Change background color of uisearchcontroller

Question

How does one change the background colour of the uisearchcontroller? Atm it looks like this

I want it all one colour. I've attempted sc.view.tintColor = UIColor.rgb(10, green: 150, blue: 255) and sc.view.backgroundColor = UIColor.rgb(10, green: 150, blue: 255) but doesn't remove the grey bit the side

Answer 1

Eh, with some thought I solved it.

sc.searchBar.barTintColor = UIColor.rgb(10, green: 150, blue: 255)

Answer 2

     sc.searchBar.searchBarStyle = UISearchBarStyleProminent
     sc.searchBar.backgroundImage = [UIImage new]
     sc.searchBar.barTintColor = UIColor.rgb(10, green: 150, blue: 255)

set searchBarStyle to Prominent. It working for me
