TableView first cell hidden under search bar when returning to view

Question

I have some weird behaviour on a TableView and hope someone could help me out.

I have a TableView with a searchbar in the navigation. The cells lead to a detail view. Whenever I search in the TableView and then hit a result cell to go to the detail view, on returning from the detail view to the TableView the first cell disappears underneath the opened search bar.

Searching:

On selecting the item (detail view) and then returning (using the nav bar) the first cell is hidden under the search bar:

Some things to note:

If I print the contentInset on returning it gives -44 (1 cell hidden, like in the pic). I'm unable to set the contentInset back to 0.0 (or anything else for that matter) as it doesn't seem to change anything.

tableView.setContentOffset(CGPoint(x: 0, y: 0), animated: true) print(tableView.contentOffset.y) // -44.0

If the first cell is hidden and I hide the search bar by pushing the table down and then up again, the problem automatically disappears and the ContentInset restores to 0.0.

UPDATE: I found that the view restores itself as well after returning the app from the background:

I can't however reproduce that in code. I've tried:

view.setNeedsLayout() view.layoutIfNeeded() tableView.reloadData()

I guess it is because of scrollview insets. Checkout this answer stackoverflow.com/questions/24335497/… — Rahul

There are other ways to solve it but above seems simplest one. — Rahul

How have you implemented your tableView? Are you using a UITableViewController or manually adding a UITableView? — RichAppz

@Rahul: that doesn't seem to be the same issue as mine. I already tried toggling the automaticallyAdjustsScrollViewInsets. — Tum

@RichAppz UITableViewController. I add the search bar programmatically in the viewDidLoad. I have the same implementation in other views as well where it doesn't have the same error, maybe it's the detail view that's causing it. — Tum

Solved, I set searchController.hidesNavigationBarDuringPresentation = false, which caused the bug. See the answer on this post: Search Bar in a Navigation Item collapses and gets stuck under status bar upon navigation pop, on iOS 11.

Thanks for the help!

Put dismiss(animated: true) in tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
