我一直收到NSInternalInconsistencyException错误，但我正在注册一个自定义单元格。我正在尝试向UICollectionViewController添加UIPageViewController。我错过了什么？看来UIPageViewController正在创建我的类的一个新实例，当我打印出传递给cellForItemAt IndexPath的对象时，内存地址是两个不同的内存地址，如果它是相同的class，我假设它将是相同的内存地址。

在UIPageViewController的父级中我只是添加了控制器。

self.addChildViewController(self.venueProjector)
self.view.addSubview(self.venueProjector.view)
