cocoa - Bolding part of a string in an NSAlert -

i'm creating mac os x app , have issues formatting strings on nsalert. want informative text formatted follows :

something something something

-------something bold in middle---------

other things other things other things

so far separate lines using \n statement don't know how make line in middle bold , centred. have idea?

you should not this, , indeed cannot without subclassing nsalert, or creating generic window yourself. alert can given plain string, not include decoration information (you need nsattributedstring that); own bolding of text pass.

what can , should have @ "alerts" in hig, , see there 2 strings can supply alert: "message text", displayed in bold font, , "informative text". make use of achieve result consistent platform guidelines , needs.
