我正在使用navigator.geolocation.watchPosition和getCurrentPosition实现健身跟踪器.它在Android和ios仿真器上工作正常,准确度为5/10m,但在iphone 5s上,我的准确度很差(50/65).

我发现当我在ios上同时运行现有的健身追踪器(strava)时,突然我的应用程序正在非常精确地检索GPS坐标.

很明显我必须缺少一些配置,因为默认情况下我的应用程序在iOS上使用不高.知道如何解决这个问题吗？

码:

const GPS_TIMEOUT_GET = 5000;
    const GPS_MAX_AGE = 1000;

    const GPS_DISTANCE_FILTER = 5;
    const GPS_TIMEOUT_WATCH = 60000;
    const GPS_MIN_ACCURACY = 50;

    //start the GPS into full time watching. Drains battery but brings best accuracy (required for our needs)
    let watchId = navigator.geolocation.watchPosition((position) => {
        }
        , (error) => {
            console.log(error);
        }
        , {
            enableHighAccuracy: true,
            timeout: GPS_TIMEOUT_WATCH,
            maximumAge: GPS_MAX_AGE,
            distanceFilter: GPS_DISTANCE_FILTER
        });

    //check GPS every X milliseconds)
    let intervalId = BackgroundTimer.setInterval(() => {
        navigator.geolocation.getCurrentPosition((geoPosition) => { …
