将状态变量重置为初始值xcode

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

const App = () => {
  const [count, setCount] = useState(0);
  const initialCount = 0;

  const resetCount = () => {
    setCount(initialCount);
  };

  return (
    <View>
      <Text>Count: {count}</Text>
      <Button title="Increment" onPress={() => setCount(count + 1)} />
      <Button title="Reset" onPress={resetCount} />
    </View>
  );
};

export default App;

import SwiftUI

struct ContentView: View {
    @State private var count = 0

    var body: some View {
        VStack {
            Text("Count: \(count)")
            Button(action: {
                count += 1
            }) {
