Does -dateWithString: really not support the "international [standard!] string representation" of ISO 8601?? What's the right way to convert such an xsd:dateTime to an NSDate?
+[NSDate dateWithString:] is, I think, configured to recognize one particular date format, which depends on your system locale. It's not very useful. What you want to do is customize an NSDateFormatter object to recognize your format, and then parse using it.
Here's some code I wrote recently. This sets up the date formatter, which only needs to be done once:
static NSDateFormatter *sISO8601 = [[NSDateFormatter alloc] init];
...
sISO8601.timeStyle = NSDateFormatterFullStyle;
sISO8601.dateFormat = @"yyyy-MM-dd'T'HH:mm:ss.SSSZZZ";
Then you parse a date from a string like:
NSDate *date = [sISO8601 dateFromString: str];
Actually, looking at my code, there's a gotcha where the
NSDateFormatter doesn't seem to understand the "Z" suffix. The best
workaround I could find was this kludge:
// Formatters don't undnerstand "Z" timezone, so replace it with "GMT":
if( [str hasSuffix: @"Z"] )
str = [[str substringToIndex: str.length-1]
stringByAppendingString: @"GMT"];
Do that just before the -dateFromString call. —Jens
