swiftでランダム変数

Posted at

ほんと何番煎じかわからないけど、、
ランダム変数生成して判定するってのを書いてみました。

class SecondViewController: UIViewController {
    @IBOutlet var message : UILabel
    @IBAction func actionButton(sender : AnyObject) {
        let randInt = arc4random_uniform(10);
        if(randInt <= 5) {
            message.text = "hoge"
        } else {
            message.text = "moge"
        }
    }   
}

画面上にラベルとボタンを設置して
ラベル -> @IBOutlet var message : UILabel
ボタン -> @IBAction func actionButton
と、つなげる。

ボタンを押すと、0~10までのランダム変数がarc4random_uniform(10)で生成されて、
生成された変数の値が5以下であればhogeそうでなければmogeがラベルに表示される。

そんだけ。
ほとんどswift感ないけど、、、。
