UICollectionView显示与所选单元格相关的图像

Question

I have a CollectionView and what I want to do is when someone taps on one cell, this cell takes you a another view where it shows you all images related to the selected cell. My problem is that I am having trouble evaluating which one of all my cells is the selected cell, so I can assign in the next view all images related to the selected cell. I get an error with my the approach I am using...

Answer 1

let route = segue.destinationViewController as DetailCollectionViewController

if let indexPath = collectionView.indexPathsForSelectedItems()?.first as? NSIndexPath {
        switch indexPath.item {
        case 0:
                route.passedArray = detailCollection1
        case 1:
                route.passedArray = detailCollection2
        default:
                break
        }
}

/* for multiple selection

// iterate over the indexPathsForSelectedItems if it is not nil
for indexPath in collectionView.indexPathsForSelectedItems() as [NSIndexPath] {
    // do your wok
}

*/

Answer 2

indexPath.row is giving you the first cell. If you have more sections, use first indexPath.section to choose in what section you are selecting the cell.
