在自定义 UITableViewCell Swift 中点击多个按钮

Question

I have a custom UITableViewCell subclass where I am putting two buttons in the cell, I want both to be clickable, but so far I cannot even get any kind of click to trigger (besides row selection, but I disabled that on my UITableViewController subclass). Basically When one of two buttons is selected, it should remove those two buttons and update what is in the cell with a list of selectable choices (also buttons). I am doing everything programmatically (no IB).

My TableViewCell with Initial Two Buttons

I have looked around a lot and haven't found anything that handles more than ONE button in a tableViewCell. Currently I've been trying to add targets to my buttons in my UITableViewCell's awakeFromNib():

for button in initialChoiceButtons{
            button.isUserInteractionEnabled = true
            button.addTarget(self, action: #selector(initialChoicePressed(sender:)), for: UIControlEvents.touchUpInside)
        }

One thing I've tried is in my tableView in cellForRowAt for my custom cell is to bring my buttons to the front of the cell:

for button in (cell as! FormDropDownTableViewCell).initialChoiceButtons{
                    cell.bringSubview(toFront: button)
                }

I'm really stumped and feel like this should easy. I'm on the verge of just using a stackView inside of scrollview for everything...

Answer 1

Ok so I figured out a somewhat clean way to separate button taps in my tableviewcell, by creating a delegate protocol with a function that I'll call from my target in my tableviewcontroller for every button in my tableviewcell.

protocol UIButtonSelectorDelegate{
    func handleTap(button:DelegatingButton) //will select different functions based on DelegatingButton.actionType
}
class DelegatingButton:UIButton{
    var selectorDelegate:UIButtonSelectorDelegate?
    var actionType:String = "default"
}

in my FormDropDownTableViewCell I conform to the UIButtonSelectedDelegate and implement handleTap like so:

func handleTap(button:DelegatingButton){
        switch button.actionType{
        case "initialChoiceSelect":
            initialChoicePressed(initialChoice:button) //specific method for certain button.actionType also in my FormDropDownTableViewCell
        case "cardTypeSelect":
            cardTypeSelected(selectedCardType:button)
        default:
            break

        }
    }

Now I add the target-actions for every button in cellForRowAt in my tableviewcontroller like so:

button.addTarget(self, action: #selector(handleButtonTaps), for: UIControlEvents.touchUpInside)

and the handleButtonTaps func in the tableviewcontroller is simple:

func handleButtonTaps(sender: DelegatingButton){
        sender.selectorDelegate?.handleTap(button: sender)
    }

Enjoyed Talking to myself =P ..
