Swift 4.2 Delegate and Protocol no working












2















I have UIViewController(profileViewController) in which there is collectionView, the collectionView have headerCell in which there is segmentedControl, when the segmentedControl value change, i want to tiger the delegate method but it not working, here is the code,
this is the class of collectioview headercell, and protocol.



import UIKit

// Protocol

protocol headerCellSegmentedDelegate {
func changeTabe(whichOne : String)
}

// HeaderCell Class

class HeaderProfileCollectionReusableView: UICollectionReusableView {
var headerDelegate : headerCellSegmentedDelegate?
@IBAction func changeValue(_ sender: UISegmentedControl) {
if sender.selectedSegmentIndex == 0 {
headerDelegate?.changeTabe(whichOne: "0")
}else{
headerDelegate?.changeTabe(whichOne: "1")
}
}
}


In the same UIViewController(profileViewController) which have the collectionView



    // profileViewController 
import UIKit
import SideMenu

class profileViewController: UIViewController {

//let headdercell = HeaderProfileCollectionReusableView()
@IBOutlet weak var collectionView: UICollectionView!
override func viewDidLoad() {
super.viewDidLoad()
// headdercell.headerDelegate = self //still not working with this too
setupSideMenu()
// Do any additional setup after loading the view.
}
}
extension profileViewController : headerCellSegmentedDelegate {
func changeTabe(whichOne: String) {
print("which tab " + whichOne)
}
}


i Try with protocol with class and weak, but still not working.

First of all your code



//let headdercell = HeaderProfileCollectionReusableView()


shouldn't be commented.



Second, after you uncomment that, assign headerDelegate value to self.



headdercell.headerDelegate = self
