title: how to show am/pm in 24 hours format in ios
body: <p>I have an application in which I let users choose their language, after choosing the language it will also change the dates and time according to the the country's date format.</p>
  
  <p>I do so by a NSDateFormatter.- [dateFormatter  setDateFormat:.....];
  for english-US - I use "h:mm a" - to show am/pm settings.</p>
  
  <p>PROBLEM IS: the am pm are only shown if my iPhone is on 12 hours mode, 
  I guess it's because it automatically checks for the iPhone's time format, 
  is there a way to override this? that the am/pm will show as well in 24 mode.</p>
