A fairly standard replacement for radio buttons on iOS is a "picker". An alternative, if you have a large number of potential choices, is to use a static list under a button, and allow only one of the items to be selected and checkmarked.
iOS 上单选按钮的一个相当标准的替代品是“选择器”。如果您有大量潜在选择，另一种方法是在按钮下使用静态列表，并且只允许选择和选中其中一个项目。

Take a look at the UISegmentedControl. It functions basically as a radio button for up to ~4 options. There's no maximum limit AFAIK, but any more than 4 is somewhat difficult visually.
看一看UISegmentedControl。它的功能基本上是一个单选按钮，最多可以有 4 个选项。AFAIK 没有最大限制，但超过 4 个在视觉上有些困难。
