swift – 如何在Xcode 7 OSX中创建NSRadioButton组

我正在关注如何创建单选按钮组 this tutorial。但是，似乎Radio Group在Xcode 7库中已经不再可用了，我没有找到很多关于它的信息。如何创建这样的东西：

非常感谢。

从 Xcode 7 release notes起：

The template for Radio buttons in the Interface Builder object library is Now implemented as individual NSButton objects,rather than the older NSMatrix,which is discouraged on OS X v10.8 and later. Radio buttons automatically act as a group (selecting one button will unselect all other related buttons) when they have the same superview and -action method. (16965941)

所以拖动单个单选按钮，并确保您将它们连接到同一个插座！
