How to use messageListWithFetchAttributes in MailCore for iOS?

Question

As the title mention,there is no document nor example for this function.Can anyone show me the way how to use it? FYI,I want to get the messages with attributes,something like messages with uid larger than xxxx.Thx for Advanced.

Answer 1

I finally use messageListWithFetchAttributes to get all the messages,then sort the list with uid, then I can get the messages with uid larger than xxxxx.Even it is not an efficient way,but it works.
