Kuidas tagada tabeli lahtrite korduvkasutus ressurside optimeerimiseks?

In iOS, the mechanism for reusing cells in a table uses cell reuse identifiers.

Main steps:

1. Register the cell class or nib with a unique identifier.
2. In the tableView(_:cellForRowAt:) method, call dequeueReusableCell(withIdentifier:) to get a reusable cell.
3. Configure the cell with the current data.

This allows not to create a new cell for each row, but to reuse existing ones, saving memory and improving performance.

Example in Swift:

let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath)
cell.textLabel?.text = data[indexPath.row]
return cell

This way, the system manages a pool of cells and reuses them as the table scrolls.
