Step 1: Implement a sign-in experience

Introduction: Measure iOS Ads conversions
Step 1: Implement a sign-in experience
Step 2: Integrate Google Analytics
Step 3: Initiate on-device conversion measurement using Google Analytics
Step 4: Troubleshoot and handle common issues

The first step is to implement a sign-in experience to allow users to provide their email addresses or phone number.

The authentication system that you use must provide an email address or phone number associated with the user.The following steps outline the process for securely collecting sign-in information using Firebase Authentication , but you can skip this step if you already have an authentication system that collects user emails or phone numbers and continue to Step 2: Integrate Google Analytics .

Make sure you have the prerequisites for this tutorial

Your own app that can run on iOS 12 or higher
Your app registered as a Firebase App that's linked to Google Analytics and Ads
Your preferred IDE

handle = Auth . auth (). addStateDidChangeListener { auth , user in // Get the user's email address let email = user . email // or get their phone number let phoneNumber = user . phoneNumber // ... }

self . handle = [[ FIRAuth auth ] addAuthStateDidChangeListener : ^ ( FIRAuth * _Nonnull auth , FIRUser * _Nullable user ) { // Get the user's email address NSString * email = user . email ; // or get their phone number NSString * phoneNumber = user . phoneNumber ; // ... }];

Firebase . Auth . FirebaseAuth auth ; Firebase . Auth . FirebaseUser user ; // Handle initialization of the necessary firebase modules: void InitializeFirebase () { auth = Firebase . Auth . FirebaseAuth . DefaultInstance ; auth . StateChanged += AuthStateChanged ; AuthStateChanged ( this , null ); } // Track state changes of the auth object. void AuthStateChanged ( object sender , System . EventArgs eventArgs ) { if ( auth . CurrentUser != user ) { bool signedIn = user != auth . CurrentUser && auth . CurrentUser != null ; user = auth . CurrentUser ; if ( signedIn ) { // Get the user's email address string email = user . Email ; // or get their phone number string phoneNumber = user . PhoneNumber ; // ... } } } // Handle removing subscription and reference to the Auth instance. // Automatically called by a Monobehaviour after Destroy is called on it. void OnDestroy () { auth . StateChanged -= AuthStateChanged ; auth = null ; }
