I am authenticating our web service using ASWebAuthenticationSession and for some reason the only option after the final redirect is Cancel. I had this working before where even if I did press Cancel, the callback Url was sent through the completion handler and I was able to parse the token form there. But now I just get the error ASWebAuthenticationSessionErrorCodeCanceledLogin.
How do I get the ASWebAuthenticationSession to show the Done button and complete the handler with the callback Url? Did something change or break in the last iOS update?
How I create the session
if (@available(iOS 12.0, *)) {
self.session = [[ASWebAuthenticationSession alloc]
initWithURL:@"http://service.com"
callbackURLScheme:@"http://website.com"
completionHandler:_sessionHandler];
[self.session start];
}
Completion handler
_sessionHandler = ^(NSURL * _Nullable callbackURL, NSError * _Nullable error) {
NSLog(@"Callback Url: %@, Error: %@", callbackURL, error);
if ( callbackURL != nil ) {
__block NSString * token = [weakSelf webToken:@"token" fromUrl:callbackURL];
weakSelf.completionHandler([weakSelf parseWebToken:token], error);
}
else
weakSelf.completionHandler(nil, error);
};
The output
Callback Url: (null), Error: Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=1 "(null)"
Like I mentioned, this worked previously and I am not sure where it broke. The test service I used has not changed, so I am wondering if it is in the framework, or if I am missing something else.
Should the web service be sending a specific header back to the final Url so ASWebAuthenticationSession will show the Done button and complete the handler with the Url?
