- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
    return 1;
}

- (NSInteger)collectionView:(UICollectionView *)view numberOfItemsInSection:(NSInteger)section
{
    return 100;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"Cell";
    CollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
    if (cell)
    {
//        cell.backgroundColor=[UIColor blueColor]; // it's work
        CollectionView.backgroundColor = [UIColor whiteColor];
//        UIImageView *iser = [[UIImageView alloc] init];  // it's not working
//        iser.image = [UIImage imageNamed:@"image.png"];  // it's not working
//        [cell.CellImageView addSubview:iser];  // it's not working
        cell.CellImageView.image = [UIImage imageNamed:@"image.png"];  // it's not working
    }
    return cell;
}

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    return CGSizeMake(106, 107);
}

-(CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section
{
    return 1;
}

-(CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout minimumLineSpacingForSectionAtIndex:(NSInteger)section
{
    return 1;
}

这是我的代码我试图在所有集合视图中显示一个图像（至少）但它没有工作任何人告诉我我做错了什么

评论4行是替代行我已经尝试了4条评论行，这也是

cell.CellImagView.image = [CollectionViewImageArray objectAtIndex:indexPath.row];
cell.backgroundColor = [UIColor clearColor];

我首先想到的是我需要在collectionviewCell中至少显示一个图像，然后移动到数组

如果我评论单元格颜色collectionviewcell什么都不显示

UICollectionView单元imageview不显示图像，但它显示背景颜色xcode
