Question

Here’s how I’m setting it up:

self.df = [[NSDateFormatter alloc] init];
[self.df setFormatterBehavior:NSDateFormatterBehavior10_4];
[self.df setDateFormat:@"posted: MM-dd-YYYY"];

Here is how I am calling it in my trace:

 NSLog(@"%@, %@, %@, %@", df, post.date, [post.date class], [df stringFromDate:post.date]);

Here’s the output:

<NSDateFormatter: 0x8440d60>, 2012-02-09 12:40:38 +0000, __NSDate, 

It’s not null, it’s “”.

The post class with the date property is autogenerated by core data. I can’t see how that makes a difference, but it’s the only thing that seems even slightly unusual.

Answer 1

You cannot use setDateFormat like that.

I tried this code and it worked:

[self.df setDateFormat:@"MM-dd-YYYY"];

Now, you can do:

NSString *myString = [NSString stringWithFormat:@"posted:%@", [df stringFromDate:post.date]];
