UICollectionView - Horizontal scroll, horizontal layout?

Question

I have a UIScrollView that lays out a grid of icons. If you were to imagine the layout for the iOS Springboard, you'd be pretty close to correct. It has a horizontal, paged scroll (just like Springboard). However, it appears that the layout is not quite right. It appears as though it is laying out the items from top to bottom. As a result, my last column only has 2 rows in it, due to the number of items to be displayed. I'd rather have my last row on the last page have 2 items, like you would see in the Springboard.

How can this be accomplished with UICollectionView and its related classes? Do I have to write a custom UICollectionViewFlowLayout?

Answer 1

Have you tried setting the scroll direction of your UICollectionViewFlowLayout to horizontal?

[yourFlowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal]; 

And if you want it to page like springboard does, you'll need to enable paging on your collection view like so:

[yourCollectionView setPagingEnabled:YES];
