Objective C - NSDateFormatter returns nil ??

Question

NSDateFormatter* dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss.sss"];
self.date = [dateFormatter dateFromString:dateString];

the code works fine with this string

• "2007-06-10 06:31:54.935"

but doesn't work with this one (it returns nil if the time is set to 0):

• "2007-06-10 00:00:00.000"

Answer 1

Try using @"yyyy-MM-dd HH:mm:ss.SSS" (uppercase S for the fractional seconds).
See Date Format Patterns guide.
