iOS Question use timer when my app go to background

cloner7801 · Oct 30, 2016

Hello
I need to use timer when my app go to background in iOS.
Timer is disable when app is background.
I found below link that i can enable timer in background in swift and objective-c.

link : http://stackoverflow.com/questions/...n-lock-on-my-application-with-swift-and-ios-8

Anybody can use it in Inline Objective C code?

Thanks

B4X:

App.IdleTimerDisabled = True

However it has nothing to do with background timers. It prevents the device from sleeping while your app is in the foreground.

You can use background fetch mode if you want to run code in the background.

You cannot run a timer in the background.

Background fetch: Background Fetch (Downloads)
Note that Apple will not approve your app if you are using it to monitor the battery.

Didn't exist way to check battery level in background and play audio?

Technically yes. But Apple will not approve it. You can read more about the background allowed tasks here: https://developer.apple.com/library.../BackgroundExecution/BackgroundExecution.html

You can play in background and count the time... Approved by Apple
