ios - MagicalRecord date parsing -

i've got date in following format:

2013-05-04t05:07:09+00:00

i'm using magicalrecord map nsdate automatically. far can see above date format should comply magicalrecord's default date format: yyyy-mm-dd't'hh:mm:ss'z'.

i have tried custom dateformat entry in attribute's user info (see this article):

yyyy-mm-ddthh:mm:ss+z, yyyy-mm-dd t hh:mm:ss z, yyyy-mm-dd't'hh:mm:ss'+'z

but none of them work in order have parse date , returns nil regardless of setting custom dateformat or using magicalrecord's default format.

let's @ string:

2013-05-04t05:07:09+00:00 

this is:

1. four digit year
2. hyphen
3. zero-padded month
4. hyphen
5. zero-padded day of month
6. 't' character
7. zero-padded hour
8. ':' character
9. zero-padded minute
10. ':' character
11. zero-padded second
12. timezone (with direction gmt , separating colon)

thus, according the date format specifiers documentation, pattern you'd want is:

yyyy-mm-dd't'hh:mm:sszzzzz 

also, sure use en_us_posix locale nsdateformatter.
