Introduzione all'SDK Driver per iOS

Utilizzare CocoaPods

Per configurare l'SDK Driver utilizzando CocoaPods, devi disporre dei seguenti elementi:

• Strumento CocoaPods: per installare questo strumento, apri il terminale ed esegui questo comando. shell sudo gem install cocoapods Per ulteriori dettagli, consulta la Guida introduttiva a CocoaPods.

1. Creare un Podfile per l'SDK Driver e utilizzarlo per installare l'API e le sue dipendenze: creare un file denominato Podfile nella directory del progetto. Questo file definisce le dipendenze del progetto. Modifica il Podfile e aggiungi le tue dipendenze. Ecco un esempio che include le dipendenze:

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

   Ecco un esempio che include i pod alpha e beta per l'SDK Driver come dipendenze:

   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. Salva il podfile. Apri un terminale e vai alla directory contenente il podfile:

   cd <path-to-project>
   

3. Esegui il comando di installazione del pod. Verranno installate le API specificate nel podfile, insieme alle eventuali dipendenze.

   pod install
   

4. Chiudi Xcode, quindi apri (fai doppio clic) sul file .xcworkspace del progetto per avviare Xcode. Da questo momento in poi, devi utilizzare il file .xcworkspace per aprire il progetto.

Installa XCFramework

Un XCFramework è un pacchetto binario che utilizzi per installare l'SDK Driver. Puoi utilizzare questo pacchetto su più piattaforme, incluse le macchine che utilizzano il chipset M1. Questa guida mostra come aggiungere manualmente al progetto l'SDK XCFramework contenente l'SDK Driver e configurare le impostazioni di build in Xcode.

1. Decomprimi i file di origine che hai ricevuto da Google.

2. Avvia Xcode e apri un progetto esistente oppure creane uno nuovo. Se non hai mai utilizzato iOS, crea un nuovo progetto e seleziona il modello dell'app per iOS.

3. Crea un gruppo di framework nel gruppo di progetto se non ne esiste già uno.

4. Trascina il file gRPCCertificates.bundle incluso nella directory Resources del file ZIP contenente l'elemento XCFramework nella directory di primo livello del tuo progetto Xcode. Quando richiesto, seleziona Copia elementi, se necessario.

5. Per installare l'SDK Driver, trascina il file GoogleRidesharingDriver.xcframework nel progetto in Frameworks, Libraries, and Embedded Content. Quando richiesto, seleziona Copia elementi, se necessario.

6. Seleziona il progetto nella barra di navigazione del progetto e scegli il target dell'applicazione.

7. Apri la scheda Fasi di build e, in Link Binary with Libraries, aggiungi i seguenti framework e librerie se non sono già presenti:

   • Accelerate.framework
   • AudioToolbox.framework
   • AVFoundation.framework
   • CoreData.framework
   • CoreGraphics.framework
   • CoreLocation.framework
   • CoreTelephony.framework
   • CoreText.framework
   • GLKit.framework
   • ImageIO.framework
   • libc++.tbd
   • libxml2.tbd
   • libz.tbd
   • OpenGLES.framework
   • QuartzCore.framework
   • SystemConfiguration.framework
   • UIKit.framework
   • LocalAuthentication.framework
   • WebKit.framework

8. Scegli il progetto anziché un target specifico e apri la scheda Impostazioni build. Nella sezione Altri linker, aggiungi ‑ObjC sia per il debug sia per la release. Se queste impostazioni non sono visibili, modifica il filtro nella barra Impostazioni build da Di base a Tutte.

Versioni SDK alpha/beta

Per configurare le versioni alpha o beta dell'SDK Driver per iOS, devi disporre dei seguenti elementi:

• Strumento CocoaPods: per installare questo strumento, apri il terminale ed esegui questo comando.

  sudo gem install cocoapods
  

  Per ulteriori dettagli, consulta la Guida introduttiva a CocoaPods.

• Il tuo account di sviluppo nell'elenco di accesso di Google. Il repository di pod delle versioni alpha e beta dell'SDK non è di origine pubblica. Per accedere a queste versioni, contatta il Customer Engineer di Google. Il tecnico aggiunge il tuo account di sviluppo all'elenco per gli accessi e poi imposta un cookie per l'autenticazione.

Una volta che il progetto è nell'elenco di accesso, puoi accedere al pod.

1. Creare un podfile per l'SDK Delivery per iOS e utilizzarlo per installare l'API e le sue dipendenze: crea un file denominato Podfile nella directory del progetto. Questo file definisce le dipendenze del progetto. Modifica il Podfile e aggiungi le tue dipendenze. Ecco un esempio che include le dipendenze:

   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. Salva il podfile. Apri un terminale e vai alla directory contenente il podfile:

   cd <path-to-project>
   

3. Esegui il comando di installazione del pod. Questo comando installa le API specificate nel podfile, insieme alle eventuali dipendenze.

   pod install
   

4. Chiudi Xcode, quindi apri (fai doppio clic) sul file .xcworkspace del progetto per avviare Xcode. Da questo momento in poi, devi utilizzare il file .xcworkspace per aprire il progetto.
