What is the default background color of the naviga

问题:

I would like to set the background color of a menu to that of the navigation bar. What is the best way to do this?

回答1:

The default navbar color in iOS 7 is [UIColor colorWithRed:(247.0f/255.0f) green:(247.0f/255.0f) blue:(247.0f/255.0f) alpha:1];

回答2:

To get the tint color of a navigation bar, do this:

[aNavbar barTintColor]

By using this when you set the background color of your menu, you will not have to change it in case you change your navigation bar tint.

In Swift, it is:

UIColor(colorLiteralRed: (247/255), green: (247/255), blue: (247/255), alpha: 1)

I am not sure the color does not change from version to version. In my app I use this:

var navBarDefalutColor: UIColor?

// save:
navBarDefalutColor = self.navigationController?.navigationBar.tintColor

//restore:
self.navigationController?.navigationBar.tintColor = navBarDefalutColor!

Swift 3.0 +

UIColor(red: (247/255), green: (247/255), blue: (247/255), alpha: 1)

You can set the barTintColor to nil to restore to the default white color.
