Change Variable based on Cell Clicked

Question

I want to set a variable to different string when a certain CollectionView cell is tapped. So cell1 is tapped then var cellTapped = "cell1", cell 2 is tapped then var cellTapped = "cell2" and so on. It was suggested that I

"create a custom cell and hold the value as property and read this value on didSelectCell()"

but I'm not sure how to do this (newbie).

(Swift 3)

Answer 1

You need to set UICollectionViewDelegate to your ViewController and then implement didSelectItemAt IndexPath that gets called when a cell is tapped.

Something like this:

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    cellTapped = "cell" + String(indexPath.row)
}

You could also have an array of Strings and index into the array based on the indexPath.row:

let cellStringValues = ["cell1", "cell2", "cell3", ... , "celln"]

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    cellTapped = cellStringValues[indexPath.row]
}
