I want to prevent users from making the same selection twice or more and just pushing and pushing the same view controller onto the stack
Try…
Create BOOL value, something like
BOOL isSelectionActive;
Then in –
(void)tableView:(UITableView
*)tableView didSelectRowAtIndexPath:(NSIndexPath
*)indexPath set the isSelectionActive=TRUE;-
Then, in – (NSIndexPath
*)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath
*)indexPath return nil if isSelectionActive is TRUE, otherwise
return the indexPath.
Before dismissing the pushed view.
set isSelectionActive=False. You can
do this by passing in a reference to
the viewController that is pushing
the new view. And setting isSelectionActive=FALSE before dismissing the view.
or
in viewWillAppear, which will get
called when you dismiss the pushed
view.
