import UIKit
class ViewController: UIViewController ,UICollectionViewDelegate&UICollectionViewDataSource&UICollectionViewDelegateFlowLayout{
#IBOutlet weak var collectionView: UICollectionView!
var currentIndexPath:IndexPath!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
collectionView.delegate = self
collectionView.dataSource = self
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 10
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath)
cell.backgroundColor = indexPath.row % 2 == 1 ? .blue : .red
return cell
}
func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
currentIndexPath = indexPath
}
#IBAction func indexPathAction(_ sender: UIButton) {
print("Current IndexPath",currentIndexPath)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return collectionView.bounds.size
}
}

Create custom cell with button, give button action programatically, give tag values for button & superView like the below.
Implement button action, you can able to get index like below.
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath)
cell.button.superview.tag = indexPath.section
cell.button.tag = indexPath.row
cell.button.addTarget(self, action: #selector(self.buttonAction), for: .touchUpInside)
return cell
}
func buttonAction(_ sender:UIButton) {
let indexPath = IndexPath(row: sender.tag, section: sender.superview!.tag)
}

Answer 3

Try This
you set your cell button in cellForItemAt indexPath like this
cell.btnCancel.tag = indexPath.row
cell.btnCancel.addTarget(self, action:#selector(btnCancel), for:.touchUpInside)
//And catch your value like this
#objc func btnCancel(sender: UIButton)
{
let index = [sender.tag] as IndexPath
let dict = self.yourarray[sender.tag] as! NSDictionary
}

Answer 4

You can assign a tag to button and retrieve indexpath from the tag in action of the button.
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath)
cell.button.tag = indexPath.row
cell.button.addTarget(self, action: #selector(buttonTapped(sender:)), for: UIControl.Event.touchUpInside)
return cell
}
#objc func buttonTapped(sender:UIButton){
let indexPath = Indexpath(row:sender.tag , section: 0)
let cell = collectionView.cellForItem(at:indexPath)
}
Hope this helps!
