How to determine which cell is being viewed or clicked in a collection view

I want to be able to edit records that are displayed in a collection view.

I've added an "Edit" button to the collection view. What is the best way to determine which cell is to be edited?

I thought of doing something like so:

func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
 visibleCell = collectionView.visibleCells().first as MessageCell
}

I didn't want to add the edit button to the xib itself as I don't want the button to scroll when the cell scrolls

One possibility is to have a variable in your ViewController called something like isEditing. This will be set to true when the edit button is clicked.

Then, set your collection view's delegate to self.

Implement this method: func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath), A UICollectionViewDelegate method.

In the method, write something like:

if isEditing{
    // What happens when selected and editing
} else{
    // What happens when selected and not editing
}
