How do I convince the NSTextView that the text starts at the bottom?

I will add some lines to NSTextView

, but I want them to start at the bottom. The new added line must be below the last added line.

It can be installed in Java or C # VerticalAligment = bottom

, but I can't seem to find a suitable way to achieve this in Cocoa ... Any thoughts?

EDIT: I guess I didn't elaborate on what exactly I want, so I'll add two photos. First this is what it looks like now, the second is what I want. Basically, the newest line is always at the bottom, and the oldest ones are always at the top. Does it make sense now?
