Could somone help: I have situation where I'm calling a LoginViewController from my main ViewController and then via a delegate in the LoginViewcontroller calling back a function that fires off "self.dismissViewcontrolleranimated(view, animated: false, completion: nil) but the modal popup viewController just keeps poping back. Can anyone tell me what I have wrong.
Thanks Dave.
