  1. They are called format specifiers, could also be called ‘placeholders in a string for the variables that will follow’.

  2. They are NSString literals. More specifically, they look they are being used as formatting strings for printf style functions.

  3. I believe that they are called ‘format placeholders’, as suggested by this wikipedia article: http://en.wikipedia.org/wiki/Printf_format_string#Format_placeholders
