Converting an ISO 8601 timestamp into an NSDate: How does one deal with the UTC time offset?

by

No need to remove the :’s. To handle the “00:00” style timezone, you just need “ZZZZ”:

Swift

let dateString = "2014-07-06T07:59:00Z"

let dateFormatter = NSDateFormatter()
dateFormatter.locale = NSLocale(localeIdentifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZZZZ"
dateFormatter.dateFromString(dateString)

Objective-C

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
dateFormat.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"];
NSString *input = @"2013-05-08T19:03:53+00:00";
[dateFormat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZZ"]; //iso 8601 format
NSDate *output = [dateFormat dateFromString:input];
NSLog(@"Date output: %@", output);
