ios - Custom UITableViewCell, GetCell throws UnknownNSKeyException -

i have created custom uitableviewcontroller, cell , source in project. controller , cell created iphone uiviewcontroller template got partial class paired xib file. have same setup working table , have followed same process (i think) create 1 why have no idea why i'm getting error.

this getcell in tableviewsource class

public override uitableviewcell getcell (uitableview tv, nsindexpath path) {     mycell ocell;     nsarray oviews;     //     ocell = tv.dequeuereusablecell ("mycell") mycell;     //     if (ocell == null)     {         oviews = nsbundle.mainbundle.loadnib ("mycell", tv, null);         ocell = runtime.getnsobject (oviews.valueat (0)) mycell;     }     //     ocell.updatewithdata (mydatacollection[path.row]);     //     return ocell; } 

i exception on line tries load nib:

objective-c exception thrown. name: nsunknownkeyexception reason: [ setvalue:forunidentifiedkey:]: class not key value coding-compliant key lbl_address.

i'm thinking refers problem in ib have created cell interface lbl_address uilabel inside uitableviewcell. i'm trying play around things in ib can pretty infuriating if don't correctly first time round. recognise error , set me straight.

edit

in absence of finding answer have chosen avoid loading nib , have made following changes code:

new get cell method in mytableviewsource

public override uitableviewcell getcell (uitableview tv, nsindexpath path) {     mycell ocell;     //     ocell = tv.dequeuereusablecell ("mycell") mycell;     //     if (ocell == null)         ocell = new mycell ("mycell");     //     ocell.updatewithdata (mydatacollection[path.row]);     //     return ocell; } 

new constructor mycell

public mycell (string sidentifier)     : base (uitableviewcellstyle.default, sidentifier) {     // set contents of cell in absence of loading nib     txt_name = new uilabel ()     {         font = uifont.systemfontofsize (15),         textcolor = uicolor.lightgray     };     img_profile = new uiimageview ();     //     // make sure add controls content view!     contentview.add (txt_name);     contentview.add (img_profile); } 

hope helps out there :)

this due element has been removed previous connection outlet in xib still remains valid.

i try following steps.

open xib. right click on cell. if see yellow warning near key name, remove (x button).

let me know if fix problem.
