自定义多点触控手势（OS X）

Question

Is it possible to create custom multi-touch gestures for OS X? I know you can now make up your own gestures through the System Preferences but my question is if it's possible for the gesture to perform an action that isn't listed in the possible Trackpad options in the OS default. For example, let's say I want to close an application by swiping with three fingers or something along those lines.

I understand that this would most likely be an outside application that would need to be written but I'm just trying to get an idea of where to start to read about this (the functions in Objective C to look at, etc.).

Thanks for the help!

是的，请覆盖touchesBegan并编写自己的自定义代码以解释相应的触摸事件。
