How to add a Cancel button on the WebView that doesn't prematurely closes the view

[Aziz Light]

Hi everybody,

I subclassed GTMOAuth2ViewControllerTouch to use my own xib file. I added a cancel button to the navigation controller linked to the view controller. The cancel button is linked to a method that dismisses the view controller. Here is that method:

- (void)dismissModalWebViewControllerUsingCancelButton:(UIControl *)sender

{

    [_modalWebViewController dismissViewControllerAnimated:YES completion:nil];

}

When I click on the cancel button I get the following error:

Error Domain=com.google.GTMOAuth2 Code=-1000 "The operation couldn’t be completed. (com.google.GTMOAuth2 error -1000.)"

I managed to make the error message disappear by modifying the method as follows:

- (void)dismissModalWebViewControllerUsingCancelButton:(UIControl *)sender

{

    [_modalWebViewController cancelSigningIn];

    [_modalWebViewController dismissViewControllerAnimated:YES completion:nil];

}

Now it works but the webview disappears without animation and then the navigation bar slides down and disappears. It's really ugly.

So the question is, how can I dismiss the view controller in an elegant way without getting any error messages please?

The error is intentional, indicating that the user did not sign in. The app should look for [error code] == kGTMOAuth2ErrorWindowClosed and [[error domain] isEqual:kGTMOAuth2ErrorDomain]
