Question

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

Answer 1

You can also do it a much simpler way using the collection view flow layout.

Set up the flow layout (remember to add the delegate in your header):

UICollectionViewFlowLayout * stickerFlowLayout = [[UICollectionViewFlowLayout alloc] init];

stickerFlowLayout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
**stickerFlowLayout.minimumLineSpacing = 10;**
stickerFlowLayout.minimumInteritemSpacing = 5;
stickerFlowLayout.sectionInset = UIEdgeInsetsMake(10, 25, 20, 25);

// Set up the collection view 
collectionView = [[UICollectionView alloc] initWithFrame:CGRectZero collectionViewLayout:stickerFlowLayout];
collectionView.delegate = self;
collectionView.dataSource = self;

etc

As you can see we can easily set the line spacing using:

**stickerFlowLayout.minimumLineSpacing = 10;**

We can also alter the other attributes

stickerFlowLayout.minimumInteritemSpacing = 5;

With the interitem spacing affecting the spaces between items (similar but different to the line spacing)

Using the flow layout you can save on a huge amount of code and set your collection view up programatically all in one place (just setting the inset and line spacing has immediately saved me two extra unneeded functions)
