问题：
I added a new nib file to my project, and tried to load it. 我向项目添加了一个新的nib文件，并尝试加载它。
However, when I click on the toolbar icon that is supposed to take me to the view that I created, I get an NSInternalInconsistencyException with the message: 但是，当我单击应该将我带到创建的视图的工具栏图标时，我收到一条NSInternalInconsistencyException消息：
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "..." nib but the view outlet was not set.' 由于未捕获的异常'NSInternalInconsistencyException'而终止应用程序，原因：'-[UIViewController _loadViewFromNibNamed：bundle：]加载了“ ...”笔尖，但未设置视图出口。
So I opened up my nib file, and I see for the view that there are no referencing outlets set. 因此，我打开了我的nib文件，并且看到没有设置参考插座的视图。 However, I try to click and drag the circle for "new referencing outlet" to File's Owner, but it won't let me...what do I need to do to get my view to display? 但是，我尝试单击并拖动“新引用出口”的圆圈到File's Owner，但这不会让我...我需要做些什么才能显示我的视图？
