You need to override NSButtonCell. You'll use drawInteriorWithFrame:inView: or a simililar method to do your custom drawing. If you've never used custom cells before it can be a bit of a learning experience, but there's a lot of good advice out there, like this page to start with.
您需要覆盖NSButtonCell。您将使用drawInteriorWithFrame:inView:或一个相似的方法来进行自定义绘图。如果你从来没有使用过自定义单元格,那么它可以是一种学习经验,但是那里有很多好的建议,就像这个页面一样。
You could also take a look at an open source framework like BGHUDAppKit for an example.

As a sidenote, if the only thing you need to do is change the 'check' image from the default one provided by Apple, then go to the properties of the NSButton in XCode/Interface Builder and select an Image and an Alternate Image. Same thing goes for radio buttons.
作为旁注,如果您需要做的唯一事情就是从Apple提供的默认图像中更改“检查”图像,然后转到XCode / Interface Builder中的NSButton属性并选择图像和备用图像。单选按钮也是如此。
