我知道有一个 UISlider 但有人已经制作了 RangeSlider (用两个拇指吗?) 或者知道如何扩展 uislider?

我不认为你可以直接扩展 UISlider,你可能需要扩展 UIControl。
无论如何,这就是我所做的并创建了这个: http://github.com/doukasd/DoubleSlider
看一下,如果您觉得有用,请告诉我。您可能还想看看我的博客文章,其中包含一个展示其工作原理的视频(以确保我们谈论的是同一件事):http://dev.doukasd.com/2010/08/double-slider/
I don't think you can directly extend UISlider, you probably need to extend UIControl.
Anyway, this is what I did and created this: http://github.com/doukasd/DoubleSlider
Have a look and let me know if you find it useful. You might also want to have a look at my blog post which includes a video showing how it works (to make sure we are talking about the same thing): http://dev.doukasd.com/2010/08/double-slider/
