key/value returns nil on phone only

my code works fine on simulator. however, i'm getting error message when running on iphone 4s:

2012-04-25 12:30:24.702 design3rcgp[1812:707] *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[__nscfdictionary setobject:forkey:]: attempt insert nil value (key: cellimage)'

code:

code:

- (void)viewdidload  {      nsmutabledictionary *dictionary1 = [nsmutabledictionary dictionarywithcapacity:3];      nsmutabledictionary *dictionary2 = [nsmutabledictionary dictionarywithcapacity:3];      nsmutabledictionary *dictionary3 = [nsmutabledictionary dictionarywithcapacity:3];                [dictionary1 setobject:[[nsstring alloc] initwithstring:@"podcasts"] forkey:@"cellname"];      [dictionary1 setobject:[uiimage imagenamed:@"podcasticon"] forkey:@"cellimage"];            [dictionary2 setobject:[[nsstring alloc] initwithstring:@"briefings"] forkey:@"cellname"];      [dictionary2 setobject:[uiimage imagenamed:@"essentialicon"] forkey:@"cellimage"];            [dictionary3 setobject:[[nsstring alloc] initwithstring:@"essential updates"] forkey:@"cellname"];      [dictionary3 setobject:[uiimage imagenamed:@"eknupdicon"] forkey:@"cellimage"];            array = [[nsarray alloc] initwithobjects:                dictionary1,                dictionary2,                dictionary3,                nil];  }    - (nsinteger)numberofsectionsintableview:(uitableview *)tableview  {      return 1;  }    - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section  {      return [array count];  }    - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath  {      static temp1cell *cell;      static nsstring *cellidentifier = @"cell";            if (!cell) {          cell = [[temp1cell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:cellidentifier];      }            cell = (temp1cell*)[tableview dequeuereusablecellwithidentifier:cellidentifier];            nsdictionary *dictionary = [array objectatindex:indexpath.row];            cell.mainlabel.text = [dictionary objectforkey:@"cellname"];      cell.imageview.image = [dictionary objectforkey:@"cellimage"];            return cell;  }

this works fine on simulator. why?

 

your code failing on 1 of these lines:

code:

    [dictionary1 setobject:[uiimage imagenamed:@"podcasticon"] forkey:@"cellimage"];          [dictionary2 setobject:[uiimage imagenamed:@"essentialicon"] forkey:@"cellimage"];           [dictionary3 setobject:[uiimage imagenamed:@"eknupdicon"] forkey:@"cellimage"]; 

because you're not loading image successfully, hence trying insert nil dictionary
