Geolocation

Enkel användning

package.json till att inkludera beroenden i ditt package.json :

{
    ...
    "dependencies": {
        ...
        "ionic-native": "^1.3.10",
        ...
    },
    ...
}

Så här använder du geolocation:

// custom-component.ts

import {Geolocation} from 'ionic-native';
import template from './custom-component.html';

@Component({
    selector: 'custom-component',
    template: template
})
export class CustomComponent {

    constructor() {

        // get the geolocation through a promise
        Geolocation.getCurrentPosition().then((position:Geoposition)=> {
            console.log(
                position.coords.latitude,
                position.coords.longitude);
        });
    }
}

Titta på positionen

För en mer realtidslösning kan du använda watchPosition-funktionen i Geolocation som meddelar när ett fel eller en positionsändring inträffar. Till skillnad från getCurrentPosition returnerar watchPosition en observerbar

import {Geolocation} from 'ionic-native';
import template from './custom-component.html';

@Component({
selector: 'custom-component',
template: template
})
export class CustomComponent {
constructor() {

    // get the geolocation through an observable
        Geolocation.watchPosition(<GeolocationOptions>{
            maximumAge: 5000, // a maximum age of cache is 5 seconds
            timeout: 10000, // time out after 10 seconds
            enableHighAccuracy: true // high accuracy 
        }).subscribe((position) => {
            console.log('Time:' + position.timestamp);
            console.log(
                'Position:' + position.coords.latitude + ',' +
                position.coords.longitude);
            console.log('Direction:' position.coords.heading);
            console.log('Speed:' position.coords.speed);

        });
}
