Need a delegate for didDismiss

[benjaminhallock]

I will try to fork it and submit a pull request, but I really want to have a call back so I know when it was dismissed.

Why not just use the built in method setDidFinishDismissingCompletion

[self.popup setDidFinishDismissingCompletion:^{ //DO SOMETHING HERE WHEN THE POPUP IS DISMISSED }];
