Determine if Google Sign-In is cancelled

[mr5z]

Hi, can we have a way of knowing if the Google auth is cancelled?
Right now, it just throws a generic Exception with a message:

"Error Domain=com.google.GIDSignIn Code=-5 "The user canceled the sign-in flow." UserInfo={NSLocalizedDescription=The user canceled the sign-in flow.}"

I am catching System.Threading.Tasks.TaskCanceledException in this case. Works for me.

@trevoriancox this is how I authenticate with Google:

try
{

OAuthApi api = ...

api.ResetData();
var account = await api.Authenticate();
if (!account.IsValid())
{
    return new DataResponse<AuthResponse>
    {
        ErrorType = HttpErrorType.Authentication
    };
}

var authAccount = account as OAuthAccount;

}
catch (Exception ex)
{

if (ex is TaskCanceledException)
{
    return new DataResponse<AuthResponse>
    {
        ErrorType = HttpErrorType.Cancelled
    };
}
// TODO hack. wait for the issue to be fixed
// https://github.com/Clancey/SimpleAuth/issues/101
if (ex.Message.Contains("com.google.GIDSignIn Code=-5"))
{
    ...
}

...

}

It does not go into if (ex is TaskCanceledException) part when I cancel the sign-in flow since I'm always receiving a generic type Exception where I need to make a hack.
