My edit button is placed in viewDidLoad:

self.navigationItem.rightBarButtonItem = self.editButtonItem;

It shows up correctly on the nav bar, and tapping this button indeed change it to Done. However, no minus buttons show up in my table rows. Swiping a row, then tap Delete works, though.

Any ideas?

EDIT 1: Here's how I'm doing:

- (void)loadView {
tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
tableView.delegate = self;
tableView.dataSource = self;
tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

self.view = tableView;
}

EDIT 2: My observation is that the edit and minus buttons display fine if my tableview is created in IB (RootViewController). The other two (or three) tableview are created by the aforemention code, so that might be the problem. Guess I'd have to dive in to isEditing, editing and whatnot.
