I have a collection view, is working fine, and I have adjusted the separation for the X padding,

and it works fine, but for the Y padding between cells, doesn't seem to adjust to NO separation

This is my code for the layout

UICollectionViewFlowLayout *layoutItem=[[UICollectionViewFlowLayout alloc] init];
    layoutItem.sectionInset = UIEdgeInsetsMake(0, 0, 0, 0);

enter image description here So how can I set the separation on top / bottom to 0px? Between cells?,

thanks!
