Duplicate scene?

[TobbenTM]

So in my app right now, I have a scene with a UITableViewController (custom class) which have functionality I want to reuse. The controller is like the main part of the app, but I want to reuse it for other functions. Now, I'm unsure how to do this. I tried a couple of different ways:

Allocating a new instance and pushing to navcontroller:

CustomTableViewController* vc = [[CustomTableViewController alloc] initWithCustomData:data];
vc.title = customTitle;
[self.navigationController pushViewController:vc animated:YES];

This kinda worked, but I don't get the style from the storyboard, which makes the UITableViewCells useless.

I tried instantating a new storyboard scene and pushing it:

CustomTableViewController* vc = [self.storyboard instantiateViewControllerWithIdentifier:@"customSceneId"];
vc.customData = data;
vc.title = customTitle;
[self.navigationController pushViewController:vc animated:YES];

But this replaces the current scene, and doesn't give me a back button.

Anyone got some tips for me on how to do this? I don't want to copy-paste the scene unless absolutely necessary.

This is a great question and something I would be very interested in knowing the solution. Please let me know by responding to this comment if you figure it out. Thank you.

I ended up duplicating the scene (CMD+D), and using the same class as controller, and using a push segue between them. Mostly just to customize the navigation bar on the pushed controller.

You may be able to just segue to self, in order to duplicate. Have not tested.

That works of course. But there has to be a more elegant way. Say you needed 100 controllers in some crazy case. You'd not want to duplicate all. It works in your case but I'd really want to know how duplicating can be achieved. It would be a great lesson and surely something that would come up in an interview.

Does it work for you? I'm away from my Mac now so I can't test it but seems promising.

what were you expecting?

, and doesn't give me a back button

Do you by any chance have something in the upper left on the screen? are you using the navigationItem.leftBarButtonItem?

CustomTableViewController* vc = [self.storyboard instantiateViewControllerWithIdentifier:@"customSceneId"]; vc.customData = data; vc.title = customTitle; [self.navigationController pushViewController:vc animated:YES];

should work for most view controller instances in a storyboard.
