编辑栏按钮无法正常工作

Question

In my table view controller's viewDidLoad: method I have the standard line self.navigationItem.leftBarButtonItem = self.editBarButtonItem() to add the Edit bar button.

When my table view controller is a subclass of UITableViewController (and thus has the table view as its view property), the Edit button works normally and triggers a change of table view's editing state.

But after I had rewritten my table view controller so it now subclasses UIViewController (implementing UITableViewDataSource and UITableViewDelegate protocols), the Edit button has stopped working. It still switches between Edit and Done, but no longer changes table view's editing state.

How to fix that? Should I implement setEditing: animated: method in my view controller? If yes, could you post some sample code?

Answer 1

It was simple. I just had to call super and update table view's editing state.

override func setEditing(editing: Bool, animated: Bool) {

    super.setEditing(editing, animated: animated)
    tableView.setEditing(editing, animated: animated)
}
