iOS Swift application for easy bill splitting at the restaurant

Short description

This app is just a small but very handy tool for bill splitting in the restaurant. Input bill total, by how many persons to divide, how much you want to leave for tip and you will immediately see how much everyone need to pay.

How it looks like

Demonstration

Code, I used

1. import UIKit
3. class ViewController: UIViewController {
6. @IBOutlet weak var stepperDevide: UIStepper!
7. @IBOutlet weak var txtBillTotalField: UITextField!
8. @IBOutlet weak var txtEach: UILabel!
9. @IBOutlet weak var txtDevideCount: UILabel!
10. var total:Float = 0.0
11. @IBOutlet weak var txtTip: UILabel!
12. @IBOutlet weak var txtPercentForTip: UILabel!
13. @IBOutlet weak var sliderTip: UISlider!
15. override func viewDidLoad() {
16. super.viewDidLoad()
18. let tapGesture = UITapGestureRecognizer(target: self,action:#selector(hideKeyboard))
20. txtBillTotalField.keyboardType = UIKeyboardType.numbersAndPunctuation
21. view.addGestureRecognizer(tapGesture)
22. }
23. @objc func hideKeyboard() {
24. view.endEditing(true)
25. }
27. @IBAction func sliderListener(_ sender: Any) {
28. refreshLabels()
29. }
30. @IBAction func txtBillTotal(_ sender: Any) {
31. refreshLabels()
32. }
34. @IBAction func stepperListener(_ sender: Any) {
35. refreshLabels()
36. }
38. func refreshLabels(){
39. total = (txtBillTotalField.text!.replacingOccurrences(of: “,”, with: “.”) as NSString).floatValue
41. let tipTax = total * sliderTip.value.rounded() * 0.01
42. let devide = Float(stepperDevide.value)
43. let each = (total + tipTax) / devide
45. txtEach.text = (NSString(format: “%.2f€”, each) as String).replacingOccurrences(of: “.”, with: “,”)
47. txtDevideCount.text = NSString(format: “%.0f”, devide) as String
49. txtTip.text = (NSString(format: “%.2f€”, tipTax) as String).replacingOccurrences(of: “.”, with: “,”)
51. txtPercentForTip.text = NSString(format: “%.0f”, sliderTip.value) as String + “% for tip”
52. }
54. }
