title: NSDateformatter setDateFormat according to currentLocale
body: <p>I'm going mad with, probably, a stupid problem.</p>
  
  <p>I have 3 strings: year, month and day. I need to have a date in the right format based on currentLocale, so i.e. if currentLocale localeIdentifier is en_US my dateFormat should be:
  MMM/dd/yyyy</p>
  
  <p>if it's fr_FR the dateFormat should be dd/MMM/yyyy</p>
  
  <p>I don't think the only way to do this is to get currentLocale localeIdentifier and start with a bunch of if then.</p>
  
  <p>Thanks in advance.</p>
