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.

I am not sure the color does not change from version to version. In my app I use this:
var navBarDefaultColor: UIColor?
// save:
navBarDefaultColor = self.navigationController?.navigationBar.tintColor
//restore:
self.navigationController?.navigationBar.tintColor = navBarDefaultColor!

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