How to loop a Slider value for height? - ios

Question

I successfully created a slider for user height in storyboard and the corresponding code to assign a value in the slider to each level of height but as you can see below, I had to manually copy & paste each new height variable to get it to work. I was curious how an expert would simplify this code? thanks!
*note - I removed the code for height 5'2 to 6'4 to not take up so much space.
'''
#IBOutlet weak var yourHeightEquals: UILabel!
#IBOutlet weak var heightSliderOutlet: UISlider!
#IBAction func heightSliderAction(_ sender: UISlider) {
heightSliderOutlet.value = roundf(heightSliderOutlet.value)
let yourHeightText: String = "Your Height: "
if heightSliderOutlet.value == 0 {
let yourHeightString = "Choose Your Height"
yourHeightEquals.text = yourHeightString
}
else if heightSliderOutlet.value == 1 {
let yourHeightString = "<5'0"
yourHeightEquals.text = yourHeightText + yourHeightString
}
else if heightSliderOutlet.value == 2 {
let yourHeightString = "5'0"
yourHeightEquals.text = yourHeightText + yourHeightString
}
else if heightSliderOutlet.value == 3 {
let yourHeightString = "5'1"
yourHeightEquals.text = yourHeightText + yourHeightString
}
.......
else if heightSliderOutlet.value == 19 {
let yourHeightString = "6'5"
yourHeightEquals.text = yourHeightText + yourHeightString
}
else if heightSliderOutlet.value == 20 {
let yourHeightString = ">6'5"
yourHeightEquals.text = yourHeightText + yourHeightString
}
}

Answer 1

You can use a switch statement like this.
#IBOutlet weak var heightSliderOutlet: UISlider!
#IBOutlet weak var yourHeightEquals: UILabel!
#IBAction func heightSliderAction(_ sender: UISlider) {
let value = roundf(heightSliderOutlet.value)
switch value {
case 0:
yourHeightEquals.text = "Choose Your Height"
case 1:
yourHeightEquals.text = "Your Height : <5'0"
case 2...19:
let height = 5.0 + ((value - 2) * 0.1)
yourHeightEquals.text = "Your Height : \(height)"
default:
yourHeightEquals.text = "Your Height: >6'5"
}
}

Update - the switch code above only worked for a metric system - I had to modify it a bit for feet & inches, still much cleaner than my original code!
#IBOutlet weak var yourHeightEquals: UILabel!
#IBOutlet weak var heightSliderOutlet: UISlider!
#IBAction func heightSliderAction(_ sender: UISlider) {
let value = roundf(heightSliderOutlet.value)
switch value {
case 0:
yourHeightEquals.text = "Choose Your Height"
case 1:
yourHeightEquals.text = "Your Height: <5'0"
case 2...11:
let height = 5.0 + ((value - 2) * 0.1)
let heightstring = String(height)
let heightfoot = heightstring.dropLast(2)
let heightinch = heightstring.dropFirst(2)
let heightfootinch = heightfoot + "'" + heightinch
yourHeightEquals.text = "Your Height: \(heightfootinch)"
case 12:
yourHeightEquals.text = "Your Height: 5'10"
case 13:
yourHeightEquals.text = "Your Height: 5'11"
case 14...19:
let height = 6.0 + ((value - 14) * 0.1)
let heightstring = String(height)
let heightfoot = heightstring.dropLast(2)
let heightinch = heightstring.dropFirst(2)
let heightfootinch = heightfoot + "'" + heightinch
yourHeightEquals.text = "Your Height: \(heightfootinch)"
default:
yourHeightEquals.text = "Your Height: >6'5"
}
}
