Showing segue after button action

Question

I have an iOS Swift app with 8 buttons that call the same segue, but this is very repetitive. How can I refactor so it uses the same function prepare?

@IBAction func backButtonPressed(_ sender: Any) {
 self.vcWithType = VCtype.back.rawValue
 self.postion = "back"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
@IBAction func mountButtonPressed(_ sender: Any) {
 self.vcWithType = VCtype.mount.rawValue
 self.postion = "mount"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
@IBAction func kneeRideButtonPressed(_ sender: Any) {
 self.vcWithType = VCtype.knee.rawValue
 self.postion = "knee"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
@IBAction func sideKbuttonPressed(_ sender: Any) {
 self.vcWithType = VCtype.sideK.rawValue
 self.postion = "side"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
@IBAction func northSouthBpressed(_ sender: Any) {
 self.vcWithType = VCtype.northSouth.rawValue
 self.postion = "north"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
@IBAction func guardBpressed(_ sender: Any) {
 self.vcWithType = VCtype.guarda.rawValue
 self.postion = "guard"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
@IBAction func halfGuardBpressed(_ sender: Any) {
 self.vcWithType = VCtype.halfGuard.rawValue
 self.postion = "half"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
@IBAction func turtleBpressed(_ sender: Any) {
 self.vcWithType = VCtype.turtle.rawValue
 self.postion = "turtle"
 self.performSegue(withIdentifier: "showCategory", sender: sender)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
 if (segue.identifier == "showCategory") {
 if let vc: CategoryViewController = segue.destination as? CategoryViewController {
 vc.vcWithType = self.vcWithType
 vc.chaza = self.postion
 }
 }
}

• Rahul Patel: Create enum of your position, and instead of calling independent method on every button, call only one method.

I think easiest way is using tags. You can connect more then one button to one IBAction func. Just Make sure sender is UIButton.

After that change buttons tag property.

After changing tags. We just need to use switch-case

@IBAction func ButtonAction(_ sender: UIButton) {
 switch sender.tag {
 case 0:
 print("Button 1 Clicked")
 case 1:
 print("Button 2 Clicked")
 default: break
 }
}

• Adrian: You can set the tag programmatically if you don't want to dig around in Interface Builder setting them. To reduce the chance of typos, you might want to use an enum to store your tags and reference the enum when setting the button tags.
