React Native Hooks设置初始日期，然后设置更新日期

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

const MyComponent = () => {
  const [date, setDate] = useState(new Date());

  return (
    <View>
      <Text>{date.toDateString()}</Text>
    </View>
  );
};

export default MyComponent;

import React, { useState } from 'react';
import { View, Text, Button } from 'react-native';

const MyComponent = () => {
  const [date, setDate] = useState(new Date());

  const handleUpdateDate = () => {
    const tomorrow = new Date(date);
    tomorrow.setDate(date.getDate() + 1);
    setDate(tomorrow);
  };

  return (
    <View>
      <Text>{date.toDateString()}</Text>
      <Button title="Update Date" onPress={handleUpdateDate} />
    </View>
  );
};

export default MyComponent;
