React native #react native[0.42]-使用Redux进行新导航-无法将状态映射到道具

注册护士：0.42

我尝试使用新的导航（已发布）+redux，但我无法在商店经过的屏幕中将redux的初始状态映射到道具

我接着说：

我已经写了我的自定义减速机

导出常量类型={
...
}
导出常量actionCreators={
身份验证：（）=>async（dispatch，getState）=>{
...
}
}
常量初始状态={
认证：{
...
}
}
导出常量缩减器=（状态=初始状态，操作）=>{
常量{auth}=state
const{type，payload，error}=action
开关（类型）{
...
}
返回状态
}

我在你的index.ios.js中找到了你做错的地方，从'appReducer'更改

导入*从'appReducer'导入{reducer}那么您当前的组合减速器功能如下

const appReducer = combineReducers({
  nav: navReducer,
  app: reducer
});

然后在home.js中，您的mapStateToProps应该是

const mapStateToProps = (state) => ({
  //This is the problem: Here 'state' has no 'auth' object attached to it
  authState: state.app    //remember store only contains reducers as state that you had passed in combineReducer function
})

现在在组件中使用它，如

this.props.authState.auth        //remember you had wrapped your auth object within initialState object
