Segue from screen with several buttons?

I am trying to write an app using UINavigationViewController. My first screen has several buttons on it, and on the click of each button, I want to segue to a UIViewController. I know that I can add a segue on each button, all pointed to the UIViewController that I want to go to, but I was wondering if it is possible to use only one segue that can be fired from each of the buttons.

If that is not possible, I was wondering if it was possible to open the second UIViewController from the first one, on button click, and provide a Back button like the UINavigationView provides. I did manage to get everything on this idea working, except for the back button. I mean I can put a standard button somewhere on the screen and go back, but I'd like the standard back button on the UINavigationView.

Phew! I'm not sure if that makes any sense.

I know that I could also use a tableview, but I'm trying to set this up with buttons.

Thanks

Edit: Thank you to everyone that answered. I now have this working. I would vote up the answers, but I don't have enough posts to do it. I appreciate the answers!

If you need to have separate action functions for each button, suggest that you segue from the main controller to the other controller and create a segue identifier (see xcode procedure below); then, use performSegueWithIdentifier from each of the button action functions. You can also take advantage of the prepareForSegue. To create the segue, control-drag from the left button in the controller in the storyboard to the controller you want to segue to and pick show.

Check the example code in swift that I did for a very similar problem in the SO reference

Linking View Controllers through button

You can embed the main controller in a navigation controller and that will give you the ability to navigate back. If you have multiple layers you can also use unwind segue.

Link each button to one single action (ex. buttonClick) in that ViewController and then perform the appropriate segue using pushViewController method on self.navigationController

-(IBAction)buttonClick:(id)sender {
if(sender.id == self.button1) {
    DestinationViewController *vc = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"VC_IDENTIFIER"];
    [self.navigationController pushViewController:vc animated:YES];
}

Or if you already have that 1 segue defined in storyboards you can use 

[self performSegueWithIdentifier:@"SegueIdentifier" sender:self];

And use that inside the buttonClick method. Using the 1st example, or the second one as long as the segue you setup in the storyboards is a push then you should already get the back button as that is the default behavior for pushing view controllers onto the navigation stack.
