I need to display hours and minutes only. I could just force the
user to my chosen format, but I'd rather they have their own choice
of 12/24 hour clock etc.
I figured that the NSDateFormatterShortStyle constant would pull
what I needed, but the docs say:
"The format for these date and time styles is not exact because
they depend on the locale, user preference settings, and the
operating system version. Do not use these constants if you want an
exact format."
So, if I want to set a date formatter up to display hours and
minutes only, where can I reliably pull this information from?
Will I have to take the user's preference from NSUserDefaults and
manually parse it? NSDatePicker seems to manage things properly by
itself!
I understand it like this:
1. If you want the user format, use style. If you use "short" time
style, most users will get the default short time format, because
most users do not change preferences. there is statistics about 90%
of users never changing defaults, but I don't know it it is correct
for mac users (probably not). Users that have changed the short style
(see System Preferences > International > Format > Customize) will
get exactly what they see as correct short style, which can be anything.
2. If you want specific format, use the ICU library format string.
The user will get exactly what you define.
See http://icu.sourceforge.net/userguide/formatDateTime.html
