Thank you all for your responses. I need to support 10.6.8, so in end I chose two different approaches for the textview and pdfview.
For the textview, I handle drawing a thin rect around the textview's bounds when it is first responder. I just handle the change in -becomeFirstResponder and -resignFirstResponder. For the pdfview, I embedded it in an NSView which receives notifications when the pdfview becomes or resigns first responder. Then it draws a thin rect around its bounds. The pdfview is then 1 pixel smaller on all sides that this container view. I'm not really happy with either of these solutions, but nothing else seemed to work so far. The end result is visually not too bad. The thing I like least is that I need this 1 pixel gap in the container view for the pdfview. Because when the pdfview doesn't have focus, I have to decide to draw something there. For now I toggle between stroke colors (dark grey and focus ring color).
