"count_total":164,
"pages":164,
"posts":[{"id":2966,
"type":"post",
"title":"title here",
"content":"here content",
"date":"",
"attachments [
"comment_count":0,
"thumbnail":""]
}]
}
one class Attachments and one class articles

}

@property (strong, nonatomic) NSMutableArray *post;
@end
in viewcontroller.m
RKObjectMapping* attachmentsMapping = [RKObjectMapping mappingForClass:[Attachments class]];
[attachmentsMapping mapKeyPathsToAttributes:@"thumbnail", @"thumbnail", nil];
RKObjectMapping *postMapping = [RKObjectMapping mappingForClass:[articles class]];
[postMapping mapKeyPathsToAttributes:@"title",@"title",@"date",@"date",nil];
[postMapping mapKeyPath:@"attachments" toRelationship:@"attachments" withMapping:attachmentsMapping];
[objectManager.mappingProvider setMapping:postMapping forKeyPath:@"posts"];
[self searchRequest];
- (void)objectLoader:(RKObjectLoader *)objectLoader didLoadObjects:(NSArray *)objects {
NSLog(@"objects[%d]", [objects count]);
[posts removeAllObjects];
for (articles *t in objects) {
[posts addObject:t];
}
[self.tableView reloadData];
}
i get this error
[RKObjectMappingOperation transformValue:atKeyPath:toType:] Failed transformation of value at keyPath 'attachments'. No strategy for transforming from '__NSArrayM' to 'Attachments'
What's wrong?
Thanks
