משתמשים במחלקת המשנה GMSAdvancedMarker כדי ליצור תכונות בסיסיות או ספציפיות של סמנים, כמו שמוצג בהמשך. בתור מחלקת משנה של GMSMarker, GMSAdvancedMarker מספקת סמנים עם יותר ביטויים.
בדומה ל-GMSMarker, אפשר להסיר סמן מתקדם מהמפה על ידי הגדרת מאפיין המפה של GMSAdvancedMarker ל-nil. לחלופין, אפשר להסיר את כל שכבות העל (כולל סמנים מתקדמים) במפה על ידי קריאה לשיטה GMSMapViewclear.
אם רוצים לבצע שינויים בסמן אחרי שמוסיפים אותו למפה, צריך לוודא ששומרים את האובייקט GMSAdvancedMarker. אפשר לשנות את הסמן מאוחר יותר על ידי שינוי האובייקט הזה.
המאפיין mapCapabilities ב-GMSMapView מוסיף בדיקה תוכנתית של תכונות ספציפיות למפה. השיטה הזו שימושית כשרוצים לדעת אם יכולות מסוימות של המפה זמינות לפני שמפעילים ממשקי API ספציפיים. הפונקציה didChangeMapCapabilities של GMSMapViewDelegateמופעלת גם כשמשתנים היכולות.
השאילתה הזו קובעת אם תצוגת המפה תומכת בסמנים מתקדמים.

As a subclass of\n[`GMSMarker`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMarker), `GMSAdvancedMarker` provides markers with more\nexpression. \n\n### Swift\n\n```swift\nlet camera = GMSCameraPosition( target: coordinate, zoom: 14)\nlet mapID = GMSMapID(identifier: \"YOUR_MAP_ID\")\nlet mapView = GMSMapView(frame: view.bounds, mapID: mapID, camera: camera)\n\nlet marker = GMSAdvancedMarker(position: coordinate)\nmarker.map = mapView\n```\n\n### Objective-C\n\n```objective-c\nGMSCameraPosition *camera = [GMSCameraPosition cameraWithTarget:kCoordinate zoom:16];\nGMSMapID *mapID = [GMSMapID mapIDWithIdentifier:\"YOUR_MAP_ID\"];\n\nself.mapView = [GMSMapView mapWithFrame:self.view.bounds mapID:mapID camera:camera];\n\nGMSAdvancedMarker *marker = [GMSAdvancedMarker markerWithPosition:kCoordinate];\nMarker.map = self.mapView;\n```\n| Note: For testing, you can skip the step of creating and configuring a [map ID](/maps/documentation/get-map-id), by using mapId: `DEMO_MAP_ID` in your app code. `DEMO_MAP_ID` is intended for testing purposes only. Don't use `DEMO_MAP_ID` in a production environment.\n\nRemove an advanced marker\n-------------------------\n\nSimilar to [`GMSMarker`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMarker), you can remove an advanced marker from the\nmap by setting the map property of the [`GMSAdvancedMarker`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSAdvancedMarker)\nto `nil`. Alternatively, you can remove all of the overlays (including advanced\nmarkers) on the map by calling the [`GMSMapView`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMapView) `clear` method.\n\n\n### Swift\n\n```swift\nlet camera = GMSCameraPosition.camera(\n withLatitude: -33.8683,\n longitude: 151.2086,\n zoom: 6\n)\nlet mapView = GMSMapView.map(withFrame: .zero, camera: camera)\n// ...\nmapView.clear()\n \n```\n\n### Objective-C\n\n```objective-c\nGMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683\n longitude:151.2086\n zoom:6];\nmapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];\n// ...\n[mapView clear];\n \n```\n\n\u003cbr /\u003e\n\nIf you want to make modifications to a marker after you've added it to the map,\nensure that you keep hold of the [`GMSAdvancedMarker`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSAdvancedMarker)\nobject. You can modify the marker later by making changes to this object. \n\n### Swift\n\n```swift\nlet position = CLLocationCoordinate2D(latitude: 10, longitude: 10)\nlet marker = GMSAdvancedMarker(position: position)\nmarker.map = mapView\n// ...\nmarker.map = nil\n```\n\n### Objective-C\n\n```objective-c\nCLLocationCoordinate2D position = CLLocationCoordinate2DMake(10, 10);\nGMSAdvancedMarker *marker = [GMSAdvancedMarker markerWithPosition:position];\nmarker.map = mapView;\n// ...\nmarker.map = nil;\n```\n\nMap capabilities\n----------------\n\nThe `mapCapabilities` property on [`GMSMapView`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSMapView) adds programmatic\nchecking for map-specific features. This is useful when wanting to know if\ncertain map capabilities are available before calling specific APIs. The\n`didChangeMapCapabilities` function of\n[`GMSMapViewDelegate`](/maps/documentation/ios-sdk/reference/objc/Protocols/GMSMapViewDelegate) is also\n[invoked](/maps/documentation/ios-sdk/marker-gestures) as capabilities change.\nThis query determines if the map view supports advanced markers. \n\n### Swift\n\n```swift\n// ...\n\nlet advancedMarker: GMSAdvancedMarker = {\nGMSAdvancedMarker(position: CLLocationCoordinate2D(latitude: 47.6089945, longitude: -122.3410462))\n}()\n\nlet marker: GMSMarker = {\nGMSMarker(position: CLLocationCoordinate2D(latitude: 47.6089945, longitude: -122.3410462))\n}()\n\nfunc addMarker() {\n if mapView.mapCapabilities.contains(.advancedMarkers) {\n advancedMarker.map = mapView\n } else {\n marker.map = mapView\n }\n}\n\nextension MapCapabilities: GMSMapViewDelegate {\n func mapView(_ mapView: GMSMapView, didChangeMapCapabilities mapCapabilities: GMSMapCapabilityFlags) {\n\n let advancedMarkerAvailable = mapCapabilities.contains(.advancedMarkers)\n\n advancedMarker.map = advancedMarkerAvailable ? mapView : nil\n marker.map = advancedMarkerAvailable ? nil : mapView\n }\n}\n```\n\n### Objective-C\n\n```objective-c\n// ...\n\n_advancedMarker = [GMSAdvancedMarker markerWithPosition: kSeattleCoordinates];\n_fallbackMarker = [GMSMarker markerWithPosition: kSeattleCoordinates];\n\n- (void)addMarker {\n\n if (_mapView.mapCapabilities & GMSMapCapabilityFlagsAdvancedMarkers) {\n _advancedMarker.map = _mapView;\n } else {\n _fallbackMarker.map = _mapView;\n }\n}\n\n#pragma mark - GMSMapViewDelegate\n\n- (void)mapView:(GMSMapView *)mapView\n didChangeMapCapabilities:(GMSMapCapabilityFlags)mapCapabilities {\n BOOL advancedMarkersAvailable = mapCapabilities & GMSMapCapabilityFlagsAdvancedMarkers;\n _advancedMarker.map = advancedMarkersAvailable ? _mapView : nil;\n _fallbackMarker.map = advancedMarkersAvailable ? nil : _mapView;\n}\n```"]]
