如何使用NSDateFormatter解析ISO 8601 / RFC 3339时区？

Question

我有一个这样的日期字符串（ISO 8601 combined date and time representation或RFC 3339）：

  

2010-09-04T19：13：00Z

但是如何配置NSDateFormatter以接受此时区格式？

Answer 1

[NSDateFormatter setDefaultFormatterBehavior:NSDateFormatterBehavior10_4];
NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
[formatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZ"];
NSDate *date = [formatter dateFromString:'2010-09-04T19:13:00Z'];

Answer 2

了解Apple推荐的内容here：

// Convert the RFC 3339 date time string to an NSDate.

NSDateFormatter *rfc3339DateFormatter = [[[NSDateFormatter alloc] init] autorelease];

NSLocale *enUSPOSIXLocale = [NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"];

[rfc3339DateFormatter setLocale:enUSPOSIXLocale];
[rfc3339DateFormatter setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss'Z'"];
[rfc3339DateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];

NSDate *date = [rfc3339DateFormatter dateFromString:rfc3339DateTimeString];
