UICollectionView adds top margin

Question

I want to put a UICollectionView control that shows thumbs horizontally (only a single line of thumbs). For some reason the UICollectionView push the thumbs 44 pixels down,

Answer 1

Maybe you can try to force this value at 0 using the Delegate flow layout of collection view :

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
    return UIEdgeInsetsMake(PADDING_TOP, PADDING_LEFT, PADDING_BOTTOM, PADDING_RIGHT);
}

Modify the value of your padding.
