阿波罗 resetStore 不起作用

Question

请帮忙； 我有一个错误“undefined is not an object (evaluating 'this.props.client')

class FeedProfileBottom extends Component {

_onLogoutPress = function() {
  this.props.client.resetStore();
  return this.props.logout();
}

render() {
  return (
    <Root>
      <LogOutButton onPress={this._onLogoutPress}>
        <LogOutText>
          Logout
        </LogOutText>
      </LogOutButton>
    </Root>
  );
 }
}

export default withApollo(connect(undefined, { logout })(FeedProfileBottom));

您可能需要将组件的作用域显式绑定到函数。

class FeedProfileBottom extends Component {
  constructor (props) {
    super(props);
    this._onLogoutPress = this._onLogoutPress.bind(this);
  }
  // ...
