有没有办法让按钮在React Native中渲染我的相机组件？

npm install react-native-camera

yarn add react-native-camera

import React, { Component } from 'react';
import { View, TouchableOpacity, Text } from 'react-native';
import { RNCamera } from 'react-native-camera';

class CameraScreen extends Component {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <RNCamera
          style={{ flex: 1 }}
          ref={ref => {
            this.camera = ref;
          }}
        />
        <TouchableOpacity
          onPress={() => this.takePicture()}
          style={{ alignSelf: 'center', margin: 20 }}
        >
          <Text style={{ fontSize: 20, color: 'white' }}>拍照</Text>
        </TouchableOpacity>
      </View>
    );
  }

  takePicture = async () => {
    if (this.camera) {
      const options = { quality: 0.5, base64: true };
      const data = await this.camera.takePictureAsync(options);
      console.log(data.uri);
    }
  };
}

export default CameraScreen;
