4,144 PointsStructs or Classes - Building a Simple iPhone App with Swift
When Pasan creates the iPhone app Fun Facts it appears to me (Unless I am missing something) that the app can only show two facts total out of all the available facts in the array. Is this the case (And he is doing it to keep it simple) or am I doing something wrong with my code? - For example Using factProvider.facts[1] is only ever going to give the second fact in the array, so it will never really change.
class ViewController: UIViewController { @IBOutlet weak var factsGoHere: UILabel!
let factProvider = FactProvider()
override func viewDidLoad() {
super.viewDidLoad()
factsGoHere.text = factProvider.facts[0]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func newFact(_ sender: Any) {
factsGoHere.text = factProvider.facts[1]
}
}
