Google Maps SDK for iOS Utility Library

Description

This open-source library contains classes that are useful for a wide range of applications using the Google Maps SDK for iOS.

Requirements

Installation

  1. Include the GoogleMaps dependency using one of the available installation options (CocoaPods, XCFramework, Carthage (for v6.2.1 and earlier) or manual).

  2. Add this utility library using one of the methods below:

In your Podfile:

use_frameworks!

target 'TARGET_NAME' do
    pod 'Google-Maps-iOS-Utils', '4.2.2'
end

Replace TARGET_NAME and then, in the Podfile directory, type:

pod install

Note: This feature is only available with Swift 5.3 (Xcode 12) or later.

Add the following to your dependencies value of your Package.swift file.

dependencies: [
  .package(
    url: "https://github.com/googlemaps/google-maps-ios-utils.git",
    .upToNextMinor(from: "4.2.2")
  )
]

Usage

Clustering markers

import GoogleMaps
import GoogleMapsUtils

class MarkerClustering: UIViewController, GMSMapViewDelegate {
  private var mapView: GMSMapView!
  private var clusterManager: GMUClusterManager!

  override func viewDidLoad() {
    super.viewDidLoad()

    // Set up the cluster manager with the supplied icon generator and
    // renderer.
    let iconGenerator = GMUDefaultClusterIconGenerator()
    let algorithm = GMUNonHierarchicalDistanceBasedAlgorithm()
    let renderer = GMUDefaultClusterRenderer(mapView: mapView,
                                clusterIconGenerator: iconGenerator)
    clusterManager = GMUClusterManager(map: mapView, algorithm: algorithm,
                                                      renderer: renderer)

    // Register self to listen to GMSMapViewDelegate events.
    clusterManager.setMapDelegate(self)
    // ...
  }
  // ...
}

let markerArray = [marker1, marker2, marker3, marker4] // define your own markers
clusterManager.add(markerArray)

clusterManager.cluster()

Displaying KML data

import GoogleMaps
import GoogleMapsUtils

func renderKml() {
    // Parse KML
    let path: String = // Path to your KML file...
    let kmlUrl = URL(fileURLWithPath: path)
    let kmlParser = GMUKmlParser(url: kmlUrl)
    kmlParser.parse()

    // Render parsed KML
    let renderer = GMUGeometryRenderer(
        map: mapView,
        geometries: kmlParser.placemarks,
        styles: kmlParser.styles,
        styleMaps: kmlParser.styleMaps
    )
    renderer.render()
}
