如何在react原生中创建具有多个列和标题的iOS UIPicker？

npm install react-native-picker-select --save

import React, { useState } from 'react';
import { View, Text } from 'react-native';
import RNPickerSelect from 'react-native-picker-select';

const pickerData = [
  {
    title: '列1',
    data: [
      { label: '选项1', value: 'option1' },
      { label: '选项2', value: 'option2' },
      { label: '选项3', value: 'option3' },
    ],
  },
  {
    title: '列2',
    data: [
      { label: '选项A', value: 'optionA' },
      { label: '选项B', value: 'optionB' },
      { label: '选项C', value: 'optionC' },
    ],
  },
];

const [selectedValue, setSelectedValue] = useState(null);

<View>
  <Text>选择器标题</Text>
  <RNPickerSelect
    placeholder={{ label: '请选择', value: null }}
    items={pickerData}
    onValueChange={(value) => setSelectedValue(value)}
    style={{
      inputIOS: {
        fontSize: 16,
        paddingVertical: 12,
        paddingHorizontal: 10,
        borderWidth: 1,
        borderColor: 'gray',
        borderRadius: 4,
        color: 'black',
        paddingRight: 30,
        backgroundColor: 'white',
      },
    }}
  />
</View>
