Question

我希望有人可以帮我解决这个问题。我在视图中创建了一个自定义表视图，我从服务器下载数据并将其放入表中。现在我有一个自定义单元格，在自定义单元格内部有一个名为“跟踪”的标签。一切似乎都很好但是当我去加载我的应用程序时它会崩溃并给我以下错误：

2016-01-10 23：34：06.107 uDropOff [88265：2009009] ***终止应用由于未捕获的异常'NSUnknownKeyException'，原因：'[setValue：forUndefinedKey：]：这个类不是键符号编码 - 符合密钥tableView。'

我希望有人可以提供帮助，我会发布单元格和下面的视图的代码。
