如何使用推键处理两个集合视图

Question

I'm having two UICollectionView

@IBOutlet weak var collectionView1: UICollectionView!

@IBOutlet weak var collectionview2: UICollectionView!

i'm getting indexPath for each collection view separately with functions.

func getIndexPathForSelectedCell() -> NSIndexPath?
{

    var indexPath:NSIndexPath?

    if collectionview1.indexPathsForSelectedItems()!.count > 0 {
        indexPath = collectionview1.indexPathsForSelectedItems()![0]
    }
    return indexPath
}

func getIndexPathForSelectedCell2() -> NSIndexPath?
{

    var indexPath2:NSIndexPath?

    if collectionView2.indexPathsForSelectedItems()!.count > 0 {
        indexPath2 = collectionView2.indexPathsForSelectedItems()![0]
    }
    return indexPath2
}

I'm Performing segue for cell touch as follows.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?)
{
    if let indexPath = getIndexPathForSelectedCell()
    {

        let DealsdetailViewController = segue.destinationViewController as! DealsDetailViewController

        DealsdetailViewController.Dealsdata = Dealsdata[indexPath.row]
    }
    else if let indexPath2 = getIndexPathForSelectedCell2()
    {

        let ContainerviewController = segue.destinationViewController as! ContainerViewController

        ContainerviewController.BTdata = BTdata[indexPath2.row]
    }
}

if i click on a cell in first collection view segue performs correctly, when i click on a cell in second collection view

i got error in

let DealsdetailViewController = segue.destinationViewController as! DealsDetailViewController

which is first if statement condition value, i'm stuck here

please help me, how to handle performing both segue on cell click on each collection view.

Use the method from UICollectionView protocol

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    let cell = cellForItemAtIndexPath(indexPath)!
    if collectionView == self.collectionView1 {
        self.performSegueWithIdentifier("segue1", sender: cell)
    } else if collectionView == self.collectionView2 {
        self.performSegueWithIdentifier("segue2", sender: cell)
    }
}

func prepareForSegue(segue: UIStoryBoardSegue, sender: AnyObject?) {
    if segue.identifer == "segue1" {
      let detailVC:DetailViewController = segue.destinationViewController as DetailViewController
      // Your sender is cell. You have indexPath of them and can get his identity in dataSource.
      //detailVC.name = ...
      //detailVC.surname = ...
    } else if segue.identifier == "segue2" {
      //...
    }
}
