更改 NSTextView 默认顶部标尺的背景颜色
默认情况下，如果您将 NSTextView 添加到应用程序并转到“格式”->“文字->显示标尺，标尺将显示在文本视图的顶部，就像在 TextEdit 中一样，具有各种格式选项，并且看起来像这样：
我将如何更改该标尺的背景颜色？ （标尺也应该在 10.6 上出现，甚至可能更早）
感谢您的任何提示/建议！
编辑一个：在稍微了解了标尺上对description的调用及其子视图是什么之后，我得到了这些结果：
Description of ruler: <NSRulerView: 0x10056e580>
Orientation: horizontal, Rule thickness: 16.0
Flipped: Yes, frame: {{0.0, 0.0}, {528.0, 55.0}}, bounds: {{0.0, 0.0}, {528.0, 55.0}}
Accessory frame: {{0.0, 0.0}, {528.0, 24.0}}
Ruler's Subviews: (
"<NSStopTouchingMeBox: 0x10059b940>"
)
这是一个非常有趣的类名，是不是吗？ =P
By default, if you add a NSTextView to an application and go to Format -> Text -> Show Ruler, a ruler will be shown on top of the text view like in TextEdit with various formatting options, and will look like so:
How would I go about changing the background colour of that ruler? (The ruler should also be there on 10.6, maybe even earlier)
Thanks for any hints/suggestions!
EDIT ONE: After stabbing around a bit what a call to description on the ruler and what it's subviews are, I came to these results:
Description of ruler: <NSRulerView: 0x10056e580>
Orientation: horizontal, Rule thickness: 16.0
Flipped: Yes, frame: {{0.0, 0.0}, {528.0, 55.0}}, bounds: {{0.0, 0.0}, {528.0, 55.0}}
Accessory frame: {{0.0, 0.0}, {528.0, 24.0}}
Ruler's Subviews: (
"<NSStopTouchingMeBox: 0x10059b940>"
)
That's a pretty interesting class name, isn't it? =P

我会尝试子类 NSRulerView。您可以覆盖drawRect：方法并用您的颜色填充矩形。
I would try to subclass NSRulerView. You could overwrite the drawRect: method and fill the rect with your color.
