【问题描述】:
我正在使用 react-native-maps 并使用 react-native api 进行地理定位。当我通过 api 使用位置时,模拟器上的返回显示我在旧金山而不是我所在的科罗拉多州丹佛市。我的位置无法显示我所在的位置是否有原因?
我的运行位置的函数
// 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", 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);
},
(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
},
有人遇到这个问题并知道如何解决吗?是 react-native 正在运行的网络还是不应该从我的笔记本电脑网络位置提取?
我已查看是否有其他人遇到此问题: Geolocation in React Native iOS 如果您搜索地理位置错误的 react-native ios,则堆栈上的搜索仅显示 6 个结果...google 也没有太大帮助。
感谢您的帮助
