How to format Facebook/Twitter dates (from the JSON feed) in Objective-C

Question

For my iPhone application...

I am looking for a way to format the Facebook created_time JSON property value.

\"created_time\": \"2010-12-0

Answer 1

Just to complicate things a bit, the JSON response of the Twitter Search API currently returns a date format (inherited from Summize) which is something like:

@"Sun, 05 Jun 2011 12:25:47 +0000"

To convert this to NSDate, use:

NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:@"eee, dd MMM yyyy HH:mm:ss ZZZZ"];
NSDate *date = [dateFormatter dateFromString:@"Sun, 05 Jun 2011 12:25:47 +0000"];
