Firmy i inne ciekawe miejsca

Domyślnie na mapie bazowej wyświetlają się ciekawe miejsca wraz z odpowiadającymi im ikonami. Obejmują one parki, szkoły, budynki administracji państwowej i inne. Dodatkowo biznesowe ważne miejsca są domyślnie wyświetlane na mapie, gdy jej typ to kGMSTypeNormal
. Punkty POI firm to np. sklepy, restauracje, hotele itp.
Punkt POI odpowiada identyfikatorowi miejsca zdefiniowanemu w pakiecie SDK Miejsc na iOS. Na przykład parki rekreacyjne są ważnymi miejscami, ale takie obiekty jak fontanny zwykle nie są (chyba że mają znaczenie krajowe lub historyczne).
Nasłuchiwanie zdarzeń kliknięcia w przypadku ważnych miejsc
Jeśli chcesz reagować na kliknięcia punktu POI przez użytkownika, zaimplementuj GMSMapViewDelegate
i metodę mapView(_:didTapPOIWithPlaceID:name:location:)
, jak pokazano w tym przykładzie:
Swift
import GoogleMaps
class POI: UIViewController, GMSMapViewDelegate {
override func loadView() {
let camera = GMSCameraPosition.camera(
withLatitude: 47.603,
longitude:-122.331,
zoom:14
)
let mapView = GMSMapView.map(withFrame: .zero, camera: camera)
mapView.delegate = self
self.view = mapView
}
func mapView(
_ mapView: GMSMapView,
didTapPOIWithPlaceID placeID: String,
name: String,
location: CLLocationCoordinate2D
) {
print("You tapped \(name): \(placeID), \(location.latitude)/\(location.longitude)")
}
}
Objective-C
#import "POI.h"
@import GoogleMaps;
@interface POI () <GMSMapViewDelegate>
@end
@implementation POI
- (void)loadView {
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:47.603
longitude:-122.331
zoom:14];
GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView.delegate = self;
self.view = mapView;
}
#pragma mark - GMSMapViewDelegate
- (void)mapView:(GMSMapView *)mapView
didTapPOIWithPlaceID:(NSString *)placeID
name:(NSString *)name
location:(CLLocationCoordinate2D)location {
NSLog(@"You tapped %@: %@, %f/%f", name, placeID, location.latitude, location.longitude);
}
@end
Wyświetlanie szczegółów w oknie informacji
Punkty POI są domyślnie wyświetlane na mapie, ale nie ma domyślnego interfejsu kliknięcia (interfejs API nie wyświetla automatycznie okna informacji ani żadnego innego interfejsu użytkownika, gdy użytkownik kliknie punkt POI). Poniższy przykład pokazuje, jak użyć markera do wyświetlenia okna informacyjnego dla punktu POI:
Swift
// Declare GMSMarker instance at the class level.
let infoMarker = GMSMarker()
// Attach an info window to the POI using the GMSMarker.
func mapView(
_ mapView: GMSMapView,
didTapPOIWithPlaceID placeID: String,
name: String,
location: CLLocationCoordinate2D
) {
infoMarker.snippet = placeID
infoMarker.position = location
infoMarker.title = name
infoMarker.opacity = 0;
infoMarker.infoWindowAnchor.y = 1
infoMarker.map = mapView
mapView.selectedMarker = infoMarker
}
Objective-C
// Declare a GMSMarker instance at the class level.
GMSMarker *infoMarker;
// Attach an info window to the POI using the GMSMarker.
- (void)mapView:(GMSMapView *)mapView
didTapPOIWithPlaceID:(NSString *)placeID
name:(NSString *)name
location:(CLLocationCoordinate2D)location {
infoMarker = [GMSMarker markerWithPosition:location];
infoMarker.snippet = placeID;
infoMarker.title = name;
infoMarker.opacity = 0;
CGPoint pos = infoMarker.infoWindowAnchor;
pos.y = 1;
infoMarker.infoWindowAnchor = pos;
infoMarker.map = mapView;
mapView.selectedMarker = infoMarker;
}
Wyłączanie wyświetlania ciekawych miejsc na mapie
Możesz ukryć punkty POI, stosując style niestandardowe do wszystkich punktów POI lub do określonych kategorii punktów POI.
Poniższa deklaracja stylu JSON ukrywa wszystkie punkty POI firm na mapie:
[
{
"featureType": "poi.business",
"stylers": [
{ "visibility": "off" }
]
}
]
Inny przykład: poniższy kod JSON upraszcza wyświetlanie wszystkich kategorii
punktów POI:
[
{
"featureType": "poi",
"stylers": [
{ "visibility": "simplified" }
]
}
]
Więcej informacji znajdziesz w przewodniku po ukrywaniu elementów mapy za pomocą stylów.

POIs include parks, schools, government buildings, and\nmore. In addition, *business* POIs appear by default on the map when the map\ntype is `kGMSTypeNormal`. Business POIs represent businesses such as shops,\nrestaurants, hotels, and more.\n\nA POI corresponds to a [Place ID](/maps/documentation/places/ios-sdk/place-id#id-overview),\nas defined in the Places SDK for iOS. For example, recreational parks are POIs,\nbut things like water fountains are generally not POIs (unless they're of\nnational or historic significance).\n\nListening for click events on POIs\n\nIf you want to respond to a user tapping on a POI, implement\n[`GMSMapViewDelegate`](/maps/documentation/ios-sdk/reference/objc/Protocols/GMSMapViewDelegate),\nand implement the\n[`mapView(_:didTapPOIWithPlaceID:name:location:)`](/maps/documentation/ios-sdk/reference/objc/Protocols/GMSMapViewDelegate#-mapview:didtappoiwithplaceid:name:location:)\nmethod, as shown in the following example:\n\n\nSwift \n\n```swift\nimport GoogleMaps\n\nclass POI: UIViewController, GMSMapViewDelegate {\n\n override func loadView() {\n let camera = GMSCameraPosition.camera(\n withLatitude: 47.603,\n longitude:-122.331,\n zoom:14\n )\n let mapView = GMSMapView.map(withFrame: .zero, camera: camera)\n mapView.delegate = self\n self.view = mapView\n }\n\n func mapView(\n _ mapView: GMSMapView,\n didTapPOIWithPlaceID placeID: String,\n name: String,\n location: CLLocationCoordinate2D\n ) {\n print(\"You tapped \\(name): \\(placeID), \\(location.latitude)/\\(location.longitude)\")\n }\n}\n \n```\n\nObjective-C \n\n```objective-c\n#import \"POI.h\"\n@import GoogleMaps;\n\n@interface POI () \u003cGMSMapViewDelegate\u003e\n\n@end\n\n@implementation POI\n\n- (void)loadView {\n GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:47.603\n longitude:-122.331\n zoom:14];\n GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];\n mapView.delegate = self;\n self.view = mapView;\n}\n\n#pragma mark - GMSMapViewDelegate\n\n- (void)mapView:(GMSMapView *)mapView\n didTapPOIWithPlaceID:(NSString *)placeID\n name:(NSString *)name\n location:(CLLocationCoordinate2D)location {\n NSLog(@\"You tapped %@: %@, %f/%f\", name, placeID, location.latitude, location.longitude);\n}\n\n@end\n \n```\n\n\u003cbr /\u003e\n\nShowing details in an info window\n\nPOIs appear on the map by default, but there is no default on-click UI (the API\ndoes not automatically display an info window or any other user interface when\nthe user taps a POI). The following example shows how to use a marker to\ndisplay an info window for a POI:\n\n\nSwift \n\n```swift\n// Declare GMSMarker instance at the class level.\nlet infoMarker = GMSMarker()\n\n// Attach an info window to the POI using the GMSMarker.\nfunc mapView(\n _ mapView: GMSMapView,\n didTapPOIWithPlaceID placeID: String,\n name: String,\n location: CLLocationCoordinate2D\n) {\n infoMarker.snippet = placeID\n infoMarker.position = location\n infoMarker.title = name\n infoMarker.opacity = 0;\n infoMarker.infoWindowAnchor.y = 1\n infoMarker.map = mapView\n mapView.selectedMarker = infoMarker\n}\n \n```\n\nObjective-C \n\n```objective-c\n// Declare a GMSMarker instance at the class level.\nGMSMarker *infoMarker;\n\n// Attach an info window to the POI using the GMSMarker.\n- (void)mapView:(GMSMapView *)mapView\n didTapPOIWithPlaceID:(NSString *)placeID\n name:(NSString *)name\n location:(CLLocationCoordinate2D)location {\n infoMarker = [GMSMarker markerWithPosition:location];\n infoMarker.snippet = placeID;\n infoMarker.title = name;\n infoMarker.opacity = 0;\n CGPoint pos = infoMarker.infoWindowAnchor;\n pos.y = 1;\n infoMarker.infoWindowAnchor = pos;\n infoMarker.map = mapView;\n mapView.selectedMarker = infoMarker;\n}\n \n```\n\n\u003cbr /\u003e\n\nStopping POIs from showing on the map\n\nYou can hide POIs by applying custom styles to all POIs or\nto specific categories of POIs.\n\nThe following JSON style declaration hides all business POIs on the map: \n\n [\n {\n \"featureType\": \"poi.business\",\n \"stylers\": [\n { \"visibility\": \"off\" }\n ]\n }\n ]\n\nAs another example, the following JSON simplifies the display of all categories\nof POIs: \n\n [\n {\n \"featureType\": \"poi\",\n \"stylers\": [\n { \"visibility\": \"simplified\" }\n ]\n }\n ]\n\nFor more details, see the guide to [hiding map features with styling](/maps/documentation/ios-sdk/hiding-features)."]]
