Bar button items not showing

Question

I have implemented a Detail Disclosure Button on my table view cell to edit existing texts in the cells. But the problem is that when I click on the Detail Disclosure Button it shows the existing text field but without any 'Edit' and 'Cancel' bar button items on the top. I have given the segue identifier name as 'EditItem'. I also have another segue which is named 'AddItem' that works properly and shows 'Edit' and 'Cancel' bar button item. I have checked the code many times to find out the problem but didn't find any solution. I want to know how to fix this problem.

I'm using Xcode 6 beta 6 SDK.

Your problem is that you are not adding the item the same way as you are editing the item. Look at this:

if ([segue.identifier isEqualToString:@"AddItem"]){
        UINavigationController *navigation = segue.destinationViewController;
        AddItemViewController *controller =(AddItemViewController *) navigation.topViewController;
        controller.delegate = self;
    } else if ([segue.identifier isEqualToString:@"EditItem"]){
        UINavigationController *navigation = segue.destinationViewController;
        AddItemViewController *controller = (AddItemViewController *)navigation;
        controller.delegate = self;

        //
        NSIndexPath *indexpath = [self.tableView indexPathForCell:sender];
        controller.itemToEdit = _items[indexpath.row];

    }

Notice that for the AddItem segue you are getting the view controller like this:

AddItemViewController *controller =(AddItemViewController *) navigation.topViewController;

But for the EditItem segue you are getting it like this:

AddItemViewController *controller =(AddItemViewController *) navigation;

In your storyboard, the AddItem segue is connected to a navigation controller, which is then connected to your AddViewController, but the EditItem segue goes directly to the AddViewController.

Connecting EditItem to the same navigation controller AddItem is connected to should fix your problem.
