Reuse

Why? Memory. Allows you to have a table with thousands of cells without having thousands of cell objects in memory

UITableViewCell

Styles

(IB -> enum)

• Basic (.default) - no detail
• Right Detail (.value1) - detail is gray and on the right
• Left Detail (.value2) - detail is on the right and label is blue, no image space
• Subtitle (.subtitle) - detail is below and smaller text

Concepts

• contentView - the main contents - will be resized in editing mode
• accessory view - the thing to the right

Mutation

Add

tableView.insertRows(at: [indexPath], with: .automatic)

Move

override func tableView(_ tableView: UITableView,
                        moveRowAt sourceIndexPath: IndexPath,
                        to destinationIndexPath: IndexPath) {
    // change in underlying data
}

Delete

override func tableView(_ tableView: UITableView,
                        commit editingStyle: UITableViewCell.EditingStyle,
                        forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        // change in underlying data
    }
}
