ios - Specify the time offset with an NSDateFormatter (-0500) -

i have date strings similar these:

2013-01-25 00:00:00 -0500 2013-01-22 00:00:00 -0700 2013-01-26 00:00:00 -0200 

i want use nsdateformatter create nsdate using these kinds of strings. know how use formatter first part of date (2013-01-25 00:00:00), don't know how specify offset part (-0500, -0200, etc). here's code start of date string:

nsdateformatter *dateformatter = [[nsdateformatter alloc] init]; [dateformatter setdateformat:@"yyyy'-'mm'-'dd hh':'mm':'ss"]; nsstring *datestring = @"2013-01-25 00:00:00"; // <-------- truncated ---- nsdate *date = [dateformatter datefromstring:datestring]; nslog(@"date: %@", date); 

how can working -0500 part? tried sssz, didn't work (gave null date).

try this:

nsdateformatter *dateformatter = [[nsdateformatter alloc] init]; [dateformatter setdateformat:@"yyyy'-'mm'-'dd hh':'mm':'ss zzz"]; nsstring *datestring = @"2013-01-25 00:00:00 -0500"; nsdate *date = [dateformatter datefromstring:datestring]; nslog(@"date: %@", date); 

i get:

date: 2013-01-25 05:00:00 +0000
