Ios 无法在NSObject Xcode中使用UIView

这是我的桌面视图

如您所见，此错误：未设置UITableView数据源表示未设置表视图数据源。您必须将表视图与interface builder中的数据源连接。

缺少UIKit导入？它显示了另一个错误，如-[NSBubbleTblView\u createPreparedCellForGlobalRow:WithindXPath:willDisplay:]，/SourceCache/UIKit\u Sim/UIKit-3318.16.14/UITableView.m:9269 2015-07-27 16:53:23.807 Hansel[6740:143046]***由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“未设置UITableView数据源”我已使用数据源和表视图单元格创建了自定义表视图，因此当我运行项目时，它会显示上述错误。这是另一个错误。这是运行时的错误。您显示的代码中没有“UITableView”。我们猜不出是怎么回事。我知道，但在-[NSBubbleTblView]中运行程序***断言失败时，它会出现另一个异常，createPreparedCellForGlobalRow:withIndexPath:willDisplay:，/SourceCache
