swift - 请告诉我如何写短代码

我是编程新手。
如下所示，我在UIView上有很多按钮。
在这种情况下，什么样的方法可以用短代码来表示？

class ViewController: UIViewController {
   @IBOutlet weak var buttonA: UIButton!
   @IBOutlet weak var buttonB: UIButton!
   @IBOutlet weak var buttonC: UIButton!
   @IBOutlet weak var buttonD: UIButton!
   @IBOutlet weak var buttonE: UIButton!
   @IBOutlet weak var buttonF: UIButton!
   @IBOutlet weak var buttonG: UIButton!
   @IBOutlet weak var buttonH: UIButton!
   @IBOutlet weak var buttonI: UIButton!
   @IBOutlet weak var buttonJ: UIButton!
   @IBOutlet weak var alphaView: UIView!

   override func viewDidLoad() {
      super.viewDidLoad()
      self.view.insertSubview(self.buttonA, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonB, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonC, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonD, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonE, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonF, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonG, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonH, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonI, aboveSubview: self.alphaView)
      self.view.insertSubview(self.buttonJ, aboveSubview: self.alphaView)
   }
}

最佳答案

创建一个outlet集合并将所有按钮连接到它。然后像这样迭代。

@IBOutlet var buttons: [UIButton]!{
    didSet{
        for button in self.buttons{
            self.view.insertSubview(button, aboveSubview: self.alphaView)
        }
    }
}
