onClick不会呈现其他React组件

Question

I've created a SocialShare component which I want to render when Share button is clicked on any of my other components.

import React, {Component} from 'react';
import {View, Share, Button} from 'react-native';

export class SocialShare extends Component {

  onShare = async () => {
    try {
      const result = await Share.share({
        message:
          'React Native | A framework for building native apps using React',
      });

      if (result.action === Share.sharedAction) {
        if (result.activityType) {
          // shared with activity type of result.activityType
        } else {
          // shared
        }
      } else if (result.action === Share.dismissedAction) {
        // dismissed
      }
    } catch (error) {
      alert(error.message);
    }
  };

  render() {
    return (

      this.onShare()

      );
  }
}

This is how I am calling this component from another component:

<View>
    <Button onClick={() => this.onShareButtonClick()}>Button</Button>
         {this.state.showShareComponent ?
             <SocialShare /> :
             null
         }
</View>

onShareButtonClick function:

onShareButtonClick(){        
        this.setState({
            showShareComponent: !this.state.showShareComponent,
        })
    }

On click of button, this is the error I am getting:

Invariant Violation: Objects are not valid as a React child (found: object with keys {_40, _65, _55, _72}). If you meant to render a collection of children, use an array instead.
    in SocialShare 

What's wrong with my code?

Edit: As per suggestions, modified my SocialShare class to this:

import React, {Component} from 'react';
import {View, Share, Button} from 'react-native';

export class SocialShare extends Component {
  constructor(props) {
    super(props);
    this.state = {
        asyncCompleted: false,
    };
  }
  onShare = async () => {
    try {
      const result = await Share.share({
        message:
          'React Native | A framework for building native apps using React',
      }).then(
        this.setState({asyncCompleted: true})
      );



      if (result.action === Share.sharedAction) {

        if (result.activityType) {
          // shared with activity type of result.activityType
        } else {
          // shared
        }
      } else if (result.action === Share.dismissedAction) {
        // dismissed
      }
    } catch (error) {
      alert(error.message);
    }
  };


  render() {
    return (

      <View>
      {this.state.asyncCompleted ? this.onShare() : null}
      </View>
      );
  }
}

Now, nothing happens on click of button from my other class.

Seems to me like the main issue is that your render method is attempting to render a promise directly, as would be returned by the asynchronous onShare() method. Instead, you should make the asynchronous code update the component's state, which can then trigger a render that will be based on this state value rather than the direct output of onShare()
