Swift UITableView custom Cell ordering Drag Drop? - ios

Question

i am trying to resort UITableView cell's by long press then drag and drop the cell , its not working when i use Custom cell view any idea why !
Here is the TableView viewcontroller :
override func viewDidLoad()
{
super.viewDidLoad()
// Then delegate the TableView
self.tableView.delegate = self
self.tableView.dataSource = self
// Register table cell class from nib
let bundle = Bundle(for: type(of: self))
let cellNib = UINib(nibName: "tbc_song_vertical", bundle: bundle)
self.tableView.register(cellNib, forCellReuseIdentifier: "tbc_song_vertical")
//Loading Template
let nib_tbc_loading = UINib(nibName: "tbc_loading", bundle: bundle)
self.tableView.register(nib_tbc_loading, forHeaderFooterViewReuseIdentifier: "tbc_loading")
//Automated ell height
self.tableView.estimatedRowHeight = 44.0
self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.reloadData()
self.tableView.isEditing = true
}
// MARK: - Sorting
func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCellEditingStyle {
return .none
}
func tableView(_ tableView: UITableView, shouldIndentWhileEditingRowAt indexPath: IndexPath) -> Bool {
return false
}
func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
let movedObject = self.data[sourceIndexPath.row]
data.remove(at: sourceIndexPath.row)
data.insert(movedObject, at: destinationIndexPath.row)
// To check for correctness enable: self.tableView.reloadData()
}
//loading footer
func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let footerView = self.tableView.dequeueReusableHeaderFooterView(withIdentifier: "tbc_loading") as! tbc_loading
footerView.startAnimate()
return footerView
}
//loading footer
func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return ( self.is_fetching ) ? 40 : 0
}
//Pagination
func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {
//Bottom Refresh
if scrollView == tableView{
if ((scrollView.contentOffset.y + scrollView.frame.size.height) >= scrollView.contentSize.height )
{
}
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return data.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell : tbc_song_vertical = tableView.dequeueReusableCell(withIdentifier: "tbc_song_vertical", for: indexPath) as! tbc_song_vertical
cell.fillwithInfo(dto: self.data[indexPath.row] )
return cell
}
// Tabbed Cell
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { }
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
}
only if i use custom view its not working , but when i hold my finger on the right side of any cell to drag it up or down its dragging all the table

Answer 1

Add the following method
func tableView(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool {
return true
}
