RestKitObjectMapping 数组关闭空对象
我想在 Capital images 对象属性中映射 CapitalImage 对象。
//------------------------ The mapping I try to
[RKMIMETypeSerialization registerClass:[RKNSJSONSerialization class]
forMIMEType:@"text/html"];
RKObjectMapping *CapitalImageMap = [RKObjectMapping mappingForClass:[CapitalImage class]];
[CapitalImageMap addAttributeMappingsFromDictionary:@{
@"src": @"src"
}];
RKObjectMapping *CapitalMap = [RKObjectMapping mappingForClass:[Capital class]];
[CapitalMap addAttributeMappingsFromDictionary:@{
@"name": @"name",
@"text": @"text"
}];
[CapitalMap addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"images" toKeyPath:@"images" withMapping:CapitalImageMap]];
NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:CapitalMap
method:RKRequestMethodAny
pathPattern:nil
keyPath:nil
statusCodes:statusCodes];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.a10073.de4.dp10.ru/icapitals/capital.php"]];
RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[responseDescriptor]];
[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
Capital *article = [result firstObject];
NSLog(@"Mapped the article: %@ , %@", article.name,article.images.description);
} failure:^(RKObjectRequestOperation *operation, NSError *error) { NSLog(@"Failed with error: %@", [error localizedDescription]); }];
[operation start];
我得到这个结果
