UITableViewRowAction vs UISwipeActionsConfiguration
(4 answers)
Closed 3 years ago.
I am trying to upgrade code of my project and found this warning
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let deleteRowAction = UITableViewRowAction(style: .destructive, title: deleteActionTitle) { [unowned self] (_, indexPath) in
//code you want to execute }
return [deleteRowAction]
}
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let contextItem = UIContextualAction(style: .destructive, title: deleteActionTitle) { (contextualAction, view, boolValue) in
//Code I want to do here
}
let swipeActions = UISwipeActionsConfiguration(actions: [contextItem])
return swipeActions
}
You can use the UISwipeActionsConfiguration over UITableViewRowAction such as
override func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
return UISwipeActionsConfiguration()
}

i am doing trailingSwipe to my tableview but it does not work. does not call the function trailingSwipeActionsConfigurationForRowAt.
try with the leadingSwipeActionsConfigurationForRowAt and if it works for me but not with trailingSwipe
valid that I have delegate and datasource the tableview
code
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let delete = UIContextualAction(style: .normal, title: "delete2") {(action, view, completionHandler) in
print("delete2 \(indexPath.row)")
}
let swipe = UISwipeActionsConfiguration(actions: [delete])
return swipe
}
Uses Apple Mac M1 ( MacBook Pro M1)
Try this, working fine on the Xcode 13+, Apple Mac M1 and Swift 5
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {}
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let delete = UIContextualAction(style: .destructive, title: "Delete") { (action, sourceView, completionHandler) in
// print("index path of delete: \(indexPath)")
completionHandler(true)
}
let edit = UIContextualAction(style: .normal, title: "Edit") { [weak self] (action, sourceView, completionHandler) in
completionHandler(true)
}
delete.title = ""
delete.image = UIImage(named: "deleteProfile")
edit.title = ""
edit.image = UIImage(named: "editProfile")
let swipeAction = UISwipeActionsConfiguration(actions: [delete,edit])
swipeAction.performsFirstActionWithFullSwipe = false // This is the line which disables full swipe
return swipeAction
}
I also faced this issue on my end.
Maybe this issue is with the Apple Mac M1 please try with the Apple intel.
Please check this question
Below code is working fine in my Apple Intel.
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let action = UIContextualAction(style: .destructive, title: "REMOVE") { [self] action, view, completion in
// Your swipe action code!
completion(true)
}
action.backgroundColor = UIColor.red
let swipeAction = UISwipeActionsConfiguration(actions: [action])
swipeAction.performsFirstActionWithFullSwipe = false // Full swipe disable
return swipeAction
}
I found a solution in Apple M1 please try it with the Real device.
I tried the above code on a real device it's working perfectly.
I am trying to make swipe-able table view cell for iOS 11 and above and trying to use the trailingSwipeActionsConfigurationForRowAt but it works on iPad and doesn't work on iPhone. It is not called in iPhone.
Surprisingly if I try to swipe the cell more then 10 or 20 times it sometimes works for once.
Here is my controller's table view extension
import UIKit
extension CustomViewController: UITableViewDelegate, UITableViewDataSource {
func initTableView() {
tableView.register(cell: SingleLineListItemViewCell.self)
tableView.delegate = self
tableView.dataSource = self
tableView.estimatedRowHeight = 64
tableView.rowHeight = UITableView.automaticDimension
tableView.backgroundColor = .green
tableView.isEditing = false
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let model = SingleLineListItemViewModel(title: "coko")
let cell = tableView.dequeueReusableCell(withIdentifier: SingleLineListItemViewCell.reuseIdentifier) as? SingleLineListItemViewCell
cell?.model = model
cell?.isFirst = indexPath.row == 0
cell?.isLast = indexPath.row == 2
return cell!
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
return nil
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 0
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 100
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return 64.0
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
print("didSelectRowAt....")
router?.routeToTransfer()
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
#available(iOS 11.0, *)
func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
return nil
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
// Action here
// In case of delete, you can simply do:
if editingStyle == .delete {
//Remove item at relative position from datasource array
//Reload tableview at the respective indexpath
}
}
#available(iOS 11.0, *)
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { _, _, _ in
//YOUR_CODE_HERE
}
deleteAction.backgroundColor = .red
let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
configuration.performsFirstActionWithFullSwipe = false
return configuration
}
}
Any help would be much appreciated.
The only obvious thing wrong with this is that you're not calling the completion handler. According to the API documentation it is necessary to call the completion handler to indicate whether the operation was successful. What it actually does I have no idea...
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { _, _, completionHandler in
//YOUR_CODE_HERE
completionHandler(true)
}
deleteAction.backgroundColor = .red
let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
configuration.performsFirstActionWithFullSwipe = false
return configuration
}
If this doesn't make any difference, do you have any other gesture recognisers that could be conflicting with the swipe action?
you can try this one
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String? {
return "Delete"
}
// this method handles row deletion
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
// remove the item from the data model
// delete the table view row
tableView.deleteRows(at: [indexPath], with: .fade)
} else if editingStyle == .insert {
// Not used in our example, but if you were adding a new row, this is where you would do it.
}
}
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let action = UIContextualAction(
style: .normal,
title: "Delete",
handler: { (action, view, completion) in
//do what you want here
completion(true)
})
action.backgroundColor = .red
let configuration = UISwipeActionsConfiguration(actions: [action])
configuration.performsFirstActionWithFullSwipe = false
return configuration
}
Here is are actions defined as well (point 1 and 2);
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .destructive, title: "") { _, _, completionHandler in
// 1. remove object from your array
scannedItems.remove(at: indexPath.row)
// 2. reload the table, otherwise you get an index out of bounds crash
self.tableView.reloadData()
completionHandler(true)
}
deleteAction.backgroundColor = .systemOrange
deleteAction.image = UIImage(named: "trash")
let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
configuration.performsFirstActionWithFullSwipe = true
return configuration
}
I'm trying to customize the where the delete option has a red background and a trash icon. So far from what I gathered and implemented I have a repeating image in the background and not sure how to make it red or show only 1 trash can image
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let title = " "
let deleteAction = UITableViewRowAction(style: .default, title: title) { (action, indexpath) in
}
let image = UIImage(named: "icon_trash")
if let im = image {
deleteAction.backgroundColor = UIColor(patternImage: im)
}
return [deleteAction]
}
I can see I'm close but not sure how to piece the color and what I have together to show something like the image below
I think it's time to upgrade to these ios 11 new methods with image property
public func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
public func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
So try this
func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .normal, title: "", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
// Call edit action
// Reset state
success(true)
})
deleteAction.image = UIImage(named: "icon_trash")
deleteAction.backgroundColor = .red
return UISwipeActionsConfiguration(actions: [deleteAction])
}
i'm trying to change the delete button of a cell.
I have 2 functions :
override func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let titleBtn = UITableViewRowAction(style: UITableViewRowActionStyle.default, title: "Supprimer") { (action , indexPath ) -> Void in
self.isEditing = false
//ackAction.backgroundColor = UIColor.orange
}
return [titleBtn]
}
override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
But, when I run my app, the text of the button is changed but the delete doesn't work (i can't delete data from my array and the row of my tableview). Before to add this functions all worked perfectly.
A detail: in the canEditRowAt function, I tried to return false too...
Thanks by advance
if you want to change the text of the delete button, conform this method in the UITableViewDelegate:
func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String?
{
return "Your new title"
}
To delete the item from the array conform this method
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath)
{
if (editingStyle == UITableViewCellEditingStyle.delete)
{
yourDataSourceArray.remove(at: indexPath.row)
yourTableView.reloadData()
}
}
You can either use default delete action and change its title like this.
func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String?
{
return "MyAction"
}
or you can create your own action buttons like this.
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let deleteAction = UITableViewRowAction(style: .default, title: "Delete") {action in
//handle delete
}
let editAction = UITableViewRowAction(style: .normal, title: "Edit") {action in
//handle edit
}
return [deleteAction, editAction]
}
So i've searched the site for an answer to this question and there are some decent results but nothing recent since Xcode 7 is no longer in beta and swift 2.0 is now the standard.
I've used the following code in order to make it so that a 'swipe left' feature will cause something to happen to a UITableViewCell -
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath){
if editingStyle == UITableViewCellEditingStyle.Delete {
// ...
}
}
I understand that this is something that Apple now supplied in their API and use of external classes is not needed.
I also understand you can customize the actions that come up from this swipe using this native code:
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
let more = UITableViewRowAction(style: .Normal, title: "More") { action, index in
print("more button tapped")
}
Is there any modern native code which would define a 'right swipe' on a UITableViewCell?
func tableView(_ tableView: UITableView,
leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
{
let closeAction = UIContextualAction(style: .normal, title: "Close", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("OK, marked as Closed")
success(true)
})
closeAction.image = UIImage(named: "tick")
closeAction.backgroundColor = .purple
return UISwipeActionsConfiguration(actions: [closeAction])
}
func tableView(_ tableView: UITableView,
trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
{
let modifyAction = UIContextualAction(style: .normal, title: "Update", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("Update action ...")
success(true)
})
modifyAction.image = UIImage(named: "hammer")
modifyAction.backgroundColor = .blue
return UISwipeActionsConfiguration(actions: [modifyAction])
}
The feature is available on iOS 11.0+ and Mac Catalyst 13.0+. For options on the left use the leading and on the right use the trailing methods.
Just implement the UITableViewDelegate methods and return your UISwipeActionsConfiguration object. You could optionally include an image or just the text as the title of the button.
func tableView(_ tableView: UITableView,
leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
func tableView(_ tableView: UITableView,
trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
Make sure to enable editing in your data source delegate otherwise the swipe options are disabled.
// True for enabling the editing mode
override func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
No, there Is no such native API as of now.
