ISO8601DateFormatterValueTransformer
A small Objective-C library that integrates Peter Hosey's ISO8601DateFormatter with RKValueTransformers.
The implementation is done by adding RKValueTransforming conformance to the ISO8601DateFormatter via a category.
Examples
Usage
Basic usage is identical to all other RKValueTransforming classes.
#import "ISO8601DateValueTransformer.h"
RKISO8601DateFormatter *dateFormatter = [RKISO8601DateFormatter defaultISO8601DateFormatter];
// Transforming NSDate -> String
NSString *dateString = nil;
NSError *error = nil;
BOOL success = [dateFormatter transformValue:[NSDate date] toValue:&dateString ofClass:[NSDate class] error:&error];
// Transforming NSString -> NSDate
NSDate *date = nil;
success = [dateFormatter transformValue:@"2013-09-12T07:24:56-04:00" toValue:&dateString ofClass:[NSDate class] error:&error];Configuration as Default Date Transformer
Adding the date formatter to the default value transformer at position 0 ensures that it is used ahead of all other NSString <-> NSDate value transformers.
#import "ISO8601DateValueTransformer.h"
RKISO8601DateFormatter *dateFormatter = [RKISO8601DateFormatter defaultISO8601DateFormatter];
[[RKValueTransformer defaultValueTransformer] insertValueTransformer:dateFormatter atIndex:0];Credits
