React-Redux mapDispatchToProps不接收mapStateToProps

在我的mapStateToProps函数中,我将idToken和accessToken设置为存储在状态的值.这样做可以从组件中引用这些值.在mapDispatchToProps中,我尝试在我的操作中使用这些道具作为参数.但是,ownProps是一个空对象.为什么没有idToken和accessToken？

容器：

import { connect } from 'react-redux'
import { toggleAddQuestionModal,fetchFriends } from '../actions'
import AddQuestionButtonComponent from '../components/AddQuestionButton'

const mapStateToProps = (state) => {
  auth = state.auth
  return {
    idToken: auth.token.idToken,accessToken: auth.profile.identities[0].accessToken,}
}

const mapDispatchToProps = (dispatch,ownProps) => {
  return {
    didPress: (idToken,accessToken) => {
      dispatch(toggleAddQuestionModal(true))
      dispatch(fetchFriends(ownProps.idToken,ownProps.accessToken))
    }
  }
}

AddQuestionButton = connect(
  mapStateToProps,mapDispatchToProps
)(AddQuestionButtonComponent)

export default AddQuestionButton

零件：

'use strict';

import React,{
  Text,View,TouchableHighlight,PropTypes,} from 'react-native'

import styles from './styles'

const AddQuestionButton = ({ didPress,idToken,accessToken }) => (
  <TouchableHighlight style={styles.actionButton} onPress={didPress(idToken,accessToken)}>
    <Text style={styles.actionButtonText}>+</Text>
  </TouchableHighlight>
)
AddQuestionButton.propTypes = {
  idToken: PropTypes.string.isRequired,accessToken: PropTypes.string.isRequired,didPress: PropTypes.func.isRequired,}

export default AddQuestionButton

为什么我不能从ownProps访问idToken和accessToken？如果这样做不正确,应该如何访问idToken和accessToken？

谢谢！

function mapStateToProps(state,ownProps) {
  return {
    isFollowing: state.postsFollowing[ownProps.id]
  };
}

function mergeProps(stateProps,ownProps) {
  const { isFollowing } = stateProps;
  const { dispatch } = dispatchProps;
  const { id } = ownProps;

  const toggle = isFollowing ?
    unfollowPostActionCreator :
    followPostActionCreator;

  return {
    ...ownProps,toggleFollow: () => dispatch(toggle(id)))
  };
}

ToggleFollowButton = connect({
  mapStateToProps,null,// passing null instead of mapDispatchToProps will return an object with the dispatch method
  mergeProps
})(ToggleFollowButton)
