Question

I thought I had the “hard” part done but that doesn’t seem to be the case. I retrieve a date from an RSS feed that I would like to convert to a NSDate and then change it to the simple format (MM/DD/YYYY). The date comes in this format on the RSS feed:

Thu, 1 Nov 2012 17:41:56 CST

I have converted it to an NSDate successfully.

NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"E, d MMM yyyy HH:mm:ss zzz"];
NSDate *date = [[NSDate alloc] init];
//[df setDateStyle:NSDateFormatterMediumStyle]; Using these seems to change what it expects from the string I guess?
//[df setTimeStyle:NSDateFormatterMediumStyle];
date = [df dateFromString:string];
[self.tempItem setPubDate:[df dateFromString:string]];
NSLog(@"%@", [df dateFromString:string]);

So I get my date just fine, but like I said before I want to just convert it to a simple date.
When I use setDateStyle I end up with null values. When I don’t use it, I get correct dates, just not in the format I want it to end up being.

Answer 1

just not in the format I want it to end up being.

Because NSLog() doesn’t know about the format – how would it? NSDate doesn’t have any built-in “format”. You have to obtain a string from the date object by using NSDateFormatter once again. Basically the workflow you’ll have to use is roughly:

• retrieve an NSString from the RSS feed
• Create a date formatter
• Set its format according to the format of the string
• Get an NSDate object from the date formatter
• Re-set the format of the NSDateFormatter to the format you desire
• Obtain a properly formatted NSString using the date and the date formatter objects.
