I cannot seem to find this and hope it is a FAQ somewhere. How can I get the minimum NSRect needed to draw an NSAttributed string on OS X? I am doing an overlay borderless window, but I want to constrain the size based on what is needed to display the string.
How can I determine the minimum NSRect for drawing an attributed string?
