How to enable/disable scrolling in UITableView?

Question

I know about this command:

self.tableView.scrollEnabled = true

The question is: I want to lock scrolling according to the scrollView position. For this I do:

let topEdge = scrollView.contentOffset.y
    let followersViewEdge = CGRectGetHeight(self.profileView.frame) - 50

    if topEdge >= followersViewEdge {
        self.tableView.scrollEnabled = true
    }

it works, but the problem is that it does not lock or unlock the scrolling immediately. For locking or unlocking the UITableView scrolling I need to release my finger from the screen and scroll again. In this case it works.

I want to make it immediately, so it locks and unlocks the scrolling while I'm swiping on the screen. How can I do it?

UPDATE

My code works. It's not a problem. Problem is that I need to make these changes immediately, without releasing my finger from the screen.

So, do not answer me how to lock scrolling! I know how to do this.
