collectionView(_:shouldSelectItemAt:)

Declaration

optional func collectionView(_ collectionView: UICollectionView, shouldSelectItemAt indexPath: IndexPath) -> Bool

Parameters

• collectionView:

  The collection view object that is asking whether the selection should change.

• indexPath:

  The index path of the cell to be selected.

Return Value

true if the item should be selected or false if it should not.

Discussion

The collection view calls this method when the user tries to select an item in the collection view. It does not call this method when you programmatically set the selection.

If you do not implement this method, the default return value is true.
