iOS: Scroll one cell at a time

Question

I have horizontal scrolling set up now I would like for it to sort of scroll/snap one cell at a time when scrolling side to side.

Could someone shed some light? Here's the code I have so far:

- (void)viewDidLoad
{
    [super viewDidLoad];
}

#pragma mark - UICollectionView Datasource

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return 1;
}

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return 20;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    MyCell *cell = [cv dequeueReusableCellWithReuseIdentifier:@"MyCell" forIndexPath:indexPath];
    cell.backgroundColor = [UIColor whiteColor];
    return cell;
}

#pragma mark - UICollectionViewDelegateFlowLayout

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
    return UIEdgeInsetsMake(50, 20, 50, 20);
}

[collectionView setPagingEnabled:YES]; might do the trick?
