I have in cell implement 3 buttons and button action. After call tableView.reloadData() can't click to any button in cell.
In controller in func cellForRow call cell?.onbuttonTappedAdd and other. Afer add element I call tabelViewReloadData.
//TableViewCell
var onButtonTappedAdd : (() -> Void)? = nil
var onButtonTappedRemove : (() -> Void)? = nil
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
func configureCell(orderitem: OrderItem){
self.orderItem = orderitem!
}
func setButtonGradient(){
}
#IBAction func changeValue(_ sender: Any) {
}
#IBAction func btnAddValue(_ sender: Any) {
if let onButtonTappedAdd = self.onButtonTappedAdd
{
onButtonTappedAdd()
}
}
#IBAction func btnRemoveValue(_ sender: Any) {
if let onButtonTappedRemove = self.onButtonTappedRemove {
onButtonTappedRemove()
}
}
//ViewControll cellForRow
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = tableViewOrderItem.dequeueReusableCell(withIdentifier: "OrderItemCheckoutCell", for: indexPath)
as? OrderItemCheckoutCell
var orderItem = GlobalArray.orderArrayList[indexPath.section].ListOrderItem[indexPath.row]
cell?.configureCell(orderitem: orderItem)
cell?.onButtonTappedAdd = {
GlobalArray.orderArrayList[indexPath.section].ListOrderItem[indexPath.row].quantity = GlobalArray.orderArrayList[indexPath.section].ListOrderItem[indexPath.row].quantity! + (GlobalArray.orderArrayList[indexPath.section].ListOrderItem[indexPath.row].Product?.bigValue)!
self.tableViewOrderItem.reloadData()
self.setTotalInfo()
}
cell?.onButtonTappedRemove = {

I want to trigger MultipleAnswerTableViewCell's mainSaveTapped func when the IBAction saveButton tapped.
Here is my class with the protocol
protocol AddQuestionViewControllerDelegate: AnyObject {
func mainSaveTapped()
}
class AddQuestionViewController: BaseViewController, MultipleAnswerTableViewCellDelegate, UITextFieldDelegate {
weak var delegate: AddQuestionViewControllerDelegate?
#IBAction func saveTapped(_ sender: UIButton) {
delegate?.mainSaveTapped()
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
switch cellTypes[indexPath.row] {
case .fixedTop: return configureFixedTop(indexPath: indexPath)
case .multiAnswer: return configureMultiAnswerCell(indexPath: indexPath)
case .singleAnswer: return configureSingleAnswerCell(indexPath: indexPath)
case .textAnswer: return configureTextAnswerCell(indexPath: indexPath)
}
}
func configureMultiAnswerCell(indexPath: IndexPath) -> MultipleAnswerTableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "MultipleAnswerTableViewCell") as! MultipleAnswerTableViewCell
cell.parentVC = self
cell.answerDelegate = self
cell.setupMultipleAnswerView()
return cell
}
And this is my MultipleAnswerTableViewCell
protocol MultipleAnswerTableViewCellDelegate: AnyObject {
func sendAnswers(surveyAnswers: [SurveyAnswer])
}
class MultipleAnswerTableViewCell: UITableViewCell, AddQuestionViewControllerDelegate, UITextFieldDelegate {
weak var answerDelegate: MultipleAnswerTableViewCellDelegate?
func mainSaveTapped() {
checkPostShare()
}
My func mainSaveTapped never triggered hence checkPostShare never called. What should I do to trigger mainSaveTapped func inside the MultipleAnswerTableViewCell
You don't assign a value to the delegate property inside the vc
weak var delegate: AddQuestionViewControllerDelegate?
So here delegate? is nil
#IBAction func saveTapped(_ sender: UIButton) {
delegate?.mainSaveTapped() // delegate? is nil
}
You need to send a message from the vc to the cell , here you don't need a delegate ,instead
#IBAction func saveTapped(_ sender: UIButton) {
(tableView.visibleCells as? [MultipleAnswerTableViewCell])?.forEach { cell in
cell.mainSaveTapped()
}
}
check / uncheck the check box by tapping the cell in table view and how to know which cell has checked or unchecked inside Expandable drop down in Swift.

I try to use delegate to send data from textField which is in the Detail2(ViewController) to array which is in the ViewController.
I used here print method and first print show that one element has been added to the array but the second print method which is below the ViewVillAppear() show that array is empty. How? I want to be able to to use delegate to add data to my table.

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet var add: UIBarButtonItem!
#IBOutlet var tv: UITableView!
var array :[String] = []
override func viewDidLoad() {

}
override func didReceiveMemoryWarning() {

}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "segue" {

}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)

func tekst(data: String) {

class Detail2: UIViewController {
var delegate: Data? = nil
#IBAction func btn(_ sender: Any) {
let sb = storyboard?.instantiateViewController(withIdentifier: "Main" ) as! ViewController
navigationController?.pushViewController(sb, animated: true)
if delegate != nil {
if txtfield.text != nil {
let napis = txtfield.text
delegate?.tekst(data: napis!)
}
}
}
#IBOutlet var btn: UIButton!

Just update your function with:
#IBAction func btn(_ sender: Any) {
if delegate != nil {
if txtfield.text != nil {
let napis = txtfield.text
delegate?.tekst(data: napis!)
}
navigationController?.popViewController(animated: true)
}
}
Update:
extension ViewController: Data {
func tekst(data: String) {
array.append(data)
print(array)
self.tv.reloadData()
}
}
You need to add this delegate?.tekst(data: napis!) inside completion handler, because you are using navigationController, there is no option for completion handler,So have to add UINavigationController extension like that:
extension UINavigationController {
public func pushViewController(viewController: UIViewController,
animated: Bool,
completion: (() -> Void)?) {
CATransaction.begin()
CATransaction.setCompletionBlock(completion)
pushViewController(viewController, animated: animated)
CATransaction.commit()
}
}
change this
navigationController?.pushViewController(sb, animated: true){
if delegate != nil {
if txtfield.text != nil {
let napis = txtfield.text
delegate?.tekst(data: napis!)
}
Update your code in Detail2 viewcontroller
#IBAction func btn(_ sender: Any) {
if delegate != nil {
if txtfield.text != nil {
let napis = txtfield.text
delegate?.tekst(data: napis!)
}
}
navigationController?.popViewController(animated: true)
}
In the ViewController implement the delegate method
func tekst (data: String) {
array.append(data)
}
// in detail
#IBAction func btn(_ sender: Any) {
if txtfield.text != nil {
let napis = txtfield.text
delegate?.tekst(data: napis!)
}
/// dismiss detail here don't push main again
self.navigationController?.popViewController(animated: true)
}
I have UITableView embed inside a main UIView. My problem is when I click on a cell to select items, it is not responding to the selection or triggering the segue.
Note: In attributes inspecter
is selection supposed to be set to single selection?
Update Note: the prepareForSegue function is not triggering or print "test".

In this answer I am making the assumption that didSelectRowAtIndexPath is firing.
In your didSelectRowAtIndexPath, you need to fire the segue that you created from the cell to the second view controller:
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("selected row", indexPath)
performSegue(with: "segueIdentifier")
}
I'm not sure what version of Swift you are using, so you might need to make some slight changes.
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
//self.performSegue(withIdentifier: "sites", sender: self)
self.performSegue(withIdentifier: "CHANGE-TO-YOUT-SEGUE-ID", sender: self)
}
is the "hello" get printed? if so, call your segue from this point. Don't forget to connect your segue (from the top left square) in the story board as manual segue:
If func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) is not called at all, your problem is that the delegate of your UITableView is not set (or not correctly set). The delegate should be your EditNpFormViewController.
You can easily set the delegate of your UITableView instance by simply Control-dragging from the table to the controller that contains it (inside the Storyboard). The other simple way is by setting
tableView.delegate = self
You can just select the table inside the storyboard and drag the delegate from the right panel's circle to your controller:
If your delegate is set right, check the selection attribute of the cell itself:
If your table view is in editing mode, you need to set tableView.allowsSelectionDuringEditing = true
So i have created an app where users create custom workouts.
You enter the first view add a x number of rounds,than you click on a button in the tableview where you add rounds.That click opens another activity with a collectionview.
So the problem is here when i click on an element witch represents the exercise that needs to be in the round it sends me an empty result.By default if i add a value to that string it works.
I have noticed that the unwind happens before my didSelectItemAtIndexPath

Here is how unwinding works:
First, put your IBAction unwind(segue:UIStoryboardSegue) in the vc where you intend to go back (presenter vc, InsertWorkout in this case).
Second, go to storyboard and choose the vc where you'll unwind from (collection view in this case) and ctrl-drag from the button/cell that causes the unwind (collection view cell in your case) to the exit button on top of that same vc and you should see a pop-up with your IBAction unwind method name under 'Selection Segue'.
Third, implement prepareforsegue in the current vc (collection vc in this case) to pass your data back.
class InsertWorkout
{
IBAction func unwind(segue:UIStoryboardSegue) {
//use the data passed from prepare to update your ui or you can also communicate to the sender using segue.sourceVC
}
}
class CollectionVC
{
override func prepareForSegue(segue: UIStoryboadSegue, sender: AnyObject?){
if segue.identifier == "whatever you put in storyboard for segue id" {
if let inserWorkoutVC = segue.destinationViewController as? InsertWorkout {
//pass the data here but don't attempt to update your destination's view ui!!,
}
}
}
}
