提问by Kris Roofe
I want to set colors for the text and background of UISegmentedControl. So I've four colors to set, the default and selected color of the text and background.
我想为 UISegmentedControl 的文本和背景设置颜色。所以我有四种颜色要设置，文本和背景的默认颜色和选定颜色。
I can use tintColorand backgroundColorto set the background. But how to set the default text color, not same as the tint color?
我可以使用tintColor和backgroundColor来设置背景。但是如何设置默认文本颜色，与色调颜色不同？
Note: here is swift3 not the older language. I'm a beginner of ios, I just start from the swift3, have no experience of the former language.
注意：这里是 swift3 而不是旧语言。我是ios的初学者，我刚从swift3开始，对以前的语言没有经验。
Any help will be appreciated.

//selected background color
customSC.tintColor = UIColor(red:65/255.0, green:140/255.0, blue:218/255.0, alpha: 1.0)
//selected title text color
customSC.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.white], for: UIControlState.selected)
