Why does the background service not work on iOS devices? I gave all the necessary permissions and tried every way. flutter_background_service: I'm using ^0.0.1+21 and it says IOS support.
I'm trying to add a pedometer. It works perfectly in the background on Android, but I could not run it on IOS even though I met all the conditions.
When I close the application, it continues to work on android. How can I make this possible on iOS?

Watched this talk about setting up an android thing device. But ios devices don't support Nearby Connections so how are we supposed to setup this for ios?
You can just download the Android Things Setup Utility from the console and still go through the setup, so no need to use an Android Device for that.
This page tells you how to do the setup without a phone.
I'm using MobileFirst Platform 7.1 with Paho MQTT (Internet of Things), I'm trying to implement a Hybrid Application with mqtt for Android and iOS.
I have tested the app in Android and it is working as expected, when it is in the foreground and background,
While in iOS, it does not work as expected. It works correctly in the foreground, but not in the background. I was testing using the iPhone Simulator of XCode and iPhone 6.
I found a project which implemented with MobileFirst and MQTT. from https://developer.ibm.com/mobilefirstplatform/documentation/integration/mq-telemetry-transport/
i am just adding host and port number and adding android,ios environment.but same problem facing android working iOS not.
at this moment what can i do ?
UPDATE:
in iOS, it works correctly foreground.but when i send background the "MQTT client" connection lost form broker.
this method fire :
this.client.onConnectionLost = function() {
alert("Connection lost!");
};
on the other hand , android , windows it work perfectly for foreground and background
For example :
I have a room there have a PIR sensor. it work like publisher . my application user is a subscriber .
when user out the room that that time she open application,subscribe and
send application background.
anytime someone entire the room that time , she will be get a notification.
Details on how to run in the background on iOS can be found here. This link also lists the actions that Apple allows to run in the background, if your app does not meet those criteria then it is likely to get bumped from the app store.
The list also shows which UIBackgroundModes to place in your Info.plist to flag that your app needs background access.
I can not found at least one way to mange it for hybrid application ,tried with several way ,failed and mange it easily for native application MQTT iOS background.

Plan support for new platforms (iOS, Windows Phone)
Add background service support in Android version

I have implemented an app and I need a vibrate function to invoke on a button click in angularjs. It works fine on android, but on iOS it says that navigator is undefined.
I have used the below plugin for the vibrate function
https://github.com/apache/cordova-plugin-vibration
Is there any workaround I need to do get it work on iOS?
Maybe the device is muted? I had this issue where everything was logging correctly but my system volume was off. This post on Android solved it for me. In case your phone has different types of volumes (media, call, etc), un-muting System volume is what solved my trouble.
be sure that the device is un-muted. Many (most) devices will "mute" the vibration as well as the audio.
I'm looking for a solution for the following developing problem:
We are developing an ios (on iPhone, ios 8) application, based on the indoor positioning system, and we have found the IndoorAtlas geomagnetic solution. It is very good, but I don't know, how to solve that keeping running the IndoorAtlas in the background, if the user exit from the app or put the app in the background?
Thanks very much!!
This is not possible in normal application. Only certain type of applications can execute code in background, and even those are only woken up for the related callbacks of the application type.

In your case, the location background mode could work.
I'm making an app for jailbreak that lock the device when the user launch the app. I've tried GSEventLockDevice(); from GraphicsServices.framework but this does not work properly because it locks the screen but does not power off the screen. Is there another way to lock the screen without MobileSubstrate?
Just as another alternative, check out this answer, which uses SBDimScreen(). You could use that in conjunction with GSEventLockDevice().
It appears that you may now (iOS 5+) need to add an entitlement to your app to use this call successfully. If you haven't done that before, here is an example of how to do so. Obviously, in this case, the entitlement in question must be changed to com.apple.backboard.client.
You also might see if #VictorRonin has experimented with this, as he commented on the question I linked to. I tested SBDimScreen() on a jailbroken iOS 4.2.1 device, but my newer devices are currently unavailable to run this test. I'll try it later on iOS 5.x and post an update.
Note: the answer I linked to from Elias has a different call altogether for iOS 6.
Look at these several questions:
Simulating System Wide Touch Events on iOS
Simulating System Wide Touch Events in iOS without jailbreaking the device
How to send a touch event to iPhone OS?
The idea is that you can simulate system wide events. One of events is power down event. If you simulate it, it will turn off device and will lock it.
BTW. You may be interested to google more on GSEvent which is the key for even simulation.
Here are couple of useful links:

Also, this approach isn't limited to jailbroken phones. It works on jailed phone too (however, you won't be able to post it to AppStore).
