UIcollectionview Custom Cell class to didselectitem at - ios

Question

my collectionview contains multiple custom cell class that created programmatically. Fun part is I will have a cell that contains another collectionview inside of it. So how to click into this collectionview to present a new view controller? Below are my sample codes on how to create the cell.
class MainView: UIViewController {
** main view to display UIcollectionview **
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: userCellIdent, for: indexPath) as! UserContainerViewCell
cell.Users = users * to display users array*
return cell
}
class UserContainerViewCell: UICollectionViewCell{
* the uicollectionview that inside a cell , also contains extension to UIcollectioview datasource and delegate to display the cells within this cell*
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: ident, for: indexPath) as! userCell
let user = featureUsers![indexPath.row]
cell.config(withUser: user)
return cell
}
}
class userCell: UICollectionViewCell {
func config(withUser: UserProfile) { }
** cell class to display the info from the user array **
}
So with this setup, how to click into the cell and present a new controller with the User info in the array?

Answer 1

You have to pass a delegate or hit notification to viewController on didSelect of internal collectionViewCell and in that method you can present new view controller .

Answer 2

You can try
class UserContainerViewCell: UICollectionViewCell {
var myInstance: MainView!
}
class MainView: UIViewController {
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: userCellIdent, for: indexPath) as! UserContainerViewCell
cell.myInstance = self
}
}
then inside didSelectItemAtRow
let vc = myInstance.storyboard?.instantiateViewController(withIdentifier: "infoView") as! InfoController
vc.providesPresentationContextTransitionStyle = true;
vc.definesPresentationContext = true;
vc.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
myInstance.present(vc, animated: false, completion: nil)
