react-navigation之TabNavigator, StackNavigator使用配合redux

我在react-navigation的组件StackNavigator 和TabNavigator组合使用在加上redux，出现如下问题

there is no route defined for key ***must be one of 

这个类似的在 react-navigation的github也有，StackNavigator里嵌套一个TabNavigator， 

navreducer传递 AppNavigations就放入 <Provider>中 render 出来 显示了

const AppNavigations = ({ dispatch, nav }) => {
	return <Navigator navigation={addNavigationHelpers({ dispatch, state: nav })} />
}
  
const mapStateToProps = state => ({
  nav: state.navreducer,
});

module.exports = connect(mapStateToProps)(AppNavigations);

const allReducers = combineReducers({

	nav: navreducers,
});

那么navreducers的配置就是重点了， 不注意 就把TabNavigator里面的route 配置进去了

export const nav = (state, action) => {

    switch (action.type) {
         //TabNavigator 里模块
        case '****':
            return Navigator.router.getStateForAction(
                NavigationActions.navigate({ routeName: 'Tabchild' }),
                state
            );
        case '**':
        //TabNavigator 里模块
            return Navigator.router.getStateForAction(
                NavigationActions.navigate({ routeName: 'Tabchild' }),
                state
            );
        case 'WebDetail':
            return Navigator.router.getStateForAction(
                NavigationActions.navigate({ routeName: 'WebDetail' }), {...state, webViewURL: action.webViewURL }
            );
        default:
            return Navigator.router.getStateForAction(action, state) || state;

    }
}

export const navreducer = (state, action) => {
    switch (action.type) {
        case 'WebDetail':
            return Navigator.router.getStateForAction(
                NavigationActions.navigate({ routeName: 'WebDetail' }), 
                {...state, webViewURL: action.webViewURL }
            );
        default:
            return Navigator.router.getStateForAction(action, state) || state;
    }
}

<TouchableOpacity onPress={()=> {
						
			this.props.navigation.dispatch({ 
				type: 'WebDetail', webViewURL: data.alt 
							});
						}}>
</TouchableOpacity>

webview 需要的参数通过state就能获取到

class WebView extends Component {
	render() {
		return <WebView source={{uri: this.props.url}}/>
	}
}


function mapStateToProps(state) {
	return {
		url: state.navreducer.webViewURL
	}
}

	<TouchableOpacity onPress={()=> {
		this.props.navigation.navigate('WebDetail', webViewURL);
						}}>
				
	</TouchableOpacity>
