Hello!
I have several http requests. Each request returns json stucture and then I have to parse json and add information to my core data model. But I can't add some information to core data, because this information refers to the data returned from another request. How can I better organize to some requests were made only after the others are already returned data? What is the best way in this case?
Best regards,
Aleksey.
I do this by putting each request in a separate NSOperation and then using NSOperation dependencies to ensure an appropriate ordering. For a high-level discussion of this technique, see WWDC 2015 Session 226 Advanced NSOperations.
You should also read this thread, where I posted my latest spin on this technique.
