Placing a margin around each edge of the UICollectionView

Question

When the UICollectionView is populated with items they always go right to the edges of the UICollectionView like so:

---------------
|X X X X X X X|
|X X X X         


        

Answer 1

You can pretty much control every aspect of the grid with collectionview's protocol. Here's an example:

- (UICollectionViewFlowLayout *)collectionViewFlowLayout
{
    UICollectionViewFlowLayout *flowLayout = [UICollectionViewFlowLayout new];
    flowLayout.itemSize = CGSizeMake(180, 255);
    flowLayout.sectionInset = UIEdgeInsetsMake(10, 30, 0, 30);
    flowLayout.minimumInteritemSpacing = 0.0f;
    flowLayout.minimumLineSpacing = 0.0f;
    flowLayout.scrollDirection = UICollectionViewScrollDirectionVertical;
    return flowLayout;
}

The one you would want to change in your case is the sectionInsets
