ios - selected row in custom cell doesn't pass complete data from segue to another view controller -

    - (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath{             self.data= [self.namelist objectatindex:indexpath.row];             self.data= [self.rolllist objectatindex:indexpath.row];             [self performseguewithidentifier:@"detailvc" sender:self];         } 

i've displayed student's name , roll number in custom cell. when select 1 row pass data uiviewcontroller , display in labels. i've 1 nsobject type file called 'name' , i've 1 variable called 'data' of type 'name'. here's code in didselectrowatindexpath namelist overlapped rolllist stored on same variable self.data. if rolllist line removed works good. when store rolllist in self.data overlap other.

where, self.namelist variable of type nsmutablearray contains name of student , similarly, self.rolllist contains student's roll.

below code pass data segue. here detailvc destinationviewcontroller, vc.data variable of type 'name' , self.data variable of same type.

     -(void) prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender{             if([segue.identifier isequaltostring:@"detailvc"]){                 detailvc *vc = (detailvc *) segue.destinationviewcontroller;                 vc.data = self.data;             }         } 

overlapping fundamental thing.

in case in nsobject type file (name) have add 2 variable

nsnumber *rollno; nsstring *name; 

after

-- update --

@interface tablevc : uiviewcontroller {        name *data; } -(void)viewdidload {       data = [[name alloc] init] }  -(void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath{             self.data.name = [self.namelist objectatindex:indexpath.row];             self.data.rollno = [self.rolllist objectatindex:indexpath.row];             [self performseguewithidentifier:@"detailvc" sender:self]; } 

then

-(void) prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender{             if([segue.identifier isequaltostring:@"detailvc"]){                 detailvc *vc = (detailvc *) segue.destinationviewcontroller;                 vc.data = self.data;             } } 

------ detail vc ---

@property (nonatomic, strong) name *data;   -(void)viewdidload {       self.labelrollno.text = self.data.rollno;       self.labelname.text = self.data.name; }
