I’m working on a project that interfaces with Google Data APIs. I have several independent classes for HTTP GET and HTTP POST for interacting with Google, and they are all asynchronous. I’m concerned that a user might touch the home button before operations are finished, thus causing rifts in server/client sync parity. I don’t understand the background task API, as it seems that I have to encapsulate every single GET or POST request in a background block, and each block has to be called from my Application Delegate. Is this true? If so, it would cause a major headache to try to rewrite a lot of my existing upload and download logic.

Thanks for your input! =)

    I recommend to queue all the HTTP Requests using a NSOperationQueue and then only use one background task. You can specify how many operations are allowed to run in parallel with setMaxConcurrentOperationCount.

    When you use ASIHTTPRequest framework, this is very easy with ASINetworkQueue, a subclass of NSOperationQueue.
    Continuing downloads in the background is easy too: http://allseeing-i.com/ASIHTTPRequest/How-to-use#background_downloads_ios.
