Large title UINavigationbar bottom line flickers on scroll

Question

I have a view controller with a tableview in it. Pulling down on the tableview expands the navigationbar as expected but the bottom hair line flickers. Has anyone faced this problem before?

Answer 1

The easiest possible solution will be simply set self.tableView.separatorColor = UIColor.clear & add a label(identical to seprator line)inside your tableview cell or header.

Answer 2

If you are using storyboard and have a embedded UINavigationController then just un-check Translucent property from attribute inspector.

self.navigationController?.navigationBar.isTranslucent = false

Answer 3

1. Please check that your UITableView's content (cells, header) are clipped to bounds.
2. The issue may be with shadows, if you use them. (Can not tell for sure)

Answer 4

Find the source of the dark gray color and change it to UIColor.clear

I would guess it's the background color of the top UIView and as it expands and contracts its size, there's a 0.5px delay every few pixels.

It's hard to tell without seeing your code.

Answer 5

removing navigationBar.barTintColor custom color, fix in my app (pay attention, do not set barTintColor to .clear, don't custom tintColor)
