KML-Daten rendern
Um KML-Daten auf einer Karte zu rendern, erstellen Sie eine GMUKMLParser mit dem
Pfad zu einer KML-Ressource (in diesem Beispiel KML_Sample.kml). Gehen Sie dann so vor:
ein GMUGeometryRenderer erstellen und die GMUKMLParser übergeben
Instanz. Rufen Sie schließlich GMUGeometryRenderer.render() auf. Die

Then,\ncreate a `GMUGeometryRenderer` passing the `GMUKMLParser`\ninstance. Finally, call `GMUGeometryRenderer.render()`. The\nfollowing code example shows rendering KML data on a map: \n\nSwift \n\n```swift\nimport GoogleMapsUtils\n\nclass KML: NSObject {\n private var mapView: GMSMapView!\n\n func renderKml() {\n guard let path = Bundle.main.path(forResource: \"KML_Sample\", ofType: \"kml\") else {\n print(\"Invalid path\")\n return\n }\n\n let url = URL(fileURLWithPath: path)\n\n let kmlParser = GMUKMLParser(url: url)\n kmlParser.parse()\n\n let renderer = GMUGeometryRenderer(\n map: mapView,\n geometries: kmlParser.placemarks,\n styles: kmlParser.styles\n )\n\n renderer.render()\n }\n}\n \n```\n\nObjective-C \n\n```objective-c\n@import GoogleMapsUtils;\n\n@implementation KML {\n GMSMapView *_mapView;\n}\n\n- (void)renderKml {\n NSString *path = [[NSBundle mainBundle] pathForResource:@\"KML_Sample\" ofType:@\"kml\"];\n NSURL *url = [NSURL fileURLWithPath:path];\n GMUKMLParser *parser = [[GMUKMLParser alloc] initWithURL:url];\n [parser parse];\n GMUGeometryRenderer *renderer = [[GMUGeometryRenderer alloc] initWithMap:_mapView\n geometries:parser.placemarks\n styles:parser.styles];\n [renderer render];\n}\n\n@end\n \n```"]]
