Question

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *__strong)indexPath
{


    TestViewController*detail = [self.storyboard instantiateViewControllerWithIdentifier:@"TestView"];


    [self.navigationController pushViewController:detail animated: YES];

    detail.outputLabel.text =[NSString stringWithFormat:[mutablearray1 objectAtIndex:indexPath.row]];
      // detail.outputImage.image =[NSString stringWithFormat:[mutablearray2 objectAtIndex:indexPath.row]];  
}
@end

Using above code i displayed text in tableview cell to detail view.

I also want to display image corresponding to each row in detail view. Problem lies in the commented part i know.

What modification is needed?

when uncomment i got the error: Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘-[NSConcreteData getCharacters:range:]: unrecognized selector sent to instance

Answer 1

I assume outputImage is an UIImageView object.
I seems you are setting NSString object instead of UIImage object. Please check.
