错误无法使类型UICollectionElementKindCell的视图出列 [英] Error could not dequeue a view of kind UICollectionElementKindCell

问题描述

首先尝试使用集合视图并遇到此错误：

Taking first plunge with collection views and am running into this error:

由于未捕获的异常'NSInternalInconsistencyException'而终止应用，原因： '无法使类型的视图出列：具有标识符Cell的UICollectionElementKindCell - 必须为标识符注册nib或类或在故事板中连接原型单元'

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'could not dequeue a view of kind: UICollectionElementKindCell with identifier Cell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'

代码非常简单，如下所示。我不能为我的生活弄清楚我错过了什么。

The code is very simple, as shown below. I can't for the life of me figure out what it is that I'm missing.

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
cell.backgroundColor = [UIColor whiteColor]; 
return cell;
}

集合视图控制器是使用nib和委托&创建的。数据源都设置为文件的所有者。

The collection view controller was created using a nib and the delegates & datasources are both set to file's owner.

View Controller的头文件也非常基本。

View Controller's header file is also really basic.

@interface NewMobialViewController_3 : UICollectionViewController <UICollectionViewDataSource, UICollectionViewDelegateFlowLayout>
@end

推荐答案

来自 UICollectionView文档用于出列方法：

重要：您必须使用registerClass注册类或nib文件：forCellWithReuseIdentifier：或registerNib：forCellWithReuseIdentifier：调用此方法之前的方法。

Important: You must register a class or nib file using the registerClass:forCellWithReuseIdentifier: or registerNib:forCellWithReuseIdentifier: method before calling this method.
