NSString datetime to NSDate

Question

I'm having a hard time trying to convert a NSString to NSDate. I try lots of date format convinations, but no worked.

My string is: 5/17/2013 12:00:00 AM

And I'm using:

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"M/d/y hh:mm:ss a"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
NSDate *cI = [dateFormat dateFromString:@"5/17/2013 2:00:00 AM"];
[dateFormat release];

I also try with:

M/d/y h:mm:ss a
M/d/y hh:mm:ss
M/d/y h:mm:ss

But always cI is a nil.

When/where do you log "cI". Are you NSLogging it immediately after the dateFromString, or somewhere else? — Hot Licks, May 29 '13 at 18:51
Once again, where are you logging "cl"??? How do you know it's nil right after the dateFromString operation?? — Hot Licks, May 30 '13 at 00:27

Use:

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"MM/dd/yyyy hh:mm:ss a"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
NSDate *cI = [dateFormat dateFromString:@"5/17/2013 2:00:00 AM"];
[dateFormat release];

Output: 2013-05-17 02:00:00 +0000

@Tony: as you can see in screen shot, its working!!! – Anoop Vaidya May 29 '13 at 16:43
setDateFormat is different in the message and in the screen. Any way I try both but no works. May be is something different in my enviroment. – Tony May 29 '13 at 16:55
yes just for showing you, even that works.... even your code is good. try clean and build again. – Anoop Vaidya May 29 '13 at 16:57
I create a new project copy&paste the code and I also get nil :S – Tony May 29 '13 at 17:04

*cough* don't forget to set the en_US_POSIX locale (see http://developer.apple.com/library/ios/#qa/qa1480/_index.html ) – Tommy May 29 '13 at 19:43
Thank you very much Anoop, this solve my problem: [dateFormat setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"]]; – Tony May 30 '13 at 18:39
