EPSCollectionViewFormLayout

EPSCollectionViewFormLayout is a subclass of UICollectionViewLayout that makes it easy to layout forms, like login and address forms, in a collection view.

For an example of how to use EPSCollectionViewFormLayout, see the example project.

When using EPSCollectionViewFormLayout, each section in the collection view is laid out in one row. Your collection view’s delegate must implement the two methods in the EPSCollectionViewFormLayoutDelegate protocol:

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout heightForSectionAtIndex:(NSInteger)section;

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout relativeWidthOfItemAtIndexPath:(NSIndexPath *)indexPath;

The widths returned in collectionView:layout:relativeWidthOfItemAtIndexPath: are relative to the width of the collection view, so returning 0.5 would make the cell at that indexPath be half the width of the collection view.
