1)创建UISegmentedControl的自定义类，并在 awakeFromNib

推荐答案
根据我对您问题的理解，您希望更改与UISegmentControl着色颜色相同的背景颜色.您只需要使用以下内容即可:
From my understanding of your question, you want to change the background color same as UISegmentControl tint color. What you need to do is simply use this:
label.backgroundColor = segmentedControl.tintColor;
希望这可以帮助您，如果不尝试的话:
Hope this will help you if not try this:
您只需要提供其背景颜色即可从情节提要中清除.这是由于默认的背景选择和默认选择是根据主题而发生的.将segmentControl的背景色设置为清除后，您将获得所需的结果.
You just need to give its background color to clear from storyboard. This is happening due to default background selection and default selection is as per theme. Once you set the segmentControl background color to clear you will get the required result.
或者您可以执行以下操作:尝试将您的UISegmentcontrol背景颜色设置为在viewDidLoad中清除，您将获得结果.我已经尝试过了，并且对我有用.
Or you can do: Try to set your UISegmentcontrol background color to clear in viewDidLoad, you will get your result. I have tried this and it worked for me.
segment.backgroundColor = Color.clear;
