Answer 1

You make what I call "generic" segues that are not associated with an action/trigger. See my answer here: How to make and use generic segue

Make 2 of these segues, then in your IBAction method for your segmentedControl call performSegueWithIdentifier:. For example:

- (IBAction)segmentCtrlChanged:(id)sender {
 UISegmentedControl *seg = sender;
 if (seg.selectedSegmentIndex == 0) 
   [self performSegueWithIdentifier:@"segue1" sender:self];
 else if (seg.selectedSegmentIndex == 1) 
   [self performSegueWithIdentifier:@"segue2" sender:self];
}

Answer 2

You only need one segue in your storyboard. in you viewcontroller, add the

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

method, and use switch to decide which segment is being selected.

e.g.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    switch (self.segmentedButton.selectedSegmentIndex)
    {
          case 0:
          {
                UIView1 *view1 = (UIView1 *)segue.destinationViewController;
                // do other customization if needed
                break;
          }
          case 1:
          {
                UIView2 *view2 = (UIView2 *)segue.destinationViewController;
                // do other customization if needed
                break;
          }
          default:
               break;
    }
}
