I'm trying to convert it to...
I hope you'll excuse the seemingly broad nature of this question, but it gets quite specific. I'm building a document-based Cocoa application that works like most others except that I am using SQLCipher for my data store (a variant of SQLite), because you don't get to set your own persistent data store in Core Data, and also I really ne...

Hello, I can set background color for NSTextView, also insertion color, but when I try to change text color it just doesn't work.
