Question

When i click on row to navigate to the other view it give me crash

"Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<detailInfo 0x6b503d0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key lblText.'
*** First throw call stack:
"

This is my code :

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{   
    _vcontroler = [ urls objectAtIndex:indexPath.row];

    if (!self.detailViewController)
    {
         self.detailViewController = [[[detailInfo alloc] initWithNibName:@"detailInfo" bundle:nil] autorelease];

    }
      detailViewController.vcontroler =_vcontroler; 

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

    [detailViewController release];
}

The problem is that you removed an graphical object from view’s frame without removing outlet connection. Select your view controller’s .xib, then select File's Owner (left click on it) and remove outlet connection for lblText object. Build & run. It should be fine.
