NativeScript Geocoding apple android

npm npm

Forward-geocoding requests take a user-readable address and find the corresponding latitude and longitude value and may also return additional information about the specified location, such as a point of interest or building at that location.

Installation

In a command prompt / terminal navigate to your application root folder and run:

tns plugin add nativescript-geocoding

Usage

The best way to explore the usage of the plugin is to inspect the demo app in the plugin's root folder. In the demo-angular folder you can find the usage of the plugin for an Angular application (demo-angular/src/app/home/home.component.ts.

Steps:

Import the plugin

TypeScript

import * as geocoding from "nativescript-geocoding";

Javascript

var geocoding = require("nativescript-geocoding");

Call the plugin

  geocoding.getLocationFromName('Copenhagen').then(loc => {
      console.log('Found ', loc);
  }, function (e) {
      console.log("Error: " + (e.message || e));
  });

or in case you may want to treat possible, multiple hits

geocoding.getLocationListFromName(searchBar.text, 5).then(locations => {
            console.log('Found ', locations.length);
            if (locations.length > 0) {
                this.location = locations[0];
            }
        }, function (e) {
            console.log('Error: ' + (e.message || e));
        });

Demo

To run the Angular demo:

$ cd nativescript-geocoding/src
$ npm run demo.ios
$ npm run demo.android

Native APIs

Android implementation

Returns an array of Addresses that are known to describe the named location, which may be a place name such as "Dalvik, Iceland", an address such as "1600 Amphitheatre Parkway, Mountain View, CA", an airport code such as "SFO", etc.. The returned addresses will be localized for the locale provided to this class's constructor.

The query will block and returned values will be obtained by means of a network lookup. The results are a best guess and are not guaranteed to be meaningful or correct. It may be useful to call this method from a thread separate from your primary UI thread.

Parameters locationName String: a user-supplied description of a location maxResults int: max number of results to return. Smaller numbers (1 to 5) are recommended

iOS implementation

Depending on the precision of the user-provided information, you may receive one result or multiple results. For example, passing a string of "100 Main St., USA" may return many results unless you also specify a search region or additional details. To help you decide which result is correct, the geocoder actually returns CLPlacemark objects, which contain both the coordinate and the original information that you provided.

Notes

  • For Android, the minimum API level is 21 in order to get detailed location info.

  • On iOS you may receive this message

 Error: iOS CLGeocoder error : The operation couldn’t be completed. (kCLErrorDomain error 8.)

if the CLGeocoder was not able to find anything for the search string.
