当我将 IBOutlet 连接到 UITextField 时，我遇到了这个奇怪的错误。这真的很奇怪，因为它只发生在这个视图控制器中。我还有另外两个与这个几乎相同的视图控制器，它们运行良好。我的故事板中有一个表格视图控制器。它有 2 个分组部分，每个部分都有静态单元格。每个单元格中都有一个 UITextField。现在，如果我只运行它而不将文本字段连接到我的类，则视图加载正常。但是，当我连接它们时，一旦视图加载-应用程序因此错误而崩溃，每个文本字段都有一个： [UITextField stringByTrimmingCharactersInSet:]: unrecognized selector sent to instance
知道这可能是什么原因吗？我很困惑，因为我有其他具有相同内容的 tableview 控制器，但我从未收到此错误。
以下是一些屏幕截图，可帮助进一步解释我的情况：
