UITableView in edit mode - 'Edit' button doesn't change status

Question

I have a UIViewController class, with a tableView. In viewDidLoad:

UIBarButtonItem *editIcon = [[[UIBarButtonItem alloc]
initWithBarButtonSystemItem: UIBarButton         


        

Answer 1

Why not use -editButtonItem of UIViewController directly ? And override -setEditing:animated: method.

// Assign the system's edit button, 
// it will change style when different edit status.
self.navigationItem.rightBarButtonItem = self.editButtonItem;

// The editButtonItem will invoke this method.
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
    [super setEditing:editing animated:animated];

    if (editing) {
         // Execute tasks for editing status
    } else {
         // Execute tasks for non-editing status.
    }
}
