隐藏导航栏的分隔线，并使状态栏的颜色与导航栏的颜色相同

Question

I call

self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
self.navigationController?.navigationBar.shadowImage = UIImage() 

in viewDidLoad.

Looks like this:

The separator line below the navigation bar disappears fine. The problem is, the status bar turns white. I want it to stay the same color as the navigation bar.

if just

self.navigationController?.navigationBar.shadowImage = UIImage() 

in viewDidLoad, looks like this:

below the nav bar I have a view the exact same colour as the nav bar. I want this blended into one so it looks like the view below the nav bar is part of the nav bar.

Answer 1

It is working for me. Can u check this answer.

 self.navigationController?.navigationBar.isTranslucent = false
 self.navigationController?.navigationBar.barTintColor = UIColor.blue
 self.view.backgroundColor = UIColor.blue
 // Add your colour   

Answer 2

Your statusbar become white after you call self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default) , because your viewController.extendedLayoutIncludesOpaqueBars is NO , so when you set a opaque background image for the navigationBar, the navigationBar's background will not start from 0 but from 20 , and nothing behind the statusbar, and statusbar showing as white.

So you must call viewController.extendedLayoutIncludesOpaqueBars = YES to avoid the white statusbar.

Custom shadowImage only work if you set a custom background image for the UINavigationBar .
