ios - How to display a UItableView in UicollectionViewCell? -

so have collection view 3 cells, each of has tableview in it. obviously, each collection view cell has load it's table view different data table view cells.

my first thought make collection view delegate , datasrouce of table view, so, datasource need know collection view cell being loaded.

also thought of making separate class ds , delegate both collection view , table view, again, i'm stuck on how tableview ds know collection view cell it's being loaded from.

any thoughts?

edit:

after make assignment, datasource field nil. missing here?

func collectionview(_ collectionview: uicollectionview, cellforitemat indexpath: indexpath) -> uicollectionviewcell {     guard let cell = collectionview.dequeuereusablecell(withreuseidentifier: reuseidentifier, for: indexpath) else {         return uicollectionviewcell.init()     }      cell.backgroundcolor = uicolor.clear      cell.thetableview.datasource = requestedtabledatasource.init()     cell.thetableview.delegate = self      cell.thetableview.reloaddata()      return cell }  class requestedtabledatasource: nsobject, uitableviewdatasource {     func tableview(_ tableview: uitableview, numberofrowsinsection section: int) -> int {     return 16 }      func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {     guard let cell = tableview.dequeuereusablecell(withidentifier: "requestedcell") as? intervieologistrequestedcell else {         return uitableviewcell.init()     }      cell.setupcellfor(name: "dan", image: uiimage.init(named: "dan")!)      return cell } 

}

if this:

let foo = requestedtabledatasource.init()     cell.mytableview.datasource = foo 

then datasource field set, numberofrows gets called, cellforrowatindexpath doesn't.

you can set tableview.tag unique integer , identify later in delegate methods using that, recommend keeping seperate datasource/delegate each tableview, cleaner.

don't make collectionview or other view object datasource/delegate.

eg set

collectionviewcell.tableview.tag = index; collectionviewcell.tableview.delegate = commondelegate; 

or

collectionviewcell.tableview.delegate = uniquedelegate; // better choice
