Exécuter l'application exemple complète en local
L'application exemple du SDK Maps pour iOS est disponible en tant qu'archive de téléchargement sur GitHub.
Suivez ces étapes pour installer et essayer l'application exemple du SDK Maps pour iOS.
- Exécutez
git clone https://github.com/googlemaps-samples/maps-sdk-for-ios-samples.git
pour cloner le dépôt d'exemples dans un répertoire local.
Ouvrez une fenêtre de terminal, accédez au répertoire dans lequel vous avez cloné les exemples de fichiers, puis accédez au répertoire Google Maps:
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
- Dans Xcode, appuyez sur le bouton de compilation pour créer l'application avec le schéma actuel. La compilation génère une erreur et vous invite à saisir votre clé API dans le fichier
SDKConstants.swift
pour Swift ou le fichier SDKDemoAPIKey.h
pour Objective-C.
- Obtenez une clé API à partir de votre projet avec le SDK Maps pour iOS activé.
- Modifiez le fichier
SDKConstants.swift
pour Swift ou le fichier SDKDemoAPIKey.h
pour Objective-C, puis collez votre clé API dans la définition de la constante apiKey
ou kAPIKey
. Exemple :
Swift
static let apiKey = "YOUR_API_KEY"
Objective-C
static NSString *const kAPIKey = @"YOUR_API_KEY";
- Dans le fichier
SDKConstants.swift
(Swift) ou SDKDemoAPIKey.h
(Objective-C), supprimez la ligne suivante, car elle permet d'enregistrer le problème défini par l'utilisateur:
Swift
#error (Register for API Key and insert here. Then delete this line.)
Objective-C
#error Register for API Key and insert here.
- Créez et exécutez le projet. La fenêtre du simulateur iOS s'affiche, avec une liste de démonstrations du SDK Maps.
- Choisissez l'une des options affichées pour tester une fonctionnalité du SDK Maps pour iOS.
- Si vous êtes invité à autoriser GoogleMapsDemos à accéder à votre position, sélectionnez Autoriser.

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**."]]
