Halaman ini menunjukkan cara merender data geografis dalam KML
format, menggunakan GMUKMLParser dalam
bersama dengan GMUGeometryRenderer. KML adalah perangkat
format untuk merender data geografis seperti titik, garis, dan poligon.
Screenshot berikut menampilkan beberapa contoh data KML yang dirender pada peta:

Merender data KML
Untuk merender data KML pada peta, buat GMUKMLParser dengan elemen
ke resource KML (dalam contoh ini KML_Sample.kml). Lalu:
buat GMUGeometryRenderer dengan meneruskan GMUKMLParser
di instance Compute Engine. Terakhir, panggil GMUGeometryRenderer.render(). Tujuan
contoh kode berikut menunjukkan rendering data KML pada peta:

KML is a popular\nformat for rendering geographic data such as points, lines, and polygons.\n\nThe following screenshot shows some example KML data rendered on a map:\n\nPrerequisites and notes\n\n`GMUKMLParser` is part of\nthe [Maps SDK for iOS Utility Library](https://github.com/googlemaps/google-maps-ios-\nutils). If you haven't yet set up\nthe library, follow the [setup guide](/maps/documentation/ios-\nsdk/utility/setup) before reading the rest of this page.\n\nFor the full code sample, see the sample apps\n[on\nGitHub](https://github.com/googlemaps/google-maps-ios-utils).\n\nRendering KML data\n\nTo render KML data on a map, create a `GMUKMLParser` with the\npath to a KML resource (`KML_Sample.kml` in this example). 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```"]]
