how to use label instead of button in prepareforsegue in swift

In my app you type an integer in a textField in viewcontroller1. If the integer is greater than 100 a label will pop up on screen and when you click on it, you will go to viewcontroller2. The same repeats from viewcontroller2 and viewcontroller3.

However I want the integer in viewcontroller1 to be displayed in another label in viewcontroller3, which I then learned to use prepareforsegue to be able to do so.

Now my problem is, my prepareforsegue only works if I use a button, its seems like I can't connect my label you click to go to the viewcontroller as a segue connection? (is this possible? If not, what can I do to keep my label but work as my button is now, so my prepareforsegue is working correctly.

A label is not a UIControl element so it doesn't recognize touch events natively. You need to attach a tapGestureRecognizer to the label (make sure user interaction is enabled on the label). Then you can attach the gesture recognizer to your @IBAction method or trigger the segue. If using IB, the referencing outlet connection from the gesture recognizer should be tied to the label.

first give the segue an identifier in storyboard and on label click or tap method use performSegueWithIdentifier("identifier", sender: self). This way the prepareForSegue gets called even on tapping label (Note: userInteraction should be enabled on label) In your code replace self.presentViewController(vc as! UIViewController, animated: true, completion: nil) with self.performSegueWithIdentifier("identifier", sender: self)
