I'm trying to do multiple request in background to download many jsons and check data from them but I don't know how to use AFNetworking in that case.
I tried to do like Wiki explaings but when it's going to download the second file then the app breaks. I want to do all the process in background.
Thanks
AFNetworking will definitely handle this. We use it for exchanging data with a RESTful set of services. The things to keep in mind:
Hope this helps to point you towards a solution to your problem. Without more detail in your question, it's difficult to give you a specific answer.
Check out AFHTTPClient
's
enqueueBatchOfHTTPRequestOperations:progressBlock:completionBlock:
, which lets you enqueue multiple requests operations at once with the added bonus of having a completion handler that is called when all of those requests have finished, as well as a block for tracking the progress. Also note, that every single operation can still have its own completion handler (useful if you have to process the results of a request, for example).
If you don't need to customize the request operation (and don't need individual completion blocks), you can also use enqueueBatchOfHTTPRequestOperationsWithRequests:progressBlock:completionBlock:
, which allows you to pass an array of NSURLRequest
directly without having to build the operations yourself.
