Question

Hello guys i saw google plus iphone app uploading my images without the app being active or in background it is closed completely! how i can run a process like this in my app

Answer 1

You are mistaken. This doesn’t happen. The app uploads your photos when you tap it and continues in the background for 10 minutes once the app has been exited using the home button using

- (UIBackgroundTaskIdentifier)beginBackgroundTaskWithExpirationHandler:(void (^)(void))handler

Google even say this is what happens in their instant upload FAQ:

Note: Photos and videos will upload while the Google+ application is
open and for a brief period of time afterwards.

What you want, the ability to run code

“without the app being active or in background it is closed
completely!”

is not possible on iOS
