探索 React Native 地理定位神器：react-native-location

import React, { useEffect, useState } from 'react';
import { Text, View } from 'react-native';
import RNLocation, { GeojsonPoint } from 'react-native-location';
 
const App = () => {
  const [location, setLocation] = useState<GeojsonPoint | null>(null);
 
  useEffect(() => {
    RNLocation.getCurrentPosition({
      timeout: 10000, // 10 seconds
      maximumAge: 1000, // 1 second
      enableHighAccuracy: true, // true = better accuracy, but slower on devices
    }).then(location => {
      setLocation(location);
    }).catch(error => {
      console.error(error);
    });
  }, []);
 
  return (
    <View>
      {location ? (
        <View>
          <Text>Latitude: {location.latitude}</Text>
          <Text>Longitude: {location.longitude}</Text>
        </View>
      ) : (
        <Text>Fetching location...</Text>
      )}
    </View>
  );
};
 
export default App;

这段代码使用React Native和react-native-location库来获取当前的地理位置。它首先尝试获取位置，然后将其显示在屏幕上。如果获取位置失败，它会在控制台中报错。这个例子展示了如何在React Native应用中使用地理定位功能。
