navigate on click of collectionview cell inside tableview

Question

I have a tableview cell inside which i have added collectionview cell ( for horizontal scrolling).

Now i want to push to other navigation controller on pressing any

Answer 1

I think its better to use Notification in this case.

post a notification in didSelectItem of collection view

NSNotificationCenter.defaultCenter().postNotificationName(notificationIdentifier, object: nil)

and add an observer in viewController viewDidLoad as follows

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(pushToNew(_:)), name: notificationIdentifier, object: nil)

in the new pushToNew function, perform your segue

func pushToNew(notification: Notification) {
    // perform your segue here. Navigate to next view controller
}

Answer 2

First create protocol for delegation from CategoryRow.swift like below code

protocol CollectionViewSelectionDelegate: class {
    func didSelectedCollectionViewItem(selectedObject: AnyObject)
}

Now create delegate object on VideoCell.swift like below

weak var delegate:CollectionViewSelectionDelegate? 

Change ViewController.swift code before return cell

cell?.delegate = self

Override method of delegate in ViewController.swift and call similar method from VideoCell.swift from UICollectionView Delegate method.

Here you will get the cell click at the delegate method didSelectItemAtIndexPath on CategoryRow class and from there you can fire a delegate to get call inside ViewController ViewController.swift :

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! CategoryRow
            cell.delegate = self
            return cell
        }

VideoCell.swift :

    protocol CategoryRowDelegate:class {
    func cellTapped()
    }

CategoryRow.swift :

    class CategoryRow : UITableViewCell {
         weak var delegate:CategoryRowDelegate?
        @IBOutlet weak var collectionView: UICollectionView!
    }

     func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    if delegate!= nil {
    delegate?.cellTapped()
    }
    }

Add the delegate function inside ViewController

func cellTapped(){
//code for navigation
}

Answer 4

Make a protocol

protocol collectionViewCellClicked{
    func cellClicked()
}

• Implement this protocol in main View Controller Your View Controller look like this

  class ViewController: UITableViewController, collectionViewCellClicked{ func cellClicked(){ // Your Code  }}
  

• Your cellForRowAt delegate look like this

  override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: <#T##String#>, for: <#T##IndexPath#>) cell.delegate = self return cell }

• In your Table View Cell Make a variable of type collectionViewCellClicked var delegate: collectionViewCellClicked?

  and in your didSelectItemAt delegate

  func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { delegate.cellClicked() }
