The indexPath of custom table cell is undefined, objective c -

i have created custom cell call pendingdoctortableviewcell , used in pendingdoctortableview. work find , added disclosure indicator using

[cell setaccessorytype:uitableviewcellaccessorydetaildisclosurebutton]; 

it's able performed segue "showpendingdoctor".

however when used prepareforsegue, indexpath undefined.

- (void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender {        if ([segue.identifier isequaltostring:@"showpendingdoctor"]) {         nsindexpath *indexpath = [self.tableview indexpathforselectedrow];         actionforpendingdoctorviewcontroller *destviewcontroller = segue.destinationviewcontroller;         destviewcontroller.myobjects = [myobject objectatindex:indexpath.row];          // hide bottom tab bar in detail view         //   destviewcontroller.hidesbottombarwhenpushed = yes;     } } 

how can know row had been tap. because return object of 1st index.

anyone can me? i'm rushing project. thanks.

declare variable of nsindexpath save selected indexpath

nsindexpath *selectedindexpath; 

use tableview delegate identify selected row , perform segue programmatically

-(void)tableview:(uitableview *)tableview didselectrowatindexpath:    (nsindexpath *)indexpath  {    [self performseguewithidentifier:your_segue_identifier sender:self];  } 

pass object next viewcontroller through prepareforsegue

-(void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender  {    if ([segue.identifier isequaltostring:your_segue_identifier])     {       actionforpendingdoctorviewcontroller *destviewcontroller =    segue.destinationviewcontroller;       destviewcontroller.myobjects = [myobject objectatindex:selectedindexpath.row];    }  }
