Question

I have created several scenes within a storyboard file in my Xcode project, and the first scene that is loaded is a user login in screen. When a user logs in the UIButton “Login” takes the user to the welcome screen. I setup that in storyboard using a modal segue. I want a user with the name “admin” to be taken a welcome admin screen. I’m pretty sure it’s only possible to have one segue associated with one object, i.e. UIButton in storyboard, so I am stumped as to how I can accomplish the login to take the admin to the admin welcome screen, and take all other users to the user welcome screen. I really don’t want to create two separate login buttons, so that’s not an option.

I came across some stackoverflow posts with similar questions but all the answers seemed a little convoluted. Keep in mind I am new to Xcode, so if you paste code in your answer please specify which file the code should go in (that would help me out A LOT). I’ll post a picture of what my storyboard looks like so far to help demonstrate a visual diagram of what I am talking about.

Answer 1

If I understood your question correctly, here are the steps you need to take to make it work:

1. From the WelcomeViewController – where you have the username / password login button, control+drag from the UIViewController to the WelcomeScreen, and choose Modal from the pop up menu (By drag from UIViewController I mean, select the UIViewController in storyboard, there is a round shape icon on the bottom, from that to the destination view controller). Name the segue identifier as “UserSegue”

2. Repeat step 1, but instead control+drag it to Admin screen. Name the segue identifier as “AdminSegue”

3. You need now to subclass WelcomeViewController,

4. Implement -(IBAction)login:(id)sender

   - (IBAction)login:(id)sender {
   
       // assuming you have hooked up the user name text field
   
       if ([self.usernameTextField.text isEqualToString:@"admin"]) {
           [self performSegueWithIdentifier:@"AdminSegue" sender:sender];
       }
       else {
           [self performSegueWithIdentifier:@"UserSegue" sender:sender];
       }
   }
   

5. In storyboard, hook up the login button to the method in step 4.
