I recently used RestKit to handle my net request affairs. There is a solution for the sort with the sort descriptor. But there is no sort key for the data sent by the server.
How can I keep the data in the same sequence as the server.
There is a solution that I can add a sortID in the object, but this is not very elegant. I want to know if there is any api in RestKit for this problem?
You should add sortID to the object - this is the appropriate solution. To populate it with a value you need to use the @metadata made available to your mappings:
@"@metadata.mapping.collectionIndex" : @"sortID"
This code assumes that you are specifying your mapping with a dictionary (addAttributeMappingsFromDictionary:).
Documented here, the collectionIndex provides you with an NSNumber representing the order of the item in the response data.
