UITableViewCell holding UICollectionView and click collection cell segue - ios

Question

I am using Swift3 and Xcode 8.3.3
I am working on UITableViewCell which hold UICollectionView.
Each CollectionView cell need to perform segue.
I mean, i need to call other ViewController with Navigation Controller. So user can back to Main UITableViewController.
import UIKit
class PastCell: UITableViewCell {
#IBOutlet weak var ptripDtls: UICollectionView!
var logcount:Int = 0
override func awakeFromNib() {
super.awakeFromNib()
ptripDtls.delegate = self
ptripDtls.dataSource = self
logcount = Transfer.tripObj[Transfer.cellpos]["logcount"]! as! Int
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
let width = self.ptripDtls.collectionViewLayout.collectionViewContentSize.width;
layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
layout.itemSize = CGSize(width: width-17 , height: 50)
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 1
ptripDtls!.collectionViewLayout = layout
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
extension PastCell: UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return logcount
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "PastTripCollectionCell", for: indexPath) as! PastTripCollectionCell
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
//Might be here segue function will call
}
}

Answer 1

You have actually multiple choices here:
Closure
Pass a closure inside the UITableViewCell like tapped: (Model) -> Void when you're dequeuing a tableView cell, and specify inside that closure to perform a segue. (it works if all your collection cells will perform a same segue, you can use this mechanism to propagate your callback if different segue's should get called)
Delegate
Define a custom delegate, to inform your viewController about CollectoinView's DidSelectItem method, and then perform Segue accordingly.
Notification
Trigger a Notification throughout the system which only your ViewController listens to that notification, and perform your segue accordingly. (This isn't actually a good solution, just pointing out that it's possible)

For swift 4 Use perform segue inside didSelectRowAtIndexPath if you are using segue
self.performSegue(withIdentifier: "YourSegueIdentifier", sender: nil)
and use Push if you are using only navigation controller.
let vc = self.storyboard?.instantiateViewController(withIdentifier: "YourVCIdentifier") as! YourVC
self.navigationController?.pushViewController(vc, animated: true)
