cell.hidden = YES; //or cell.alpha = 0.0;

但滚动后,单元格再次出现.我也尝试了以下内容：

UICollectionViewLayoutAttributes *layoutAttr = <get the layout attribute>//I'm succesfull here
layout.hidden = YES;
[cell applyLayoutAttributes:layoutAttr];

我认为这可能是因为我正在使用dequeReusable ..方法,因此该单元格正被重新使用,但是
我也试图隐藏collectionView：cellForItemAtIndexPath：方法中的单元格无济于事.在这里它似乎甚至没有工作.

为什么这不起作用？如何隐藏UICollectionViewCell？

编辑：包含collectionView的实现：cellForItemAtIndexPath ::

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *identifier = @"Cell";

    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
    cell.layer.cornerRadius  = 12.0f;
    cell.backgroundColor = [UIColor colorWithRed:0.830 green:0.899 blue:1.000 alpha:1.000];

    cell.selectedBackgroundView = [[UIView alloc]initWithFrame:cell.frame];
    cell.selectedBackgroundView.backgroundColor = [UIColor lightTextColor];;
    cell.layer.borderColor = [UIColor blackColor].CGColor;
    cell.layer.borderWidth = 2.0f;
    cell.hidden = YES;
    UILabel *lbl = (UILabel *)[cell viewWithTag:10];
    NSArray *interArray = numberArray[indexPath.section];
    [lbl setText:[interArray[indexPath.row] stringValue]];

    return cell;



}

这应该隐藏所有细胞吗？但不,不会发生.
