Hello,
I have a date event returned as a date time string from a feed in the
following format,
"Tue 01 Jul 2008 15:00:00 +0100"
I'm assuming this is GMT plus one hour, I'd like to convert this
string to
the to a more user friendly date time string such as,
"Today at 9:00am" or "Tue Jul 01, 2008 9:00am"
that would take into account the current Time Zone setting of the Mac
displaying the date event. I've looked at the NSDateFormatter and
NSCalendarDate, but didn't see anything that takes into account the
Time
Zone setting on the current Mac. Does anyone know of where I might
find or
have a sample of a code snippet that does something similar to this?
So there are two parts to your problem. First you need to take the
original string and create an NSDate object from it. To do this,
create an NSDateFormatter and set up its -dateFormat property to match
the "Tue 01 Jul 2008 15:00:00 +0100" format. This link may be handy
for formatting info:
file:///Developer/Documentation/DocSets/com.apple.ADC_Reference_Library.CoreReference.docset/Contents/Resources/Documents/documentation/Cocoa/Conceptual/DataFormatting/Articles/dfDateFormatting10_4.html
#//apple_ref/doc/uid/TP40002369-DontLinkElementID_13
Now that you have a NSDate object, you'll want a second
NSDateFormatter that converts the date into the desired string format.
For the most part, you can achieve the "Tue Jul 01, 2008 9:00am" style
dates with -setDateStyle: and -setTimeStyle: I would STRONGLY
recommend you use this rather than try to specify your own date format
string as it means dates will match the user's preferences.
You can then subclass NSDateFormatter to supplement the behaviour to
generate "Today" etc. when appropriate. For all I know, there may
exist a 3rd party NSDateFormatter subclass to do this already.
