let options = {
frequency: 3000,
enableHighAccuracy: true
};
this.watch = Geolocation.watchPosition(options);
this.watch.subscribe((data) => {
alert("latitude: "+data.coords.latitude);
alert("longitude: "+data.coords.longitude);
console.log("latitude: "+data.coords.latitude);
console.log("longitude: "+data.coords.longitude);
this.notifyLocation(data.coords);
});
let backgroundOptions = {
desiredAccuracy: 10,
stationaryRadius: 10,
distanceFilter: 30
};
this.backGeolocation.configure((location) => {
this.notifyLocation(location);
}, (err) => {
console.log(err);
}, backgroundOptions);
this.backGeolocation.start();
return this.position;
}示例2: startWatch
startWatch() {
this.subscription = Geolocation.watchPosition(this.options).subscribe(position => {
this.record=true;
console.log(position);
this.geo = position;
});
}示例3: watchPosition
/**
