objective c - NSTableView cells are not getting data from the delegate method -

i working on simple tableview , stumped here. table view cells not getting data tableview:objectvaluefortablecolumn:row: method.

i supposed this:

but getting this:

here .h , .m files of tablecontroller class

@interface tablecontroller : nsobject <nstableviewdatasource, nstableviewdelegate>  @property (nonatomic, strong) nsarray *numbers; @property (nonatomic, strong) nsarray *numbercodes;  @end 

and

#import "tablecontroller.h"  @implementation tablecontroller  #pragma mark - custom initialisers  - (nsarray *)numbers {      if (!_numbers) {         _numbers = @[@"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"10"];     }     return _numbers; }  - (nsarray *)numbercodes {      if (!_numbercodes) {         _numbercodes = @[@"one", @"two", @"three", @"four", @"five", @"six", @"seven", @"eight", @"nine", @"ten"];     }     return _numbercodes; }  -(nsinteger) numberofrowsintableview:(nstableview *)tableview{     nslog(@"what ho tally!");     return self.numbers.count; }  -(id) tableview:(nstableview *)tableview objectvaluefortablecolumn:(nstablecolumn *)tablecolumn row:(nsinteger)row{     if ([tablecolumn.identifier isequaltostring:@"numbers"]) {         nslog(@"%@", [self.numbers objectatindex:row]);          // first colum (numbers)         return [self.numbers objectatindex:row];       } else {         nslog(@"%@", [self.numbercodes objectatindex:row]);         // second column (numbercodes)         return [self.numbercodes objectatindex:row];      } }  @end 

the objects in array getting nslogged properly. somehow not getting reflected in tableview.

thew following may further give more info...

i think need use tableview:setobjectvalue:fortablecolumn:row: instead of -(id) tableview:(nstableview *)tableview objectvaluefortablecolumn:(nstablecolumn *)tablecolumn row:(nsinteger)row{, no ?

edit :

in fact, in project, need set table view "cell based" content mode instead of "view based" mode , works !
