Swift - UINavigationController栏颜色不会以编程方式更改

Question

I have a problem with changing the background color of my UINavigationBar . Here's what I tried so far:

    self.navigationController?.navigationBar.translucent = true
    self.navigationController?.navigationBar.backgroundColor = UIColor.blueColor()

The navigation bar does not change. Even setting the translucency to true has no effect at all. I can change the tint color without any problems, but not the background color.

But if I change the color in the storyboard, it works fine!

Is there an option in the storyboard that I enabled/disabled by mistake? Can someone help me with this? Thanks.

Answer 1

You should set the navigation bar's barTintColor instead of backgroundColor . This should be what you are looking for.

Answer 2

self.navigationController?.navigationBar.isTranslucent = true
self.navigationController?.navigationBar.backgroundColor = UIColor.blue

This will solve it.
