import uikit  class rootviewcontroller: uitableviewcontroller, uitableviewdatasource,     uitableviewdelegate { private var cellpointsize: cgfloat! private var albumslist: albumlist! private var albums:[album]! private let albumcell = "album"  @iboutlet var mytableview: uitableview! override func viewdidload() {     super.viewdidload()      let preferredtableviewfont = uifont.preferredfontfortextstyle(uifonttextstyleheadline)     cellpointsize = preferredtableviewfont.pointsize     albumslist = albumlist.sharedalbumlist     albums = albumslist.albums     self.mytableview.datasource = self     self.mytableview.delegate = self  }  override func viewwillappear(animated: bool) {     super.viewwillappear(animated)     tableview.reloaddata() }  // mark: - table view data source  override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {     // return number of rows in section.     return albums.count }  override func tableview(tableview: uitableview, titleforheaderinsection section: int) -> string? {     return "albums" }  override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {          let cell = mytableview.dequeuereusablecellwithidentifier(albumcell, forindexpath: indexpath) as! uitableviewcell         //cell.textlabel?.font = fontfordisplay(atindexpath: indexpath)         cell.textlabel?.text = albums[indexpath.row].name         cell.detailtextlabel?.text = albums[indexpath.row].artist         return cell        }  @ibaction func addnewalbumaction(sender: uibarbuttonitem) {     var newalbum = album(namein: "new title", yearin: "new year", artistin: "new artist", labelin: "new label")     albumslist.addalbum(newalbum)     dispatch_async(dispatch_get_main_queue(), { () -> void in         self.mytableview.reloaddata()     }) }  func savedata(albumobject: album) {     var archivearray = nsmutablearray(capacity: albums.count)     in albums {         var albumencodedobject = nskeyedarchiver.archiveddatawithrootobject(a)         archivearray.addobject(albumencodedobject)     }      var userdata = nsuserdefaults()     userdata.setobject(archivearray, forkey: "albums")     userdata.synchronize() }

my albums array adding data correctly. can see albums in debugger. delegate methods never being called after first time when app loads. ideas?

in tableview:numberofrowsinsection:, returns albums.count

but when button pressed, add new album albumslist

the problem is, albums not update.

so think should return albumslist.albums.count instead.

and in tableview:cellforrowatindexpath:, modify cell correspond albumslist.albums[indexpath.row]
