Try this for Objective c

Add below code at cellForRowAtIndexPath

cell.btnOk.tag = indexPath.row ;
[cell.btnOk addTarget:self action:@selector(OkBtnAction:) forControlEvents:UIControlEventTouchUpInside] ;

Than add the action of that button

-(IBAction)OkBtnAction:(id)sender
{
    UIButton* btn=(UIButton*)sender;
    NSLog(@"row: %ld",(long)btn.tag);

}

Create a custom UICollectionViewCell type. Wire up an IBAction to the cell.

Create a protocol that lets the cell notify the collection view that the user tapped a button. Have the action pass the tap to the delegate.

In your cellForItemAt() method, set the view controller as the delegate.

Now in your view controller handle the tap as desired.

Use addTarget of your button inside cellForItemAt:indexPath datasource and add a selector where action of the button will be defined. Add this button's tag, (add it same as your indexPath.row, that you can use to differentiate your button from collectionview)

cell.yourButton.addTarget(self, action: #selector(yourButtonTapped), for: .touchUpInside)
cell.yourButton.tag = indexPath.row

Now add the action of that button and inside that perform any action you need.

@IBAction func yourButtonTapped(_ sender: UIButton) {
    //perform action
}
