let coupon_id : String = (sender.layer.valueForKey("coupon_id")) as! String
let user_id : String = (sender.layer.valueForKey("user_id")) as! String
if user_id == "empty" {
self.login()

let buttonRow = sender.tag
print(buttonRow)
}

i want to hide the add button when trigger. i just get the value of the indexPath but i dont know how to hide it without refresh the collectionview

Answer 1

Create a custom cell
class CustomCell: UICollectionViewCell {
#IBOutlet weak var label: UILabel!
#IBOutlet weak var delButton: UIButton!
#IBOutlet weak var addButton: UIButton!
#IBAction func addTapped(sender: AnyObject) {
delButton.removeFromSuperview()
addButton.removeFromSuperview()
}
}
Typical CollectionView Controller
class ViewController: UICollectionViewController {
override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 10;
}
override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! CustomCell
cell.label.text = "Cell \(indexPath.row)"
return cell
}
}
And your button will gone, when you hit them
