Q: Why iOS is not multitasking the conventional way?

I'm trying to upload a large video (gb) to my iPad using files pro

I use safari on my Mac for that

Inserting the ip to the address bar and...

When the files app is closed, I mean when I switch to another app, the upload stops!!

I think the current multitasking is not convenient for me.

Why doesn't it multitask the true way?

A:

Because it is a mobile device with limited resources, so certain sacrifices have had to be made to make sure battery life and device performance is maintained.

    That was right for a mobile phone,

    But I need more from a tablet

    I searched more and found that one of the cases that a service stays live in the background is task completion, but here the task is not completed yet and it remains half done.

    My android fan colleague says your iPad's like a Ferrari in gear 1!

    Background tasks need to have completed within 10 minutes.

     

    If you have such large files to transfer that take more than 10 minutes, why don't you use the iTunes File Sharing feature over USB? That's what it is there for.

     

    I really don't care what your android fan colleague say's. How's the 2 hour battery life on his tablet?

    Honestly, that was a challenge, Android fans are hard believers and they look at the problem, their own way, both of us are gadget geeks and he's trying to convince me that Android powered tools are better fit our (geeks) needs and iOS is for the ordinary users those can't manage the resources themselves.

    At least it has to be enabled somewhere with a warning about the battery

    It sounds like the developer of the app you are using did not write it so that it could continue its file transfers while it is not in the foreground.  That can be done easily while still fitting in the iOS multitasking model.

    Dear Julian,

    Could you please give me a reference on Apple documentation for this your statement:

    "Background tasks need to have completed within 10 minutes."

     

    We are devoloping now application which downloads files from our server inside and in principal 10 minutes is enough for task completion. I just need clear defined rule for this to be sure the application will not be refused.

    Thank you in advance!

    I don't have access to all the latest Developer documentation, but the limit is mentioned under Multitasking in the iOS 4 SDK Release Notes here:

     

    http://developer.apple.com/library/ios/#releasenotes/General/RN-iPhoneSDK-4_0/_i ndex.html

     

    It may have changed again since then though...

    It won't be refused - simply your downloads will be stopped. (Make sure you use a protocol with resume support and you do make use of it - as does many (but not all!), for example, video downloader!)

    That's, more or less, true. Androids are for tech geeks, iOS devices are for the opposite (albeit a lot of geeks also purchase iOS devices because of their technical (hardware) superiority - show me a, most importantly, screen resolution- & quality-wise, better spec'ed Android tablet than the iPad 3!). There was an excellent article on exactly this: http://www.imore.com/2012/06/29/ios/
