How can I get the color and translucency of the iOS 10 watch Navigation Bar?

问题

I am looking to get the translucency and color of the iOS 10 watch navigation bar. I managed the color by color picking the RGB but I cannot figure out the translucency. I am using Swift 3, can anyone tell me how to get the translucency? I have circled what translucency I'm looking for.

Please provide the code if you can.

Use below method to achieve navigationBar translucent effect. When UIContentView scrolls as the picture you posted.

In viewDidLoad:

  view.backgroundColor = UIColor.black
  navigationController?.navigationBar.barStyle = UIBarStyle.blackTranslucent
  navigationController?.navigationBar.tintColor = UIColor.white

Updated

Output:

Note:

• Screen recording is not showing the real result.I recommend you to test the code in a real device.

• You can use the same method. If you developing tabBar based project.

If you mean you want to get rid of translucent effect, just

Programatically:

navigationController?.navigationBar.isTranslucent = false

In Storyboard:

Just click on the navigation bar, and in attribute inspector, you'll find it.
