Swift one button 3 messages - ios

Question

I am new to Swift and I am coding on Xcode. I am trying to do like a "Hello, World!" in Swift by having an app that is just one screen, one button, and one display label.
My objective is to have three different messages appear with the click of the button. To clarify, each time I click the button it would cycle through the messages.
I tried solving it with a switch, here is my (unfinished attempt)
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var textBox: UILabel!
var userTapped = false
#IBAction func tappedMe(_ sender: UIButton) {
let me =
if userTapped {
switch me {
case me : textBox.text = "Hello, World!"
case me : textBox.text = "Hello, Human!"
case me : textBox.text = "OK scram."
default : break
}
userTapped = true
}
}
}
I'm not sure what I can make me equal to, or if my solution is even a good one.

Answer 1

class ViewController: UIViewController {
#IBOutlet weak var textBox: UILabel!
let strings = ["Hello, World!", "Hello, Human!", "OK scram."]
var tapCount = 0
#IBAction func tappedMe(_ sender: UIButton) {
textBox.text = strings[tapCount]
tapCount = (tapCount + 1) % strings.count
}
}

Answer 2

You could do something like this it would accomplish your goal if I understand it correctly:
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var textBox: UILabel!
// Integer to track number of times button has been tapped
var tapCount = 0
// Max total of text variations, for this case 2 (you have three different values, but always start with zero)
let max = 2
#IBAction func tappedMe(_ sender: UIButton) {
// Try different conditions for value of tapCount
switch tapCount {
case 0:
textBox.text = "Hello, World!"
case 1:
textBox.text = "Hello, Human!"
case 2:
textBox.text = "OK scram."
default : break
}
// If this is the max number of times you want to display changing text, reset tapCount to zero, otherwise increment tapCount.
if tapCount < max {
tapCount += 1
} else {
tapCount = 0
}
}
}
