NSAttributedString default color/font etc

问题

I'm using drawGlyphsForGlyphRange to render an NSAttributedString (in NSView drawRect)

Is there any way to default the color/font etc of an NSAttributedString? Clearly I could set those values specifically for a given range - but that will then override any specific settings in the string. Got the feeling I have a fundamental misunderstanding of how NSAttributedStrings should be used!!

Thanks

回答1:

The default font for NSAttributedString objects is Helvetica 12-point on iOS and Lucida Grande (or whatever the default system font is set to) on OS X. Use initWithString:attributes: to create an NSAttributedString with some pre-set attributes that would initially apply to the whole string. Any attributes you will set to different ranges of your string afterwards will supplement/replace the attributes you define when you create your instance of NSAttributedString.
