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)."]]
