tableView.tableHeaderView returning ni

[mhlangagc]

I have a tableHeaderView in my UITableViewController that displays some data pulled from Parse. On trying to used this function I get a nil value returned and a crash. Removing it allows the app to run without crashing but does not show the background view setup when the cells are empty. Anything I could be missing?

func verticalOffsetForEmptyDataSet(scrollView: UIScrollView!) -> CGFloat {


        return -tableView.tableHeaderView!.frame.size.height/2.0


}

Well, you should not force unwrap. Use a let guard or if let and the exception should go away. Maybe this callback es called to early, before your tableHeaderView is initialised. Try that out first.

-tableView.tableHeaderView!.frame.size.height/2.0 is fit to top tableView?
