iOS app rejected for VoIP background mode

由 霸气de小男生 提交于 2021-02-08 04:43:45
问题 I have developed an application that uses Linphone VoIP API to receive incoming calls, but I don't want the user to make outgoing calls (because that's not what my app is supposed to do). I have enabled VoIP background mode in my .plist but the app got rejected because "it would be appropriate to add a calling-out feature or remove the VoIP background mode". Now I don't want to add call-out features but I totally need VoIP background mode. How am I supposed to make my app run in background

How to keep GCKCastSession alive when app goes to background

由 霸气de小男生 提交于 2020-01-10 20:14:43
问题 I'm using latest Google Cast SDK for iOS (version 3.1.1.10003) and our app is remote controlling Google Cast devices, e.g. it changes their volume. It needs to do so also when our app goes to background. However, GCKSessionManager invokes suspendSessionWithReason: when the app goes to background. This said, the session will be suspended and thus our app can't control it any longer. How can I make GCKSessionManager not suspend sessions when apps go to background? Edit : I'm providing a

Is using Core Location for performing functionality in the background appropriate?

由 拈花ヽ惹草 提交于 2019-12-29 09:25:10
问题 Lately, I've notice that there are a few applications request to access the user's location for performing some functionalities in the background. For example : Application for scanning and uploading the user's photos for backup purposes, so when entering the background state, it keeps scanning and uploading. What am I asking: If there are Background Execution mechanisms for executing Background Tasks (Select Target -> Capabilities -> Background Modes), so why using the Core Location for

Just how persistent are Firebase database observers?

由 僤鯓⒐⒋嵵緔 提交于 2019-12-23 05:31:05
问题 I decided to run a test on the XCode iOS simulator to see if an observer to a location in the Firebase database would continue to fire even when the app is in the background. Turns out it does, but I am wondering if this is indefinite until the app terminates or if it will actually stop after some time. It's been a very long time and the observers still fires whenever I manually update the value in the database that the observer is looking at. Also note that I don't have any background modes

由 ぐ巨炮叔叔 提交于 2019-12-10 13:22:57
问题 Requirement - I am building a hyperlocal app which will provide offers to user based on his location.
