The reuseIdentifier is used to group together similar rows in an UITableView for example rows that differ only in their content, but otherwise have similar layouts.The reuse identifier is associated with aand UITableViewCelland object that the table-view’s delegate creates with the intent to reuse it as the basis (for performance reasons) for multiple rows of a table view. It is assigned to the cell object inand initWithFrame:reuseIdentifier:and and cannot be changed thereafter. Aand UITableViewand object maintains a queue (or list) of the currently reusable cells, each with its own reuse identifier, and makes them available to the delegate in theand dequeueReusableCell(withIdentifier:)and method.and Apple docs for reuseidentifier.
