Untuk menyiapkan peta guna melacak perjalanan di iOS, selesaikan langkah-langkah berikut:
Langkah 1: Lakukan inisialisasi tampilan peta
Untuk mengikuti perjalanan, Anda harus melakukan inisialisasi tampilan peta.
Contoh berikut menunjukkan cara menginisialisasi GMTCMapView
.
Swift
/*
* MapViewController.swift
*/
class ViewController: UIViewController, GMTCMapViewDelegate {
private var rideSharingMap: GMTCMapView?
override func viewDidLoad() {
super.viewDidLoad()
self.rideSharingMap = GMTCMapView(frame: UIScreen.main.bounds)
self.rideSharingMap.delegate = self
self.rideSharingMap?.settings.myLocationButton = true
self.view.addSubview(self.rideSharingMap!)
...
}
}
Objective-C
/*
* MapViewController.h
*/
@interface MapViewController : UIViewController<GMTCMapViewDelegate>
...
@end
/*
* MapViewController.m
*/
@implementation MapViewController
- (void)viewDidLoad {
[super viewDidLoad];
...
self.mapView = [[GMTCMapView alloc] initWithFrame:CGRectZero];
self.mapView.settings.myLocationButton = YES;
self.mapView.delegate = self;
...
}
...
@end
Langkah 2: Menangani peristiwa tampilan peta
Setelah melakukan inisialisasi tampilan peta, berikut cara menerapkan delegasi untuk menangani perubahan peristiwa tampilan peta saat kendaraan bergerak di sepanjang perjalanannya.
Swift
func mapViewDidInitialize(_ mapview: GMTCMapView) {
// Handle the update to the state of the map view to browsing.
}
func mapView(_ mapView: GMSMapView, didTapConsumerMarker mapMarker: GMSMarker, markerType: GMTCMapViewMarkerType) -> Bool {
// Handle the mapView marker was tapped.
}
Objective-C
/*
* MapViewController.m
*/
#pragma mark - GMTCMapViewDelegate implementation
// Handle state update of map view.
- (void)mapViewDidInitializeCustomerState:(GMTCMapView *)mapview {
// Handle the update to the state of the map view to browsing.
}
- (void)mapView:(GMSMapView *)mapView
didTapConsumerMarker:(nonnull GMSMarker *)mapMarker
markerType:(GMTCMapViewMarkerType)markerType {
// Handle the mapView marker was tapped.
}
