如何处理Swift中许多UIButton的点击

标签： ios swift uibutton

我正在尝试在Swift中创建一个应用程序，它有一个带有单个数字整数的标签网格作为标签文本。我想点击一个标签并获得整数增量。我从一个关于Tic Tac Toe app的教程中学到了我可以用一个清除按钮（1-36）覆盖每个标签并使用水龙头增加标签（1 -36）其下的文字编号。到现在为止还挺好。本教程使用switch语句传递轻敲按钮的标记，并将案例硬编码到Label引用。这对Tic Tac Toe来说很好，因为它只是一个3x3的网格，但我的网格是6x6而且我懒得硬编码所有36个案例。是否有更智能的方法来传递按钮标签并执行此操作？

我正在考虑将按钮标签文本整数存储在数组中并读取/写入/然后从那里更新标签。这可能比我现在的要好，但我认为它不能解决我的switch语句问题。

任何建议都将受到赞赏。

使用按钮的label属性而不是额外的标签。这看起来像这样：

@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)
}

然后在Interface Builder中将所有按钮连接到该操作。
