clearsSelectionOnViewWillAppear is a boolean property of
UICollectionViews. It's set on
true by default. According to the Apple Reference
a Boolean value indicating if the controller clears the selection when the table appears.
This is still not clear to me. I suppose "clearing the selection" means that the
UITableView does not have any selected (highlighted)
UITableViewCells when the
UITableView receives a
viewWillAppear: message. I do not think this is the right answer, though.
What is the
clearsSelectionOnViewWillAppear property for?
