cocoa - UIKit's [NSString sizeWithFont:constrainedToSize:] in AppKit -

is there equivalent method in appkit (for cocoa on mac os x) same thing uikit's [nsstring sizewithfont:constrainedtosize:]?

if not, how go getting amount of space needed render particular string constrained width/height?

update: below snippet of code i'm using expect produce results i'm after.

nsdictionary *attributes = [nsdictionary dictionarywithobjectsandkeys:                             [nsfont systemfontofsize: [nsfont smallsystemfontsize]], nsfontattributename,                             [nsparagraphstyle defaultparagraphstyle], nsparagraphstyleattributename,                             nil]; nssize size = nsmakesize(200.0, maxfloat); nsrect bounds;  bounds = [@"this really really really long string won't fit on 1 line"              boundingrectwithsize: size              options: nsstringdrawingusesfontleading              attributes: attributes];  nslog(@"height: %02f, width: %02f", bounds.size.height, bounds.size.width); 

i expect output width 200 , height greater height of single line, produces:

height: 14.000000, width: 466.619141 

thanks!

edit: should able things normal way in lion , later. problems described below have been fixed.

there no way accurately measure text among current mac os x apis.

there several apis promise work don't. that's 1 of them; core text's function purpose another. methods return results close wrong; return results seem mean nothing @ all. haven't filed bugs on these yet, when do, i'll edit radar numbers answer. should file bug well, , include code in small sample project.

[apparently have already filed core text one: 8666756. it's closed duplicate of unspecified other bug. cocoa, filed 9022238 method dave suggested, , file 2 nslayoutmanager bugs tomorrow.]

this closest solution i've found.
