Hiding UICollectionViewCell

Question

I'm trying to hide a UICollectionViewCell in a collection view. Although I'm successful when I do

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

but after a scroll the cell appears again. I've also tried the following:

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

I thought this might be because I'm using the dequeReusable.. method and hence the cell is being re used, but I have also tried to hide the cell in the collectionView:cellForItemAtIndexPath: method to no avail. Here it doesn't even seem to work.

Why is this not working? How can i hide a UICollectionViewCell?

EDIT: Included the implementation of collectionView: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;



}

This should hide all the cells right? But nope, it doesn't happen.

Since hiding the cell itself doesn't seem to work, you can either add a subview to the cell with the same color as the collection view's background color, or you can hide the cell's content view, which does work:

cell.contentView.hidden = YES;
cell.backgroundColor = self.collectionView.backgroundColor;

That second line is only necessary if you have set a background color for your cell.
