As far as I know there is no customization-based solution for this. But you can either use images for necessary segments (setImage:forSegmentAtIndex:) or look at this:
http://matteocaldari.it/2010/05/a-uisegmentedcontrol-with-custom-color(authors have subclassed UISegmentedControl & implemented custom drawing in overriden drawRect:method).
据我所知，没有基于定制的解决方案。但是您可以将图像用于必要的段 ( setImage:forSegmentAtIndex:) 或查看：http:
//matteocaldari.it/2010/05/a-uisegmentedcontrol-with-custom-color（作者已将 UISegmentedControl 子类化并在覆盖drawRect:方法中实现自定义绘图） .
