如何检查OSX与可可API的滚动方向 [英] How to check scrolling direction of OSX with cocoa APIs

问题描述

我无法找出滚动是否设置为倒转模式或当前没有..我想显示该设置，也用于滑块和东西。

I can't find out if scrolling is set to reverse mode or not currently.. and I want to show that setting and also use this for sliders and stuff.

我知道我可以检查只检查plist：

I know I can check just check the plist :

dict = open("/Library/Preferences/.GlobalPreferences.plist");
=> dict.objectForKey("com.apple.swipescrolldirection");

我在这里寻找任何API？ / p>
