RKValueTransformers «не удалось преобразовать значение в NSDate»
Я использую RestKit, и тяну в RSS-канал.
Я получаю этоошибка для каждой даты, связанной сRKValueTransformers говоря (например):
"Failed transformation of value 'September 04, 2014 09:58:01 PDT' to NSDate: none of the 10 value transformers consulted were successful."
Это говорит мне:
Failed transformation of value at keyPath 'pubDate.text' to representation of type 'NSDate'
а также:
{NSLocalizedDescription=Input value is not a valid ISO 8601 string: 'September 01, 2014 14:53:30 PDT'}
Я верю, что я правильно вытягиваю текст, но не могу понять, является ли это чем-то или есть что-то еще, что является причиной того, чтодата из XML не превращается в строку Я могу использовать.
Есть идеи? Спасибо!
ОБНОВИТЬ:@property (nonatomic, strong) NSDate *pubDate;
BFar: Это то, что я пробовал:
RKObjectMapping *rssFeedObjectMapping = [RKObjectMapping mappingForClass:[FeedRSS class]];
[rssFeedObjectMapping addAttributeMappingsFromDictionary:@{
@"title.text" : @"title",
@"link.text" : @"link",
@"description.text" : @"description",
@"pubDate.text" : @"pubDate"
}];
с вашей помощью:
// My Date String from XML
NSString *dateString = [NSString stringWithFormat:@"%@", feedDan.pubDate];
// String in XML Feed has format of: "September 04, 2014 09:58:01 PDT"
// New
NSDateFormatter *dateFormatter = [NSDateFormatter new];
[dateFormatter setDateFormat:@"MMMM dd, yyyy HH:mm:ss z"];
//[RKObjectMapping addDefaultDateFormatter:dateFormatter];
// Above line is deprecated: "Configure [RKValueTransformer defaultValueTransformer] instead"
// Not sure if below is correct
[[RKValueTransformer defaultValueTransformer] addValueTransformer:dateFormatter];
NSDate *date = [dateFormatter dateFromString:dateString];
NSDateFormatter *otherFormatter = [NSDateFormatter new];
// API shows "2014-09-04T20:22:05Z", but prints in label as 2014-08-27 16:14:04 +0000
[otherFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss'Z'"]; // "2014-09-04T20:22:05Z" to 2014-08-27 16:14:04 +0000
NSLog(@"Stack: %@",[otherFormatter stringFromDate:date]);
