objective c - Conditionally following a segue

Question

In my app I have a login screen. When connecting a segue from the login button to the next (table) view controller however, you are always able to proceed, no matter what you type in as login information. How can I check the login information and then decide whether to perform the segue or not, so how to perform the segue conditionally?

Is it possible to achieve this while working with a segue? I know it can be done programmatically, but then I need another navigation controller cause I need a navigation bar..

Answer 1

You can wire up your login button or whatever to some IBAction code, decide if the login should proceed and then (if it should) you can use performSegueWithIdentifier: to transition to the new view.

I just wrote another post about using this method, here.
