Is there a simple way of converting an ISO8601 timestamp to a formatted NSDate?

Solution 1:

I have a similiar but slightly more complex problem, and I've found a very simple solution!

The problem: My incoming ISO8601 dates look like this: 2006-06-14T11:06:00+02:00 They have a timezone offset at the end.

The solution: Use Peter Hosey's ISO8601DateFormatter which you can download from here.

ISO8601DateFormatter *formatter = [[ISO8601DateFormatter alloc] init];
NSDate *theDate = [formatter dateFromString:dateString];
[formatter release], formatter = nil;

and

ISO8601DateFormatter *formatter = [[ISO8601DateFormatter alloc] init];
NSString *dateString = [formatter stringFromDate:[twitch dateTwitched]];
[formatter release], formatter = nil;

Solution 2:

You need another formatter to handle the output. Put this after your code:

NSDateFormatter *anotherDateFormatter = [[NSDateFormatter alloc] init];   
[anotherDateFormatter setDateStyle:NSDateFormatterLongStyle];
[anotherDateFormatter setTimeStyle:NSDateFormatterShortStyle];
NSLog(@"%@", [anotherDateFormatter stringFromDate:myDate]);

Solution 3:

Here is sample code from apple

    NSDateFormatter * formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss'Z'"];
    NSDate *date = [formatter dateFromString:dateString];
