Use this method at the point from where you want to segue to a new Controller.

[self performSegueWithIdentifier:@"yourSegueIdentifierName" sender:nil];

This method will automatically trigger the prepareForSegue method as soon as the above statement is encountered and as mentioned in your prepareForSegue method, you are checking the segue identifier names using if..else so that should do it.

Follow these steps :

  1. Use the didSelectRowAtIndexPath delegate method to check which row in the tableView was clicked. This is to know which segue identifier are we going to use for the particular row. Now you have your selectedRow index. So we go to next step.

  2. After knowing which row is being clicked, use this function for redirecting to the appropriate controller with the segue Identifer from your source Controller.

    [self performSegueWithIdentifier:@"yourSegueIdentifierName" sender:nil];

  3. As soon as your performSegueWithIdentifier is called, the prepareForSegue will be called immediately after it. And in that, as you have done right now, you can check the segue Identifier and use your own logic in that if...else code.
