UICollectionView: One Row or Column

I want to use

to display a horizontal scrollable list of thumbnails, however, I want this to be a single row. On another view, I'm displaying the thumbnails in a
but this one scrolls vertically and it's in a single column.

Currently, the way I'm doing this is by changing the size of the collection view to only be big enough for one item so it autowraps and works, but now I'm dealing with variable sized items so it doesn't work anymore.

How do you make a
display one row or column?

I am guessing you are using the built in Flow Layout. However, for your case, you should make a custom UICollectionView Layout. Make it subclass of UICollectionViewFlowLayout and add this code in the init method:

- (id)init {
    if ((self = [super init])) {
        self.scrollDirection = UICollectionViewScrollDirectionHorizontal;
        self.minimumLineSpacing = 10000.0f;
    return self; 

The minimumLineSpacing is the key to making it have one line here.

I hope this helps!
