Push a new view controller with navigation controller

Question

So I created a new view controller which has the Custom class named DescriptionViewController . And from my current view controller inside didSelectRowAtIndexPath I use this code:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

    DescriptionViewController *descriptionViewController = [[DescriptionViewController alloc] initWithNibName:@"DescriptionViewController" bundle:nil];
    [self.navigationController pushViewController:descriptionViewController animated:YES];
}

But nothing happens when I click on a cell. Is there anything more I need to do ?

Answer 1

If you put in a breakpoint and it is stopping in the didSelectRowAtIndexPath, my guess is that your self.navigationController is nil.

If you are using storyboards, make sure your entry point is a UINavigationController and not a UIViewController.

If you loading this view controller though a modal transition, make sure you push on a navigation controller with this view controller as the root view instead.

在情节提要中选择您的ViewController，然后在顶部转到editor-> embed in-> navigation controller，然后代替initWithNibName尝试尝试init
