我正在尝试使用图像将CollectionView添加到我的应用程序中。所以我在xib文件中设置了一个单元格并添加了一个imageview，现在给出了单元格标识符“Cell”，并将它的委托和数据源设置为文件的所有者。
我现在遇到的问题是，只要我使用CollectionView进入屏幕，应用程序就会崩溃。

请注意，在使用Objective C进行编码时，我是一个完整的菜鸟。我正在尝试研究它。

我所要做的就是改变
@interface CollectionViewController : UICollectionViewController
要
@interface CollectionViewController : UIViewController
现在没有错误，一切都按预期工作。

您需要将xib单元注册到视图控制器的 - （void）viewDidLoad上的UICollectionView。
[_tableView registerNib:[UINib nibWithNibName:@"nibName"
bundle:nil]
forCellReuseIdentifier:@"cellIdentifer"];
