I’ve created an app using the new iOS 5 Utility app template. Since the previous SDK, we now have to use storyboards for the GUI (which I do like using) but I am wondering how to prevent the “Segue” from flipping the view to the next view on the storyboard.
By default there is a button which when pressed flips to the “FlipsideViewController” and I would like to use this button as part of a login form but I need to stop the storyboard going to the Segue unless the credentials are correct. I have all my login code written but cannot prevent the page from flipping. The method I thought would do this actually prevents the user from going back by clicking the default “Done” button on the “FlipsideViewController”.
Can anyone help?
You have to connect the button to an IBAction instead of a segue. In the action, check if the credentials are correct, then call
performSegue:to perform it.You will have to connect the segue directly from the view controller to the next scene instead of from the button.
