There are many questions like mine both in Objective-c and Swift that ask how to lock a UIToolbar to the top of a UITableViewController, and I will add to that list. However, my question is unanswered by the others. I need to lock it to the top of the view controller so that it is not considered a cell by the program, and so it doesn't move down, but is locked at the top instead.
All other answers that I found want me to either
(a) Embed the UITableViewController in a UINavigationViewController
or
(b) To use a UIViewController with a UITableView inside it
I do not want to do either one of these.
I want to keep a UITableViewController––not to replace it with a UIViewController and UITableView––and I do not want to use a UINavigationViewController––I am trying to not do that because it causes a plethora of issues in the rest of the app (which can be fixed but I don't want to have to do that).
