react-native hooks

react-native v0.59.0-rc.3增加React Hooks特性

react hooks 是一个已经在提议中的新功能,已在React16.7版本中发布

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

export default function Example() {
  const [count, setCount] = useState(0);
  return (
    <View style={styles.container}>
      <Text>You clicked {count} times</Text>
      <Button onPress={() => setCount(count + 1)} title="Click Me" />
    </View>
  );
}
