We are trying to make a collection view. In each cell the users can choose an image and enter text into a text field. We noticed that after adding four cells, when we add a new cell, the text field is already filled with the information from previous cells. In our code, we never programmatically fill the text field (which starts out empty), we allow the user to do this. Any suggestions?
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("Image", forIndexPath: indexPath) as! CollectionViewCell
cell.deleteButton?.addTarget(self, action: #selector(AddNewItem.xButtonPressed(_:)), forControlEvents: UIControlEvents.TouchUpInside)
cell.deleteButton?.layer.setValue(indexPath.row, forKey: "index")
let item = items[indexPath.item]
let path = getDocumentsDirectory().stringByAppendingPathComponent(item.image)
cell.imageView.image = UIImage(contentsOfFile: path)
cell.imageView.layer.borderColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.3).CGColor
cell.imageView.layer.borderWidth = 2
cell.layer.cornerRadius = 7
return cell
}
Problem is that you are using dequeReusableCellWithIdentifier which returns already created cell(that you were using before). That's why it's already filled with previous data. You need to clear this data before showing this cell, or fill it from some storage(for example array that represents your collection view cells(each object in array somehow related to cell, in your case that is text wroten in cell))
