Answer 1

As you have directly joined segue from tableview, it's not proper way to do that. Instead of you have to joined segue by controller to controller. So before getting proper selected row index, your view controller push fast and you are always getting 0 index.
Instead of writing logic in prepareForSegue, you can do the same stuff in didSelect method of UITablView.
For that you have to find your destination view controller from storyboard. And set the data to required property.
EDIT
Remove your prepare segure logic and do this in didSelect
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[arrayForBool replaceObjectAtIndex:indexPath.section withObject:[NSNumber numberWithBool:NO]];
[self.tabel_view reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationAutomatic];
UIStoryboard *storyboard =
[UIStoryboard storyboardWithName:#"MainStoryboard"
bundle:[NSBundle mainBundle]];
YourDestinationVC *vc =[[storyboard instantiateViewControllerWithIdentifier:#"YourDestinationVC"]; //#"YourDestinationVC" is storyboardID for your destination view controller
vc.hello = [titles objectAtIndex:indexPath.row];
[[self navigationController] pushViewController:vc animated:YES];
}
Here is screenshot :

Answer 2

You should create your segues between viewcontrollers.
Do not create segue from cell to viewcontrollers.
Then you should call
[self performSegueWithIdentifier:#"showRecipeDetail" sender:self];
after updating the table in didSelectRowAtIndexPath

Answer 3

Try this remove prepare for prepareForSegue and in didselectrowatindexpath add.
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[arrayForBool replaceObjectAtIndex:indexPath.section withObject:[NSNumber numberWithBool:NO]];
[self.tabel_view reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationAutomatic];
member_details *destViewController = [[member_details alloc]init];
destViewController.hello = [titles objectAtIndex:indexPath.row];
[[self navigationController] pushViewController:destViewController animated:YES];
}

Answer 4

Try This
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"showRecipeDetail" sender:[YOUR_ARRAY objectAtIndex:indexPath.row]];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"showRecipeDetail"])
{
member_details *destViewController = segue.destinationViewController;
destViewController.hello = sender;
}
}
