Retrieve multiple objects by their objectId (iOS)

Hello,
I have an array with objectIds, and I want to get the object for each objectId from that array. How should I do this? (optimum)

you can load object for each object id using loop and method findByIdAsync https://backendless.com/documentation/data/ios/data_basic_search.htm or you can use query like this:

objectId in ('B434C5EA-7C9F-3D35-FF95-CB22884B0700', 'object-id-2')

Ok, thank you!
