Swift 3-线程1：信号SIGABRT未识别选择器发送到实例

能帮我解决这个问题吗？我花了几个小时试图解决这个问题，但到目前为止没有任何效果。每次我点击一个按钮，它立即导致错误线程1：信号SIGABRT

这是代码（注意：仍在进行中）：

这就是错误：

你能检查一下@IBAction func ButtonPressed（）与情节提要之间的连接吗？您可以从情节提要上的“连接检查器”中进行检查。

您是否使用Interface builder设置了

iAction

方法？从情节提要中删除操作并删除代码，然后读取按钮操作

@iAction func ButtonPressed（{sender:Any）{}

我将情节提要上的按钮拖到视图控制器mukesh中，我被你的意思弄糊涂了这是我进入连接检查器时屏幕上的内容（我还是一个初学者），我想问题可能是你没有将一个按钮连接到iAction。你能再检查一下吗？我怎么检查？我只将一个按钮连接到iAction，是否有方法连接所有按钮？如果要连接所有按钮，请执行与第一个连接按钮相同的操作。但这就是你想要的吗？（将所有按钮连接到一个iAction？）我希望能够检查是否单击了按钮x（其中所有按钮变量都存储为数组），如果单击了按钮x，则标签x将打印“x”
