This is quite a simple concept, but as of yet I have been unable to find an elegant (and calendar locale independent) solution. I need to find the first day of the month for an arbitrary NSDate. For example, given an arbitrary NSDate (arbitraryDate) another NSDate object will be returned (let's call this firstDayOfMonthDate) which repres...
