try it

in cellforrowatindexpath

    [thecell.button addtarget: self                action: @selector(buttonpressed:withevent:)      forcontrolevents: uicontroleventtouchupinside]; 

then event handler this:

      - (void) buttonpressed: (id) sender withevent: (uievent *) event       {           uitouch * touch = [[event touches] anyobject];           cgpoint location = [touch locationinview: self.tableview];           nsindexpath * indexpath = [self.tableview indexpathforrowatpoint: location];             /* indexpath contains index of row containing button */          nsstring *str=[self.tableview cellforrowatindexpath:indexpath].locationcountlabel.text;             int a=[str intvalue];             a=a+1;            [self.tableview cellforrowatindexpath:indexpath].locationcountlabel.text=[nsstring stringwithformat:@"%d",a];        } 

and can done minus, same way decrease value of a.

edit

put line

         [cell.plusbutn addtarget:self action:@selector(plusbutnpressed:) forcontrolevents:uicontroleventvaluechanged]; 

in if (cell==nil) , run code not code.

    if(cell==nil)     {             [[nsbundle mainbundle] loadnibnamed:@"locationscustomcell" owner:self options:nil];             cell=locationcustomcell;             [cell.plusbutn addtarget:self action:@selector(plusbutnpressed:) forcontrolevents:uicontroleventtouchupinside]; /////////this line put here       }
