iOS UICollectionView show strange when cell has background colro

[mikezang]

I just create a UICollectionView, but when I set cell color, I got a strange result, can you tell me why?

- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath;
{
    static NSString *kCellID = @"Cell";
    WordCell *cell = [cv dequeueReusableCellWithReuseIdentifier:kCellID forIndexPath:indexPath];
    
    cell.label.text = [NSString stringWithFormat:@"%i%i", indexPath.section, indexPath.row];

   switch (indexPath.row) {
        case 0:
        case 1:
        case 4:
        case 5:
            cell.backgroundColor = [UIColor greenColor];
            break;
            
        case 2:
        case 3:
        case 6:
            cell.backgroundColor = [UIColor redColor];
            break;

        default:
            break;
    }
    
    return cell;
}

What's the issue here exactly? The fuzzy text?

If so, try setting cell.label.backgroundColor also.

The line of red color is not on the same position with line of black cell, can you view?

Well, I can see that the whole table is moved upwards by 1-2 pixels. I presumed that's just because of the way you have taken the screenshot? I can't see anything in the code you have posted that would cause the position of the UICollectionView to change.
