Ios UITAP手势与viewDidLoad/General Tic Tac Toe中的功能通信

我一直在尝试使用UILabels和UITapPictures的条件来编程Tic Tac Toe。我觉得我已经理解了大部分逻辑，但我很难理解点击TapGestureRecognitor如何触发viewDidLoad中的函数，因为uilabel文本必须更改

起初，我尝试了viewDidLoad之外的@iActions，但没有成功，然后我尝试了编程连接，但需要#选择器（MyClass.function），但我无法在现有的viewDidLoad函数中实现点击手势识别器的功能

这是我所有的代码

您不应创建

UIgestureRecognitizer

的实例。仅创建特定类型手势的实例，如

UITapgestureRecognitizer

。并了解有关数组和插座集合的知识。有9个标签插座很笨重。为什么要使用可点击标签？为什么不使用

ui按钮

？最重要的是，不要以这种方式使用嵌套函数。虽然斯威夫特支持这一点，但至少在我的经验中，这很少被使用。您应该将点击处理程序移到

viewDidLoad

之外。您说过

iAction

s对您不起作用-他们应该这样做。这种方法出了什么问题？您永远不应该创建
