- tableView编辑练习 及左右侧划功能：
- 右划置顶：
func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let actionTop = UIContextualAction(style: .normal, title: "置顶") { (action, view, finished) in
let first = IndexPath(row: 0, section: 0)
tableView.moveRow(at: indexPath, to: first)
finished(true)
}
actionTop.backgroundColor = UIColor.orange
return UISwipeActionsConfiguration(actions: [actionTop])
}
- 左划删除：
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let actionDel = UIContextualAction(style: .destructive, title: "删除") { (action, view, finished) in
self.ints.remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: .fade)
finished(true)
}
actionDel.backgroundColor = UIColor.red
return UISwipeActionsConfiguration(actions: [actionDel])
}
- 编辑：
需要先设置实现代理方法canEditRowAt，返回值为true，练习中因为需要移动cell所以也需要实现canMoveRowAt，并实现moveRowAt方法：
func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
let fromRow = (sourceIndexPath as NSIndexPath).row
let toRow = (destinationIndexPath as NSIndexPath).row
let int = ints[fromRow]
ints.remove(at: fromRow)
ints.insert(int, at: toRow)
}
