使用React Native和iOS模拟器进行错误的地理定位

我运行该位置的功能

// Get current users locaiton on load
  componentDidMount() {
    navigator.geolocation.getCurrentPosition((position) => {
      console.log(position);
      let newLat = parseFloat(position.coords.latitude);
      console.log("newLat",newLat);
      let newLng = parseFloat(position.coords.longitude);
      console.log("newLng",newLng);
      // set region of user to lat and long position
      // deltas set distance from marker (zoom) on map
      this.setState({
        region: {
          latitude: newLat,longitude: newLng,latitudeDelta: 0.0250,longitudeDelta: 0.0125
        },error: null
      });
      console.log(this.state);
    },// if error set state with error
      (err) => {
        console.log(err),// set location accuracy on
        // max time to find location in 5 sec
        // max time to use cached location for phone 5 sec
        { timeout: 5000,maximumAge: 5000 };
      }
    );

    // watch for changes and update location
    this.watchId = navigator.geolocation.watchPosition((position) => {
      console.log(position);
      let newLat = parseFloat(position.coords.latitude);
      console.log("newLat",(err) => {
        console.log(err),// set location accuracy on
        // max time to find location in 5 sec
        // max time to use cached location for phone 5 sec
        // distance before location called again 10 m
        { timeout: 5000,maximumAge: 5000,distanceFilter: 10 }
      }
    );
  }

我在初始状态下预设的位置是：

this.state ={
      region: {
          latitude: 39.739236,longitude: -104.990251,latitudeDelta: 0.1000,longitudeDelta: 0.0500
      },

这比iOS模拟器给我看的更近

任何人遇到这个问题,知道如何解决它？它是反应原生网正在运行的网络还是不应该从我的笔记本电脑网络位置拉？

我看过是否有其他人遇到过这个问题：
Geolocation in React Native iOS
如果你搜索geolocation错误的反应原生ios,那么堆栈上的搜索只会显示6个结果… google也没什么帮助.

谢谢你的帮助
