This `UICollectionView` subclass allows for partial layout invalidation using `IGListCollectionViewLayout`.
|
|
|
|
@note When updating a collection view (ex: calling `-insertSections`), `-invalidateLayoutWithContext` gets called on
|
|
the layout object. However, the invalidation context doesn't provide details on which index paths are being modified,
|
|
which typically forces a full layout re-calculation. `IGListCollectionView` gives `IGListCollectionViewLayout` the
|
|
missing information to re-calculate only the modified layout attributes.
