iOS NSDateFormatter Issues

[nomar383]

Okay, I'm sick of playing with this. Break it to me, what's up? This compiles fine, but I can't seem to get the date formatter to work. That NSLog displays nothing.

//create formatter and format
	NSDateFormatter *dtsFormatter = [[[NSDateFormatter alloc] init]  autorelease];
	[dtsFormatter setDateFormat:@"%j"];
	
	//run the string through the formatter
	NSDate *testDate = [NSDate date];
	NSString *formattedDate = [dtsFormatter stringFromDate:testDate];
	NSLog(formattedDate);

Here's your problem:

[dtsFormatter setDateFormat:@"%j"];

What is %j? That's not a valid date format in your case.

Well, what is the proper formatter to get the day of the year in a 001-366 format? I've used the "%j" convention with other objective c classes and it has worked... 🙁

Beautiful, I got it working 🙂

Just needed to replace the %j with D, thanks!

Actually, if you want 001-366, you'll want @"DDD".

Really? It seems to be working with one D...

By the way, when you get the day of the week using the same method, it returns 1-7 rather than 0-6 as was the case with the formatter I used in previous versions of my app. Interesting

EDIT: DDD also works, so what is the difference?

Leading zeros.

Leading zeros.

Thanks for the clarification, and your time on this one
