How to determine if an NSButton is a checkbox?

Question

In Interface Builder you can set the style of a button to "Check" to turn it into a checkbox, and you can set the style of a button in code using NSButton's setButtonStyle: method, but how can I determine at runtime whether a particular NSButton is a checkbox (or radio button, or regular push button, etc)?

Part of the project I am working on requires loading views from other bundles and there is special behaviour required for each checkbox (these bundles are from 3rd parties).

I'm not sure there's a foolproof way to do this. You can check the bezelStyle, and for a checkbox that logs 2 (NSRegularSquareBezelStyle). I don't know if there are other buttons that have the NSRegularSquareBezelStyle, that are not check boxes. You'll probably have to experiment to find this out.

After Edit : I did find one other button that logs 2 for bezelStyle (the bevel button), but you can log [button.cell showsStateBy], and the check box was the only one I found that logs 1.
