how to access custom view button action in main VC - ios

Question

I have created a custom view xib and give that view class. Now I take a view in main vc and give that class but now I want to access custom view button action method in my main vc. So how can I do that?
Here is my custom view
import UIKit
class TextCustomisationVC: UIView {
#IBOutlet var contentView: UIView!
override init(frame: CGRect) {
super.init(frame: frame)
self.commonInit()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.commonInit()
}
private func commonInit(){
Bundle.main.loadNibNamed("TextCustomisationVC", owner: self, options: nil)
addSubview(contentView)
contentView.frame = self.bounds
contentView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
}
#IBAction func btnCloseCustomisation_Click(_ sender: Any) {
}
#IBAction func btnApplyCustomisation_Click(_ sender: Any) {
}
}
Now I create an outlet in my main VC and give that same class I can access those class outlets but now I want to access above button action method So how can I do that?

Answer 1

You can use delegate here which you can implement in the main VC.
create a protocol like this:
protocol ButtonActionDelegate {
func closeButtonPressed(_ sender:UIButton)
func applyButtonPressed(_ sender:UIButton)
}
Then create instance of the delegate in your view like this:
var delegate:ButtonActionDelegate?
Implement this delegate in the main VC like this:
extension mainVC : ButtonActionDelegate {
func closeButtonPressed(_ sender: UIButton) {
}
func applyButtonPressed(_ sender: UIButton) {
}
}
Then you can call the delegate methods respectively like this:
#IBAction func btnCloseCustomisation_Click(_ sender: Any) {
self.delegate?.closeButtonPressed(sender)
}
#IBAction func btnApplyCustomisation_Click(_ sender: Any) {
self.delegate?.applyButtonPressed(sender)
}

You can try
let cusView = TextCustomisationVC(frame:///)
if btn sender is used inside function
cusView.btnCloseCustomisation_Click(cusView.closeBtn)
otherwise send any dummy button
cusView.btnCloseCustomisation_Click(UIButton())
Edit:
protocol CustomTeller {
func closeClicked(UIButton)
}
class TextCustomisationVC: UIView {
var delegate: CustomTeller?
#IBAction func btnCloseCustomisation_Click(_ sender: UIButton) {
self.delegate?.closeClicked(sender:sender)
}
}
// in mainVC
let cusView = TextCustomisationVC(frame:///)
cusView.delegate = self
and implement
func closeClicked(sender:UIButton) {
// close button called
}
