I’m trying to capture an event from a button pressed so I can pass it to a table view, its a timer where I can capture the time and pass it to the tableview but I can't seem to be able to capture the event type.
In the example below I can capture the time a goal was scored but I need the words Goal also passing to the tableview
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell(style: UITableViewCellStyle.value1, reuseIdentifier: "cell")
cell.backgroundColor = self.view.backgroundColor
**cell.textLabel?.text = "Help here to capture the button event"**
cell.detailTextLabel?.text = time[indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return time.count
}
#IBAction func goalClicked(_ sender: UIButton) {
let stopWatchString = stopWatch.elapsedTimeSinceStart()
stopwatchLabel.text = stopWatchString
time.insert(stopWatchString, at: 0)
self.tableView.reloadData()
}
Thanks
Sorted it.
var event: String!
then in the tableView
cell.textLabel?.Text = event
Finally in the button function
event = "Goal"
tableView.reloadData()

I want when scrolling to bottom in UITableView Fetch more date from API based on Page Number
Are use this method
func scrollViewDidScroll(_ scrollView: UIScrollView) {
if (((scrollView.contentOffset.y + scrollView.frame.size.height) > scrollView.contentSize.height ) && ! isLoadingList){
self. isLoadingList = true
self. loadMoreItemsForList()
}
}
or used this method
override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
// fetch new data if user scroll to the last cell
guard isLoadingIndexPath(indexPath) else { return }
if self.totalItems > orders.count {
fetchNextPage()
}
}
use func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) method to fetch more data while scrolling to bottom.
I use below code for get selected items of tab bar controller. My UITabbar has 7 view controllers(there are 3 items in More tab).
this code work only for 5 tabs but it don`t return selected index of items on More!
import UIKit
class CustomTabbarController: UITabBarController{
override func viewDidLoad() {
super.viewDidLoad()
self.delegate = self
}
override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
print(self.selectedIndex)
}
}
Following code worked for me. I had to redesign moreTableView to follow my app design. Function 'didSelectRowAt' returns what index is selected.
This code is added to 'UITabBarController' class.
var moreTableView: UITableView?
weak var currentTableViewDelegate: UITableViewDelegate?
func customizeMoreTableView() {
moreTableView = moreNavigationController.topViewController?.view as? UITableView
currentTableViewDelegate = moreTableView?.delegate
moreTableView?.delegate = self
moreTableView?.dataSource = self
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return (viewControllers?.count ?? 4) - 4
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let moreCell = UITableViewCell()
let item = viewControllers?[indexPath.row + 4].tabBarItem
moreCell.textLabel?.text = item?.title
moreCell.textLabel?.textColor = .white
moreCell.imageView?.image = item?.image
moreCell.imageView?.tintColor = .white
moreCell.backgroundColor = .black
return moreCell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
currentTableViewDelegate?.tableView!(tableView, didSelectRowAt: indexPath)
}
Get selected item like this :
override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
print(tabBar.items?.index(of: item))
}
I am trying to make it when the users clicks on Button in a table view cell it takes them to a new view controller related to the current cell.
Try the below code,
Do this in cellForRowAt indexPath,
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell_Identifier", for: indexPath) as! UITableViewCell
cell.myButton.isUserInteractionEnabled = true
cell.myButton.tag = indexPath.row
cell.myButton.addTarget(self, action: #selector(didTapMyButton(_:)), for: UIControlEvents.touchUpInside)
return cell
}
And here is the button action,
func didTapMyButton(_ sender : UIButton) {
let selectedIndex = sender.tag // You can get index here, so according to the index you can navigate to particular ViewController
let nextVC = self.storyboard?.instantiateViewController(withIdentifier: "UIViewController_identifier") as! UIViewController
self.present(nextVC, animated: true, completion: nil)
}
Hope it helps ..
It's been awhile since I've made a fool of myself here, so here goes again as I'm still trying to learn and feel as though I'm chasing my tail on this project.
With that said, ultimately I would like to get Jerkoch's SwipeCellKit to work, but not necessary at this point as I just need to figure out how to add more options other than just the 'delete' cell action.

I loose my data if I set the delegate property on tableView from
let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! CommentTableViewCell
to
let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! SwipeTableViewCell
Here is my CommentViewController Code:
import UIKit
import SwipeCellKit
class CommentViewController: UIViewController {
var postId: String!
var comments = [Comment]()
var users = [User]()
override func viewDidLoad() {
super.viewDidLoad()
tableView.tableFooterView = UIView(frame: CGRect.zero)
tableView.separatorInset = UIEdgeInsets.zero
tableView.dataSource = self
tableView.estimatedRowHeight = 100
tableView.rowHeight = UITableViewAutomaticDimension
loadComments()
}
func loadComments() {
Api.Post_Comment.REF_POST_COMMENTS.child(self.postId).observe(.childAdded, with: {
snapshot in
Api.Comment.observeComments(withPostId: snapshot.key, completion: {
comment in
self.fetchUser(uid: comment.uid!, completed: {
self.comments.append(comment)
self.tableView.reloadData()
})
})
})
}
func fetchUser(uid: String, completed: #escaping () -> Void ) {
Api.User.observeUser(withId: uid, completion: {
user in
self.users.append(user)
completed()
})
}
}
extension CommentViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return comments.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CommentCell", for: indexPath) as! CommentTableViewCell// Can't update this to SwipeTableViewCell - Will loose data
cell.selectedBackgroundView = createSelectedBackgroundView()
let comment = comments[indexPath.row]
let user = users[indexPath.row]
cell.comment = comment
cell.user = user
cell.delegate = self
return cell
}
}
extension CommentViewController: SwipeTableViewCellDelegate{
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> [SwipeAction]? {
guard orientation == .right else { return nil }
let deleteAction = SwipeAction(style: .destructive, title: "Delete") { action, indexPath in
// handle action by updating model with deletion
}
// customize the action appearance
deleteAction.image = UIImage(named: "delete")
let flagAction = SwipeAction(style: .destructive, title: "Flag") { action, indexPath in
// handle action
}
deleteAction.image = UIImage(named: "flag")
let blockAction = SwipeAction(style: .destructive, title: "Block") { action, indexPath in
// handle action
}
deleteAction.image = UIImage(named: "block")
return [deleteAction, flagAction, blockAction]
}
}
I've even tried something like the following:
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
// THIS GIVES THE DEFAULT 'DELETE' ACTION
print("Commit editingStyle")
}
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
print("editActionsForRowAtIndexPath")
let blockAction = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Block", handler: { (action:UITableViewRowAction, IndexPath:IndexPath) in
//self.isEditing = false
print("Block action Pressed")
})
let flagAction = UITableViewRowAction(style: UITableViewRowActionStyle.normal, title: "Flag", handler: { (action:UITableViewRowAction, IndexPath:IndexPath) in
print("Flag action Pressed")
})
let deleteAction = UITableViewRowAction(style: UITableViewRowActionStyle.destructive, title: "Delete", handler: { (action:UITableViewRowAction, IndexPath:IndexPath) in
print("Delete action Pressed")
})
return [blockAction, flagAction, deleteAction]
}
No matter what I do, I can't get more than just the generic 'Delete' action to show on a swipe action.
I don't even think the following function is being called/referenced:
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
What am I doing wrong, or what do I need to CUD to get 3 swipe actions; Delete, Flag and Block, to make Apple happy for my next submission.
Thank you all in advance!
This question is outdated but i'll write the answer which i think would have done the trick :)
You should be using UITableViewController not UIViewController for your view. SwipeCellKit only works with TableViewControllers.
I'm trying to pass data from tableView1 and tableView2 one at a time to MainVC via segues from textfields, the problem is MainVC.textField is not keeping the value of the previous tableView data, looks like is creating a new MainVC all the time, here is the code from the tableView which is the same for the second tableView.
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let indexPath = self.itemTableView.indexPathForSelectedRow
let currentCell = tableView.cellForRow(at: indexPath!) as! ItemCell
itemToPass = currentCell.itemName?.text
performSegue(withIdentifier: "toEnterItem", sender: self)
}
and
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "toEnterItem" {
let enterItemVC = segue.destination as! MainVC
MainVC.passedItem = itemToPass
}
}
Any help will be appreciated. Thanks
Problem solved, I used protocols to temporarily persist the data in textfields after segue.
protocol sendName {
func sendToLastVC{name: String)
}
