I configured my app for receiving location update in the background, and everything works fine except one thing - location not update during phone call (when used only 3G, WI-FI is off).
Can someone explain me why this happens?
Whenever you make a call and access data at the same time then you may see this type of problem, it totally depends upon on the mobile phone that you are using. To access data during calls, your phone should support dual band technology. When making a call you are already using some bandwidth. This same bandwidth is used for accessing internet by your phone if it does not support dual band channels then you will face this type of problems. Also, sometimes the network providers themselves do not allow you to make a call and access internet at the same time. Try with other mobile network or other mobile phone. For confirming whether you are getting data during the call or not, try to open some other apps like "youtube" during the call and check whether you are able to view the app. If you are able to view the app then you are doing something wrong with your location based services code. Ask another question by posting your code for fetching the location, so that We can help you.
you'll go to setting -- privacy -- location on -- your app -- set always or while using app

What I am trying to accomplish is to make ios app that listens to signal (not yet defined in which form) and then call the number specified in received message. I've found that is impossible when app is in background due to Apple privacy policy, but I want it to be possible only when in foreground.
I am wondering if it is possible to develop similar mechanism like when you connect iPhone to MAC so you can call using your MAC. But I want to use this funcionality from Windows too.
For example. Lets say that I have Windows app written in Java that stores contacts. I click call and the number is send to iPhone (like I said using not specified yet method) and then iPhone calls that number.
Is there any possibility to accomplish this. If yes, what the best way to send and receive message with number (for example bluetooth ).
I was trying to get a specific info before a IOS App development task which I searched but couldn't find anything relevant.
Wanted to know whether this requirement restricts (non compliance issue as per publish guidelines) the app to be published in App Store with features as below
User scans and lists all available wifi connections in a tableview
Selects one of the Wifi connection and connects on button click
Stores the password and SSID for future connections.
Would there be any compliance issue related to the same functionalities when submitting to IOS app store. One of my colleague have advised me about the same but not able to explain why? Which I tried to find out searching the internet, but too specific to find anything relevant. Deeply appreciate an Expert advise on this.
Thanks in advance.
I can't find anything in the Review Guidelines that would object your app idea: https://developer.apple.com/app-store/review/guidelines
A couple of areas where you should have a more detailed look:
2.5.1 Apps may only use public APIs.
2.5.9 Apps that alter the functions of standard switches, such as the Volume Up/Down and Ring/Silent switches, or other native user
interface elements or behaviors will be rejected.
5.1 Privacy
Technically, I'm not sure if it's even possible to change the WIFI not via the settings app, so I'd have a look their first. (https://apple.stackexchange.com/questions/1592/is-there-an-ipod-app-to-easily-switch-wifi-on-and-off)
I don't believe I've ever seen an app or a way to change SSID outside the Settings app. I explored a way to detect network changes, connects, disconnects, which work fine while the app is running. I was never able to influence how the user connected, just that a change happened. It also falls apart pretty quickly when the user backgrounds the app. Trying to keep a background task open long enough to poll the current connection fails pretty fast.
I wish Apple would provide some system level notification of Wifi connect events. This could be very useful to developers that want a little more control than Background App Refresh events.
I'm making a framework for iOS that collect data from the phone (GPS, WiFi, etc) and sends to a server and notifies the user on events.
My problem is that if two or more apps use the framework on the same device it will consume the battery and I only need to send the data from one app because the collection continues in the background.
Is there any way to know if these multiple apps are running and notify the app that other app is collection and sending the data?
No. The apps are sandboxed and cannot interact.
The framework will have no way of communicating with the other apps unless it sets-up some sort of networking on the client (not advised).
I wouldn't worry about it.
I'll probably look the problem inside out. When I start receiving info on the server from same ip/mac combination simultaneously I'll return a flag to all but one client on that particular device. When my framework receive that kind of flag, it will stop sending data, because someone else is already doing the same.
PS Your framework sounds like creepy spy thing though :)
My goal is to listen only and not modify the outgoing call event and send GPS coordinates to server from background. I'm not even interested in phone number being dialed, what I only need to know is whether the current call is Emergency call.
I've accomplished this easily in android, by following this tutorial.
However some googling showed that, this is a big pain in the ios world.
The only solution I think is to write dialer app from scratch and manage all the events by myself (if that's even possible), but I think it's too overcomplicated
I'm completely new to ios and please let me know, how would you solve this problem guys?
There is no way this will be possible on iOS unless you were planning to release and app for jailbroken phones (and even then I'm not sure it is). The Core Telphony framework has the methods you can use: https://developer.apple.com/library/ios/documentation/NetworkingInternet/Reference/CoreTelephonyFrameworkReference/index.html
In advance I am sorry for my English.
The task consists in defining, whether there is a person in a certain place (at certain office, for example), and to activate depending on it certain possibilities of the appendix.
At first I thought of definition of information on WiFi (or check of the same SSID, or automatic connection to the hidden network with set in the SSID appendix and the password), but, seemingly, not to make it without jailbreak (if somebody knows how - please, answer).
I think, GPS - not the best exit as it is possible to be out of the room, using it.
By the way, I already saw apps determining by WiFi of a point of access so it can be made somehow. I guess.
Actually, question. How it is better to define in the application, whether there is a device within, for example, premises of office?
Basically, if you know location coordinates you can safely use CoreLocation framework. Whether your target device supports region monitoring it will be perfect. It uses not only GPS, but WiFi and GSM as well
Look here: https://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CLLocationManager_Class/CLLocationManager/CLLocationManager.html
If you really need to get network name you can play with CNCopyCurrentNetworkInfo function of CaptiveNetwork framework.
