Kamera memungkinkan Anda mengubah sudut pandang pengguna terhadap peta. Anda dapat menggunakan mode kamera untuk mengontrol perilaku
peta selama navigasi. Untuk menyetel mode kamera, tetapkan properti cameraMode
tampilan peta, dengan menentukan salah satu konstanta mode kamera berikut:
Mengikuti — Mode kamera default untuk navigasi. Mengubah sudut pandang menjadi 45 derajat dan menempatkan kamera di belakang posisi saat ini yang menghadap ke arah perjalanan. Selama navigasi, kamera akan otomatis menyesuaikan
untuk menghadap ke arah perjalanan. Menekan tombol Pusatkan ulang peta
juga akan beralih ke mode ini. Tombol Pusatkan ulang tidak terlihat saat
mode ini dipilih.
Ringkasan — Menampilkan ringkasan seluruh rute, melakukan zoom sesuai kebutuhan
agar rute sesuai dengan tampilan peta. Saat tampilan ini dipilih, tombol
Pusatkan ulang akan terlihat.
Gratis — Memungkinkan pengguna mengubah tampilan peta dengan gestur.
Kamera tetap diam dalam tampilan ini. Peta akan otomatis memasuki
tampilan ini jika pengguna menggeser atau melakukan zoom selama navigasi. Saat tampilan ini dipilih, tombol Pusatkan kembali akan terlihat.
Untuk mengubah mode kamera, tetapkan properti cameraMode
tampilan peta, seperti yang ditunjukkan di sini:
Swift
// Set the mode to "overview":
mapView.cameraMode = .overview
// Set the mode to "free":
mapView.cameraMode = .free
// Set the mode to "following":
mapView.cameraMode = .following
Objective-C
// Set the mode to "overview":
mapView.cameraMode = GMSNavigationCameraModeOverview;
// Set the mode to "free":
mapView.cameraMode = GMSNavigationCameraModeFree;
// Set the mode to "following":
mapView.cameraMode = GMSNavigationCameraModeFollowing;
Memusatkan ulang peta secara otomatis
Saat pengguna memindahkan peta dalam mode Navigasi, mode kamera untuk tampilan peta berubah dari mode mengikuti ke mode bebas. Kamera kembali ke mode
mengikuti saat pengguna menekan Pusatkan ulang secara eksplisit. Anda dapat mengotomatiskan
kembali ke mode mengikuti dengan menggunakan timer untuk menyetel interval antara keluar dari
mode mengikuti, lalu otomatis kembali ke mode tersebut.
Contoh
Contoh kode berikut memeriksa untuk menentukan apakah peta dipindahkan oleh pengguna saat dalam mode Navigasi. Jika ya, timer akan disetel untuk mengalihkan mode kamera ke mode mengikuti, memusatkan peta setelah lima detik.

You can use camera modes to control the behavior of the\nmap during navigation. To set the camera mode, set the `cameraMode` property of\nthe map view, specifying one of the following camera mode constants:\n\n- Following --- The default camera mode for navigation. Changes the view\n angle to 45 degrees and puts the camera behind the current position facing in\n the direction of travel. During navigation the camera automatically adjusts\n to face in the direction of travel. Pressing the map's **Re-center** button\n will also switch to this mode. The **Re-center** button is not visible when\n this mode is selected.\n\n- Overview --- Displays an overview of the entire route, zooming as needed\n to fit the route into the map view. When this view is selected the\n **Re-center** button is visible.\n\n- Free --- Lets the user change the map view with [gestures](/maps/documentation/navigation/ios-sdk/controls).\n The camera remains stationary in this view. The map will automatically enter\n this view if the user pans or zooms during navigation. When this view is\n selected the **Re-center** button is visible.\n\nTo change the camera mode, set the `cameraMode` property of the map view, as\nshown here:\n\n\u003cbr /\u003e\n\n### Swift\n\n\u003cbr /\u003e\n\n // Set the mode to \"overview\":\n mapView.cameraMode = .overview\n\n // Set the mode to \"free\":\n mapView.cameraMode = .free\n\n // Set the mode to \"following\":\n mapView.cameraMode = .following\n\n\u003cbr /\u003e\n\n### Objective-C\n\n\u003cbr /\u003e\n\n // Set the mode to \"overview\":\n mapView.cameraMode = GMSNavigationCameraModeOverview;\n\n // Set the mode to \"free\":\n mapView.cameraMode = GMSNavigationCameraModeFree;\n\n // Set the mode to \"following\":\n mapView.cameraMode = GMSNavigationCameraModeFollowing;\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nAutomatically recenter the map\n------------------------------\n\nWhen users move the map in Navigation mode, the camera mode for the map\nview changes from following mode to free mode. The camera returns to following\nmode when the user explicitly presses **Re-center**. You can automate the\nreturn to following mode by using a timer to set an interval between leaving\nfollowing mode, and then automatically returning to it.\n\n### Example\n\nThe following code example checks to determine whether the map is being moved by\nthe user while in Navigation mode. If it is, then it sets a timer to switch the\ncamera mode to following mode, centering the map after five seconds.\n\n\u003cbr /\u003e\n\n### Swift\n\n\u003cbr /\u003e\n\n class YourViewController: UIViewController {\n\n @IBOutlet weak var mapView: GMSMapView!\n var autoFollowTimer: Timer!\n\n override func viewDidLoad() {\n super.viewDidLoad()\n mapView.delegate = self\n ...\n }\n\n ...\n }\n\n /** Implements the GMSMapViewDelegate protocol. */\n extension YourViewController: GMSMapViewDelegate {\n func mapView(_ mapView: GMSMapView, willMove gesture: Bool) {\n if mapView.navigator?.isGuidanceActive == false {return}\n if !gesture {return}\n\n autoFollowTimer?.invalidate()\n autoFollowTimer = Timer(\n timeInterval: TimeInterval(5.0),\n target: self,\n selector: #selector(recenterMap),\n userInfo: nil,\n repeats: false)\n RunLoop.current.add(autoFollowTimer, forMode: .default)\n }\n\n /** Centers the map in guidance mode. */\n @objc private func recenterMap() {\n if mapView.navigator?.isGuidanceActive == true {\n mapView.cameraMode = .following\n }\n\n autoFollowTimer.invalidate()\n autoFollowTimer = nil\n }\n }\n\n\u003cbr /\u003e\n\n### Objective-C\n\n\u003cbr /\u003e\n\n @interface YourViewController : UIViewController\u003cGMSMapViewDelegate\u003e\n ...\n @end\n\n\n @implementation YourViewController {\n GMSMapView *_mapView;\n NSTimer *_autoFollowTimer;\n ...\n }\n\n ...\n\n - (void)viewDidLoad {\n [super viewDidLoad];\n ...\n _mapView.delegate = self;\n ...\n }\n\n ...\n\n /** Implements the GMSMapViewDelegate protocol. */\n - (void)mapView:(GMSMapView *)mapView willMove:(BOOL)gesture {\n if (!_mapView.navigator.guidanceActive) return;\n if (!gesture) return;\n\n [_autoFollowTimer invalidate];\n _autoFollowTimer = [NSTimer scheduledTimerWithTimeInterval:5.0\n target:self\n selector:@selector(recenterMap)\n userInfo:nil\n repeats:NO];\n }\n\n /** Centers the map in guidance mode. */\n - (void)recenterMap {\n if (_mapView.navigator.guidanceActive) {\n _mapView.cameraMode = GMSNavigationCameraModeFollowing;\n }\n\n [_autoFollowTimer invalidate];\n _autoFollowTimer = nil;\n }\n\n @end\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e"]]
