如何在Swift中處理許多UIButton上的輕擊

Question

我正在嘗試在Swift中制作一個應用程序，該應用程序具有以一位整數作為標簽文本的標簽網格。 我想點擊一個標簽並使其具有整數增量。我從一個有關Tic Tac Toe應用程序的教程中了解到，我可以使用一個清除按鈕（1-36）覆蓋每個標簽，並使用水龍頭來增加標簽（1 -36）下方的文字編號。 到現在為止還挺好。 本教程使用switch語句來傳遞所點擊按鈕的標簽，並將案例硬編碼到Label引用中。 這對Tic Tac Toe很好，因為它只有3x3的網格，但是我的網格是6x6的，而且我懶於對所有36種情況進行硬編碼。 有沒有更聰明的方法來傳遞按鈕標簽並執行此操作？

我正在考慮將按鈕標簽文本整數存儲在數組中並對其進行讀取/寫入/然后從那里更新標簽。 這可能比我現在擁有的要好，但是我認為它不能解決我的switch語句問題。

任何意見，將不勝感激。

使用按鈕的label屬性代替多余的標簽。 看起來像這樣：

@IBOutlet var Button1: UIButton!  //Row one
@IBOutlet var Button2: UIButton!
@IBOutlet var Button3: UIButton!
@IBOutlet var Button4: UIButton!
@IBOutlet var Button5: UIButton!
@IBOutlet var Button6: UIButton!
....

@IBAction func increaseLabel(sender: UIButton) {
    var currentLabel = sender.titleLabel.text.toInt()!
    currentLabel = currentLabel + 1
    sender.setTitle("\(currentLabel)", forState: .Normal)
}

然后將所有按鈕連接到Interface Builder中的該操作。
