How to randomly print a word in an iOS app? - ios

Question

I have been trying to create an app that randomly prints a new word after a certain amount of time, i.e five seconds.
import UIKit
class ViewController: UIViewController {
var myTimer : Timer!
var theValue = 0
#IBOutlet weak var textLabel: UILabel!
#IBOutlet weak var InspireLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib
}
override func viewDidDisappear(_ animated: Bool) {
self.myTimer.invalidate()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#objc func updateMyLabel() {
theValue += 1
self.textLabel.text = String(theValue)
}
func randomText() -> String {
if theValue > 5 {
let words = ["Place", "Cat", "House"]
return words.randomElement() ?? "" //Use default method to get random element from Array
}
return "string if theValue < 5 or equal to 5"
}
#IBAction func ResetButton(_ sender: Any) {
self.myTimer.invalidate()
theValue = 0
self.textLabel.text = String(theValue)
}
#IBAction func PauseButton(_ sender: Any) {
self.myTimer.invalidate()
}
#IBAction func PlayButton(_ sender: Any) {
self.myTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(updateMyLabel), userInfo: nil, repeats: true)
}
}
This is all the code I have right now. As you can probably tell I'm new too StackExchange and so please excuse any breach in etiquette.

Answer 1

it's giving an error because you forgot to add else part in your code.
func randomText() -> String {
if theValue > 5 {
let words = ["Place", "Cat", "House"]
return words.randomElement() ?? "" //Use default method to get random element from Array
}
return "string if theValue < 5 or equal to 5"
}
