objective c - Unrecognized selector sent to instance and crash in main.m in iOS application -


hi cannot understand i'm searching help. here is... i'm working on storyboard ios , during prepareforsegue method trying set property of viewcontroller loaded.

right here crash pointing @ center line of main.m , here message:

*** terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[uitableviewcontroller setdetails:]: unrecognized selector sent instance 0x8880b80'

here method prepareforsegue ended looking mistakes following exception:

- (void) prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender { if ([[segue identifier] isequaltostring: @"cellsegue"])   {     apptestdetailviewcontroller *detailviewcontroller = [segue destinationviewcontroller];     nsindexpath *indexpath = [self.tableview indexpathforselectedrow];     detailviewcontroller.details = self.detailslist[indexpath.row];   } }

well.. self.detailslist nothing array of details items. details property declared in apptestdetailviewcontroller.h this

#import <uikit/uikit.h> #import "details.h" #import "detailcell.h"   @interface apptestdetailviewcontroller : uitableviewcontroller  @property (strong, nonatomic) details *details;  @end

so... can't understand problem setting property. i'm missing something... hope clear , lot help!

the error message

-[uitableviewcontroller setdetails:]: unrecognized selector ...

shows detailviewcontroller not instance of apptestdetailviewcontroller expect, "only" uitableviewcontroller.

one possible reason did not set "custom class" controller in storyboard file.
