When adding nil to tableHeaderView cant show it again

I have added table Header in the TableView in Storyboard, I want to hide/show this header.

I have a segmented control, and want the header to show in one of the segments.

To hide the header in one segment I used: tableView.tableHeaderView = nil and this hides it. In other segments, to unhide the header I used: 

if tableView.tableHeaderView == nil {
    tableView.tableHeaderView = self.tableViewHeader
}

but the header does not shown again. How to solve this?

Solution

  • If you set 

    tableView.tableHeaderView == nil

    Than You create a local variable to store tableView.tableHeaderView on viewDidLoad as this 

    self.tableViewHeader = tableView.tableHeaderView

    than check

    if tableView.tableHeaderView == nil 
{
 tableView.tableHeaderView = self.tableViewHeader
}
