我真的很难修复这个NSUnkownKeyException我现在正在UITableView中创建一个单元格。这是导致错误的代码行：
let cell = tableView.dequeueReusableCellWithIdentifier("eventCell", forIndexPath: indexPath) as! EventTableViewCell
实际错误：

非常感谢您的帮助，非常感谢！

dequeueReusableCellWithIdentifier正在尝试从EventTableViewCell实例化.xib听起来该文件包含无效绑定，该绑定试图设置view属性（不存在）EventTableViewCell。在Xcode中查看你的xib，你可能会收到有关无效插座绑定的警告。

你应该在nib / storyboard中选择tableview单元格并检查实用程序面板中的Outlets。如果有任何损坏的插座进入单元格，Xcode会将bang标记放到连接节点。要查找xib / storyboard，你应该使用EventTableViewCell搜索xcode
