Vollständige Beispielanwendung lokal ausführen
Die Beispiel-App für das Maps SDK for iOS ist als Downloadarchiv auf GitHub verfügbar.
So installieren und testen Sie die Beispiel-App für das Maps SDK for iOS:
- Führen Sie
git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git
aus, um das Beispiel-Repository in ein lokales Verzeichnis zu klonen.
Öffnen Sie ein Terminalfenster, rufen Sie das Verzeichnis auf, in das Sie die Beispieldateien geklont haben, und wechseln Sie zum Verzeichnis „GoogleMaps“:
Swift
cd maps-sdk-for-ios-samples-main/GoogleMaps-Swift
pod install
open GoogleMapsSwiftDemos.xcworkspace
Objective-C
cd maps-sdk-for-ios-samples-main/GoogleMaps
pod install
open GoogleMapsDemos.xcworkspace
- Klicken Sie in Xcode auf die Schaltfläche „Kompilieren“, um die App mit dem aktuellen Schema zu erstellen. Beim Build wird ein Fehler ausgegeben, der Sie auffordert, Ihren API-Schlüssel in die Datei
SDKConstants.swift
für Swift oder SDKDemoAPIKey.h
für Objective-C einzugeben.
- Rufen Sie einen API-Schlüssel für Ihr Projekt ab, in dem das Maps SDK for iOS aktiviert ist.
- Bearbeite die
SDKConstants.swift
-Datei für Swift oder die SDKDemoAPIKey.h
-Datei für Objective-C und füge deinen API-Schlüssel in die Definition der Konstante apiKey
oder kAPIKey
ein. Beispiel:
Swift
static let apiKey = "YOUR_API_KEY"
Objective-C
static NSString *const kAPIKey = @"YOUR_API_KEY";
- Entfernen Sie in der Datei
SDKConstants.swift
(Swift) oder SDKDemoAPIKey.h
(Objective-C) die folgende Zeile, da sie zum Registrieren des benutzerdefinierten Problems verwendet wird:
Swift
#error (Register for API Key and insert here. Then delete this line.)
Objective-C
#error Register for API Key and insert here.
- Erstellen Sie das Projekt und führen Sie es aus. Das Fenster des iOS-Simulators wird angezeigt. Es enthält eine Liste der Maps SDK-Demos.
- Wählen Sie eine der angezeigten Optionen aus, um eine Funktion des Maps SDK for iOS zu testen.
- Wenn Sie aufgefordert werden, GoogleMapsDemos Zugriff auf Ihren Standort zu gewähren, wählen Sie Zulassen aus.

full sample app locally\n\nThe Maps SDK for iOS sample app is available as a\n[download archive](https://github.com/googlemaps-samples/maps-sdk-for-ios-samples/archive/main.zip)\nfrom [GitHub](https://github.com/googlemaps-samples/maps-sdk-for-ios-samples/tree/main/GoogleMaps).\nFollow these steps to install and try the Maps SDK for iOS sample app.\n\n1. Run `git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git` to clone the samples repository into a local directory.\n2. Open a terminal window, navigate to the directory where you cloned the sample files, and\n drill down into the GoogleMaps directory:\n\n Swift \n\n cd maps-sdk-for-ios-samples-main/GoogleMaps-Swift\n pod install\n open GoogleMapsSwiftDemos.xcworkspace\n\n Objective-C \n\n cd maps-sdk-for-ios-samples-main/GoogleMaps\n pod install\n open GoogleMapsDemos.xcworkspace\n\n3. In Xcode, press the compile button to [build the app](https://developer.apple.com/documentation/xcode/building-and-running-an-app) with the current scheme. The build produces an error, prompting you to enter your API key in the `SDKConstants.swift` file for Swift or`SDKDemoAPIKey.h` file for Objective-C.\n4. [Get an API key](/maps/documentation/ios-sdk/get-api-key) from your project with the [Maps SDK for iOS enabled](/maps/documentation/ios-sdk/cloud-setup#enabling-apis).\n5. Edit the `SDKConstants.swift` file for Swift or`SDKDemoAPIKey.h` file for Objective-C and paste your API key into the definition of either the `apiKey` or `kAPIKey` constant. For example: \n\n Swift \n\n ```scdoc\n static let apiKey = \"YOUR_API_KEY\"\n ```\n\n Objective-C \n\n ```objective-c\n static NSString *const kAPIKey = @\"YOUR_API_KEY\";\n ```\n6. In the `SDKConstants.swift` file (Swift) or`SDKDemoAPIKey.h` file (Objective-C), remove the following line, because it's used to register the user-defined issue: \n\n Swift \n\n ```text\n #error (Register for API Key and insert here. Then delete this line.)\n ```\n\n Objective-C \n\n ```text\n #error Register for API Key and insert here.\n ```\n7. Build and run the project. The iOS simulator window appears, showing a list of **Maps SDK Demos**.\n8. Choose one of the options displayed, to experiment with a feature of the Maps SDK for iOS.\n9. If prompted to allow GoogleMapsDemos to access your location, choose **Allow**."]]
