我刚开始参加ios应用程序开发的在线课程，这是我在SO上的第一篇文章，所以请耐心等待。
进一步进行秒表练习，我设法将圈数记录到一个阵列中，后者填充主故事板上的 UITableView 。
一切都很好，除了一件事，当我开始滚动桌子时，秒表因某些我不知道的原因而停止，我希望你的答案可以被初学者理解。
我正在使用 XCode 7 。感谢。
正如您可能看到的，代码看起来很难看，正如我所说，这些是我编写代码的第一行，所以我认为如果我发布它会更好。
总结一下，主故事板包含两个计数器的两个标签，主计数器（计时器）一直继续，直到按下复位按钮但是lapTimer设置为零，其值保存到lapArr表，之后计数器再次开始。这是所有代码：

var timer = NSTimer()
var lapTimer = NSTimer()
var time = 0
var sec = 0
var min = 0
var lapTime = 0
var lapSec = 0
var lapMin = 0
var lap = ""
var lapArr = [""]

} else {

}
