UICollectionElementKindCell带有标识符的视图不能出队

我有UICollectionView，但似乎我设置一切正确。 但是我得到的错误：

'could not dequeue a view of kind: UICollectionElementKindCell with identifier PeopleCellForList - must register a nib or a class for the identifier or connect a prototype cell in a storyboard' 

我的故事：

我的代码是：

 @interface PeopleCellForList : UICollectionViewCell @end @implementation PeopleCellForList @end #pragma mark - UICollectionView Datasource - (NSInteger)collectionView:(UICollectionView *)view numberOfItemsInSection:(NSInteger)section { return self.arrayPeople.count; } - (NSInteger)numberOfSectionsInCollectionView: (UICollectionView *)collectionView { return 1; } - (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath { UICollectionViewCell *cell = [cv dequeueReusableCellWithReuseIdentifier:@"PeopleCellForList " forIndexPath:indexPath]; return cell; } #pragma mark - UICollectionViewDelegate - (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath { } - (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath { } #pragma mark – UICollectionViewDelegateFlowLayout - (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath { CGFloat width = 106; CGFloat height = width; if (indexPath.row % 3 == 2) { width = 108; } return CGSizeMake(width, height); } - (UIEdgeInsets)collectionView: (UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section { return UIEdgeInsetsMake(0, 0, 0, 0); } 

我试图[self.collectionViewMain registerClass:[PeopleCellForList class] forCellWithReuseIdentifier:@"PeopleCellForList"]在viewDidLoad:在此期间，我试图删除，而不是从故事板中删除单元格），但没有帮助。

你在@"PeopleCellForList "有一个额外的空间
