我有UICollectionView，但似乎我设置了一切正确 . 但我得到错误：
'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);
}
我在 viewDidLoad: 尝试了 [self.collectionViewMain registerClass:[PeopleCellForList class] forCellWithReuseIdentifier:@"PeopleCellForList"] （在此期间我尝试删除而不是从故事板中删除单元格），但这没有帮助 .
