Premiers pas avec le SDK Driver pour iOS

Utiliser CocoaPods

Pour configurer le SDK Driver à l'aide de CocoaPods, vous avez besoin des éléments suivants:

• L'outil CocoaPods: pour installer cet outil, ouvrez le terminal et exécutez la commande suivante. shell sudo gem install cocoapodsPour en savoir plus, consultez le guide de démarrage de CocoaPods.

1. Créez un fichier Podfile pour le SDK Driver et utilisez-le pour installer l'API et ses dépendances: créez un fichier nommé Podfile dans le répertoire de votre projet. Ce fichier définit les dépendances de votre projet. Modifiez le Podfile et ajoutez vos dépendances. Voici un exemple qui inclut les dépendances:

   source "https://github.com/CocoaPods/Specs.git"
   
   target 'YOUR_APPLICATION_TARGET_NAME_HERE' do
     pod 'GoogleRidesharingDriver'
   end
   

   Voici un exemple qui inclut les pods alpha et bêta du SDK du pilote en tant que dépendances:

   source "https://cpdc-eap.googlesource.com/ridesharing-driver-sdk.git"
   source "https://github.com/CocoaPods/Specs.git"
   
   target 'YOUR_APPLICATION_TARGET_NAME_HERE' do
     pod 'GoogleRidesharingDriver'
   end
   

2. Enregistrez le fichier Podfile. Ouvrez un terminal et accédez au répertoire contenant le fichier Podfile:

   cd <path-to-project>
   

3. Exécutez la commande d'installation du pod. Les API spécifiées dans le Podfile seront installées, ainsi que toutes les dépendances dont elles peuvent disposer.

   pod install
   

4. Fermez Xcode, puis ouvrez (double-cliquez) le fichier .xcworkspace de votre projet pour lancer Xcode. À partir de ce moment, vous devrez utiliser le fichier .xcworkspace pour ouvrir le projet.

Versions alpha/bêta des SDK

Pour configurer les versions alpha ou bêta du SDK Driver pour iOS, vous avez besoin des éléments suivants:

• L'outil CocoaPods: pour installer cet outil, ouvrez le terminal et exécutez la commande suivante.

  sudo gem install cocoapods
  

  Pour en savoir plus, consultez le guide de démarrage de CocoaPods.

• Votre compte de développement sur la liste d'accès Google. Le dépôt de pods des versions alpha et bêta du SDK n'est pas une source publique. Pour accéder à ces versions, contactez l'ingénieur client Google. L'ingénieur ajoute votre compte de développement à la liste d'accès, puis définit un cookie pour l'authentification.

Une fois que votre projet figure sur la liste d'accès, vous pouvez accéder au pod.
