How to programmatically select a row in UITableView in Swift

Question

I need to select a row in a UITableView programmatically using Swift 1.2.

This is the simple code:

var index = NSIndexPath(forRow: 0, inSection: 0)
         


        

Answer 1

Reusable function with validation of table size

Swift 4 and 5

This reusable function works and validate the size of table.

func selectRow(tableView: UITableView, position: Int) {
    let sizeTable = tableView.numberOfRows(inSection: 0)
    guard position >= 0 && position < sizeTable else { return }
    let indexPath = IndexPath(row: position, section: 0)
    tableView.selectRow(at: indexPath, animated: true, scrollPosition: .middle)
}

you can use it in this way

selectRow(tableView: myTableView, position: pos)

or you can implement this extension:

extension UITableView {
    func selectRow(row: Int, section: Int = 0) {
        let sizeTable = self.numberOfRows(inSection: section)
        guard row >= 0 && row < sizeTable else { return }
        let indexPath = IndexPath(row: row, section: section)
        self.selectRow(at: indexPath, animated: true, scrollPosition: .middle)
    }
}

and you can use it in this way:

mytableView.selectRow(row: pos, section: 0)

or

mytableView.selectRow(row: pos)
