How can I use pushViewController inside a cell Swift

I have a viewController where I have a tableview and inside every cell I have a collectionView.

I want to go to another view (where I will have a back button) so I tried to use my code which is working for the other views:

let vc =  self.storyboard?.instantiateViewController(withIdentifier: "detail") as! DetailView
    vc.name = beachesNames[indexPath.row]
    vc.imagak = imagesNames[indexPath.row]
    self.navigationController?.pushViewController(vc, animated: true)

But because this code is inside the TableViewCell I have an error that says:

Value of type 'HomeViewCell' has no member 'storyboard'

Is there any alternative parameter that I can use or something else it could do my task?

Thanks in advance.

- swift 3

let detailOrderVC = UIViewController()
self.viewController()?.navigationController?.pushViewController(detailOrderVC, animated: true)

- swift 4

in swift 4, you need to pass the viewcontroller to the cell like below

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cellId", for: indexPath) as! CustomTableViewCell

    // some your logic
    cell.viewController = self // CustomTableViewCell needs to have viewController member variable

    return cell
}

let detailOrderVC = UIViewController()
self.viewController?.navigationController?.pushViewController(detailOrderVC, animated: true)

If you are pushing to a view class that requires layout you must call layout at the same time. ex. 

 let layout = UICollectionViewFlowLayout()
 let nextViewclass = NextClass(collectionViewLayout: layout)
 self.navigationController?.pushViewController(nextViewclass, animated: true)

What you're missing is instantiating the storyboard:

let storyboard = UIStoryboard(name: "Main", bundle: nil)
storyboard.instantiateViewControllerWithIdentifier("myNavigationController") as! UINavigationController

But as this stackoverflow answer says, this generally isn't a good MVC design.

You might want to look into delegate patterns or using NotificationCenter. Both these ways essentially trigger a call to the parent view which will then handle the corresponding action.

If you have a collection view inside of every cell, then I would recommend having each cell hold a container view. The view controller associated with the container view will have a storyboard.

The code for the push would look a bit ugly: 

self.parent?.navigationController?.pushViewController(vc, animated: true)

The parent?. goes from the contained view controller to the parent view controller.
