如何使用react原生导航在iOS上增加向后滑动区域？

npm install react-navigation

import React from 'react';
import { View, TouchableOpacity, Text } from 'react-native';
import { createStackNavigator } from 'react-navigation';

const CustomNavigation = createStackNavigator({
  Home: {
    screen: HomeScreen,
    navigationOptions: ({ navigation }) => ({
      headerTitle: 'Home',
      headerLeft: (
        <TouchableOpacity onPress={() => navigation.goBack()}>
          <Text>Back</Text>
        </TouchableOpacity>
      ),
    }),
  },
});

import React from 'react';
import { View } from 'react-native';
import CustomNavigation from './CustomNavigation';

export default function App() {
  return (
    <View style={{ flex: 1 }}>
      <CustomNavigation />
    </View>
  );
}
