Math 多答案数学游戏小测验

我有一个数学问答游戏，我希望用户能够触摸按钮，现在它将只工作，如果我有一个按钮设置为正确的答案。是否有可能使其成为一个按钮组合，如答案为53，则用户可以触摸5按钮和3按钮

诀窍在于程序如何知道用户何时通过按键输入完数字

一种方法可能是将答案设置为可编辑文本字段（UITextField），并将焦点设置为该字段，并将键盘设置为数字类型键盘（通过UITextField实现的

uitextraits

协议），以便用户可以键入数字值

如果您不想使用iOS键盘，只想使用自己的自定义按钮，那么您可以使用自己的按钮，并让每个按钮的操作将适当的数字附加到答案字符串，您可以在UILabel中显示该字符串，并在他们按下按钮时进行更新。您希望有一个后退/删除按钮，以便他们可以删除数字和同时更新那里的字符串。使用此模型，您可能会有一个“确定”按钮或“完成”按钮，用于指示他们已完成，当前字符串是他们的答案。该按钮将在该点上获取答案字符串中的字符串，并检查其是否正确/不正确

希望这足以让您继续！您是否考虑过使用数组和循环，而不是十次编写相同的内容？
