Page Summary
-
This documentation outlines how to set up and use the Google Maps SDK for iOS to track and display trips in real-time within your application.
-
The guide covers initializing the map view, enabling user location, and handling events like the map becoming ready and marker taps.
-
You can customize the appearance of the map using styling options provided by the SDK, as well as follow a vehicle's trip progression with built-in features.
To set up a map to follow a trip in iOS, complete the following steps:
Step 1: Initialize the map view
To follow a trip, you must initialize a map view.
The following example shows how to initialize 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
Step 2: Handle map view events
Now that you've initialized the map view, here's how to implement a delegate to handle map view event changes as the vehicle progresses along its journey.
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.
}
