swift 整数値 Int() と 配列 Array() の抽出

Last updated at Posted at 2021-11-24

Intは整数値を定義するのに用い、Arrayは配列を組織する。

class ViewController: UIViewController {
var c = Int()
var elem = NSArray()
  override func viewDidLoad(){
    elem = [ 
      “Name1”, “name2”, “name3”, “name4”
    ]
    var btn1 = UIButton()
    btn1.addTarget(self, action: #selector(button1(button1:)), for: .touchUpInside)
  }
  @objc func button1(button1: UIButton){
    C += 1
    Object()
  }    
  Object(){
   if(c <= elem.count - 1){
      let name = elem[c]
    } else {
      let name = elem[0]
    }
    let label = UILabel()
    label.text = String(name)
  }
}

上の文字列は、ボタンを押すたび、に配列に置かれた、名前が変わり、ラベルに表示されることを記している。
