IBOutlet中与swift3.0

Question

arc4random我有代码

class ViewController: UIViewController { 

var detailText: String = "Chance of win is 50%" 

@IBOutlet weak var winChance: UILabel! 

func someMethod() -> Void { 
    print("Method called!") 
} 

override func viewDidLoad() { 
    super.viewDidLoad() 
self.winChance.text = self.detailText 
} } 

我怎样才能使这个50％arc4random？ 如果我用“（VAR）”的东西却是不由你想要的标签文字是我 日Thnx

试试这个

class ViewController: UIViewController { 

    @IBOutlet weak var winChance: UILabel! 

    func someMethod() -> Void { 
     print("Method called!") 
    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     let randomNumber = Int(arc4random_uniform(100)) 
     self.winChance.text = "Chance of win is \(randomNumber)%" 
    }  
}
