推荐答案

iPhone应用程序没有单选按钮。 类似iPhone的方法是使用选择器视图，或者在分组表视图中使用检查附件在选定行上显示多行。

iPhone apps do not have radio buttons. The "iPhone-like" way to do this is either by using a picker view or by having several rows in a grouped table view with a check accessory on the chosen row.

如果由于某种原因你真的觉得需要有单选按钮，请使用带有自定义按钮类型的UIButton。将空心圆设置为正常控制状态的图像，将实心圆圈设置为选定状态的图像。

If for some reason you really, really feel the need to have radio buttons, use a UIButton with a button type of custom. Set the empty circle as the image for the "normal" control state and the filled circle as the image for the "selected" state.
