarNavigation 如何隐藏tabbar:
据官网介绍:https://github.com/happypancake/react-native-tab-navigator
Hiding the Tab Bar
You can hide the tab bar by using styles. For example:
let tabBarHeight = 0;
<TabNavigator
tabBarStyle={{ height: tabBarHeight,overflow: 'hidden' }}
sceneStyle={{ paddingBottom: tabBarHeight }}
/>
