应用程序在xib编辑后崩溃

标签: iphone xcode uinavigationbar xib

我有一个导航控制器应用程序。我用Xib文件创建了一个RootViewController类。在那个xib文件中,我有表视图,仅此而已。我以程序方式创建的工具栏上的工具栏和按钮。表视图有datasourse和委托文件所有者。

我删除了这个xib文件,并创建了一个具有以前名称的新文件。创建它像viewBased xib文件,然后我下拉到它的工作站上的表视图,工具栏,两个按钮。添加插座。保存了一切。清除所有目标。建立所有。并运行。应用程序在启动时崩溃!谁知道问题出在哪里?感谢名单!

* 由于未捕获的异常而终止应用   'NSInternalInconsistencyException',   原因:' - [UIViewController   _loadViewFromNibNamed:bundle:]加载了“RootViewController”nib但是   查看插座未设置。'

您的视图控制器丢失了视图插座的连接,您需要在IB中恢复它(与所有插座一样)
