Generate a random number between 0 and 100
This is my current code:
let min = UInt32(0)
let max = UInt32(100)
@IBOutlet weak var percent: UILabel!
@IBAction func finalButton(sender: AnyObject) {
func randNum (min: Int , max: Int) -> Int {
return min + Int(arc4random_uniform(UInt32(max - min + 1)))
}
percent.text = "\(randNum)+'%'"
}
When I run this it works fine until the button is clicked then I get a signal error even though all my code is connected when I look in the connection inspector. Is there a mistake in this code?

I think you are looking for something like this:
let min = 0
let max = 100
@IBOutlet weak var percent: UILabel!
func randNum (min: Int , max: Int) -> Int {
return min + Int(arc4random_uniform(UInt32(max - min + 1)))
}
@IBAction func finalButton(sender: UIButton) {
let randomNumber = randNum(min, max: max)
percent.text = "\(randomNumber)" + "%"
}
The function randNum
you are using is looking for the types Int
you need to pass into it. You are not passing any values to the function. Also, you have a function randNum
inside your function UIButton
. Is there a specific reason for this?
