Swift 3. Trying to update from viewController some IBOutlets declared in prototype cell class

Question

I have cells in a tableView with 2 labels displaying text. Cells are managed in a detailCell class of type UITableViewCell, that references IBOutlets for both labels. This allows me to manage my prototype cell and display core data entries.

I added UITextField (with border style invisible) on top of each label and I would like to hide the label when user taps the textField and starts editing.

Problem is I cannot figure how to manage the label (referenced in the prototype class) from my viewController without referencing a second time the label in the viewController. Of course this fires the error: "Outlets cannot be connected to repeating content".

The other way round would be to hide/display label by managing it from the cell class, according to the var isEditing: Bool that I use in the viewController, but I do not manage to use it in the cell class.

Any ideas?

Answer 1

To achieve this you have to do something like below:

-> First of all you have to set all of your text fields delegate to self

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


let aCell : myCustomCell = tableView.dequeueReusableCell(withIdentifier: "aCell") as! myCustomCell

        aCell.txtView1.delegate = self
    return aCell    
    }

-> Secondly you have to get particular cell when user click on textfiels

     func textFieldDidBeginEditing(_ textField: UITextField) {

          //Get parent cell by traveling to the superview as your cell (Depends on your view hierarchy in your cell)
            let aCell : myCustomCell = textField.superview?.superview as! myCustomCell

//Hide below label
aCell.lblData.hidden = true

        }

--> Third, you have to hide text field and show label again when text field end editing get called

func textFieldDidEndEditing(_ textField: UITextField) {
        let aCell : myCustomCell = textField.superview?.superview as! myCustomCell

    //Hide below label
    aCell.lblData.text = textField.text
    aCell.lblData.hidden = false
    }
