After a user signs in with Google, you can get the user's basic profile information: their name, profile image URL, and email address.
Before you begin
Retrieving user information
Once the user has authenticated and authorized access to the scopes you request,
you can access user profile information through the GIDGoogleUser
object.
Swift
GIDSignIn.sharedInstance.signIn(withPresenting: self) { signInResult, error in
guard error == nil else { return }
guard let signInResult = signInResult else { return }
let user = signInResult.user
let emailAddress = user.profile?.email
let fullName = user.profile?.name
let givenName = user.profile?.givenName
let familyName = user.profile?.familyName
let profilePicUrl = user.profile?.imageURL(withDimension: 320)
}
Objective-C
[GIDSignIn.sharedInstance signInWithPresentingViewController:self
completion:^(GIDSignInResult * _Nullable signInResult,
NSError * _Nullable error) {
if (error) { return; }
if (signInResult == nil) { return; }
GIDGoogleUser *user = signInResult.user;
NSString *emailAddress = user.profile.email;
NSString *name = user.profile.name;
NSString *givenName = user.profile.givenName;
NSString *familyName = user.profile.familyName;
NSURL *profilePic = [user.profile imageURLWithDimension:320];
}];
