TOPIC: Automatically hide edit button when tableview is empty

Automatically hide edit button when tableview is empty 1 year, 1 month ago #1

Hi!

I was wondering if there was a way to automatically hide the edit button (left navigation bar) when the the table view is empty. Also would it be posssible to disable the "+" button when in edit/deletion mode? Below is what i did to try to achieve this but there are some cases where this approach doesn't work.

 
- (void)viewDidLoad {
	[super viewDidLoad];
 
// Instantiate the tabel model
	tableModel = [[SCArrayOfObjectsModel alloc] initWithTableView:self.tableView withViewController:self
										withEntityClassDefinition:someClassDef];
	tableModel.addButtonItem = self.navigationItem.rightBarButtonItem;	
	tableModel.autoSortSections = TRUE;
	tableModel.hideSectionHeaderTitles = TRUE;
 
if ( tableModel.sectionCount > 0) {
        self.navigationItem.leftBarButtonItem = self.editButtonItem;
        tableModel.editButtonItem = self.editButtonItem;
    }
 
}
 
- (void)tableViewModelWillBeginEditing:(SCTableViewModel *) tableViewModel
{
   tableModel.addButtonItem.enabled = NO;
}
 
- (void)tableViewModelDidEndEditing:(SCTableViewModel *) tableViewModel
{
    tableModel.addButtonItem.enabled = YES;
 
    if (tableModel.sectionCount > 0) {
 
        self.navigationItem.leftBarButtonItem = self.editButtonItem;
        tableModel.editButtonItem = self.editButtonItem;
    }
    else
    {
        self.navigationItem.leftBarButtonItem = nil;
        tableModel.editButtonItem = nil;
    }
 
}

Thanks and keep the features coming in

Hi Harold, I think we should add these as feature requests to the upcoming STV 2.1 (www.sensiblecocoa.com/forum/announcement...0-released.html#2257) Regarding your code, the tableViewModelWillBeginEditing and tableViewModelDidEndEditing delegate methods only get called when you assign your model's editButtonItem property to your bar's edit button. Hope this helps!	tarekskr OFFLINE Administrator Posts: 2402 Karma: 72
