I have 6-8 instances where I am receiving the error for not having the member tipCalc. I attempted to make an empty variable, but that only made things worse.
import UIKit
class ViewController: UIViewController {
#IBOutlet var totalTextField : UITextField!
#IBOutlet var servQualitySlider : UISlider!
#IBOutlet var foodQualitySlider : UISlider!
#IBOutlet var servQualityLabel : UILabel!
#IBOutlet var foodQualityLabel : UILabel!
#IBOutlet var resultsTextView : UITextView!
#IBAction func calculateTapped(sender : AnyObject){
tipCalc.total = Double((totalTextField.text as NSString).doubleValue)
let possibleTips = tipCalc.returnPossibleTips()
var results = ""
for (tipPct, tipValue) in possibleTips{
results += "\(tipPct)%: \(tipValue)\n"
}
resultsTextView.text = results
}
#IBAction func servQualityChanged(sender : AnyObject){
tipCalc.servQuality = Double(servQualitySlider.value)/100.0
refreshUI()
}
#IBAction func foodQualityChanged(sender : AnyObject){
tipCalc.foodQuality = Double(foodQualitySlider.value)/100.0
refreshUI()
}
#IBAction func viewTapped(sender : AnyObject){
totalTextField.resignFirstResponder()
}
let tipCalc = TipCalculatorModel(total: 33.25, foodQuality: 0.06, servQuality: 0.06)
func refreshUI(){
totalTextField.text = String(format: "%0.2f", tipCalc.total)
foodQualitySlider.value = Float(tipCalc.foodQuality) * 100.0
servQualitySlider.value = Float(tipCalc.servQuality) * 100.0
foodQualityLabel.text = "Food Quality 1-10 (\(Int(foodQualitySlider.value))%)"
servQualityLabel.text = "Service Quality 1-10 (\(Int(servQualitySlider.value))%)"
resultsTextView.text = ""
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
refreshUI()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
I am getting a bunch of the same error messages saying "ViewController does not have a member named tipCalc"
I am also receiving the error "Use of unresolved identifier TipCalculatorModel"
How do I fix this issue? Thank you!

Answer 1

import Foundation
class TipCalculatorModel{
var total: Double
var foodQuality: Double
var servQuality: Double
var subtotal: Double{
get{
return total / (foodQuality + servQuality + 1)
}
}
init(total: Double, foodQuality: Double, servQuality: Double){
self.total = total
self.foodQuality = foodQuality
self.servQuality = servQuality
}
func calcTipWithTipPct(foodQuality: Double, servQuality: Double)->Double{
return subtotal * (foodQuality + servQuality)
}
func returnPossibleTips()->[Int:Double]{
let possibleTipsInferred = [0.15, 0.18, 0.20]
let possibleTipsExplicit:[Double] = [0.15, 0.18, 0.20]
var retval = [Int:Double]()
for possibleTip in possibleTipsInferred{
let intPct = Int(possibleTip*100)
retval[intPct] = calcTipWithTipPct(foodQuality, servQuality: servQuality)
}
return retval
}
}
I solved the issue by just pasting in the other module. Not a pretty fix. But it works. Thank you.
