I wanna build an ios application which must be network specific.i wanna put IP mapping in my app.
it should work in a particular network or simply it should not work in other network except one network which i specify. i have googled but didn't get clear answer.
please let me know any solution for this.
From Apple review guidlines:
2.22 Apps that arbitrarily restrict which users may use the App, such as by location or carrier, may be rejected
It is risky to limit your app to one specific network and it will probably get rejected. All apps should provide minimum functionality to all users that download it. Also there is no ability to limit availability in the App Store to a specific network, you can only limit availability by country.
You can parse the external ip with an external service like this (make a NSURLConnection and parse the result) and provide extra functionality to users from a specific network.

I have written an Android application which, even after termination, still runs a service that listens for phone state transitions. This way, the application was able to detect new phone calls and trigger a certain event, for example the dialog partner's number was stored in a database.
Now I am eager to implement this application on iOS as well, but I cannot figure out if it is even possible to listen for phone calls in a similar way. For all I know so far about iOS, whenever my application is terminated by either the user or the OS, it is not possible anymore to detect new phone calls.
Is there any way I can achieve this, or have I already reached a dead end?
EDIT: As it was said to be too broad:
I want to detect both incoming and outgoing calls at any time. It there a way to do this on iOS 10? I do not want code, I just want to know if it is possible.
Please investigate further App Sandbox principe that Apple is using.
In short:
App Sandbox is Based on a Few Straightforward Principles By limiting
access to sensitive resources on a per-app basis, App Sandbox provides
a last line of defense against the theft, corruption, or deletion of
user data, or the hijacking of system hardware, if an attacker
successfully exploits security holes in your app. For example, a
sandboxed app must explicitly state its intent to use any of the
following resources using entitlements:
Hardware (Camera, Microphone, USB, Printer) Network Connections
(Inbound or Outbound) App Data (Calendar, Location, Contacts) User
Files (Downloads, Pictures, Music, Movies, User Selected Files) Access
to any resource not explicitly requested in the project definition is
rejected by the system at run time. If you are writing a sketch app,
for example, and you know your app will never need access to the
microphone, you simply don’t ask for access, and the system knows to
reject any attempt your (perhaps compromised) app makes to use it.
On the other hand, a sandboxed app has access to the specific
resources you request, allows users to expand the sandbox by
performing typical actions in the usual way (such as drag and drop),
and can automatically perform many additional actions deemed safe,
including:
Invoking Services from the Services menu Reading most world readable
system files Opening files chosen by the user The elements of App
Sandbox are entitlements, container directories, user-determined
permissions, privilege separation, and kernel enforcement. Working
together, these prevent an app from accessing more of the system than
is necessary to get its job done.
My work wants to test their new modems using an iPhone app. We can use a current app or build a brand new one. Third party apps are OK but want to avoid jailbreaking if possible.
We want an app which connects to the network and monitors certain parameters for a set amount of time. We will log attributes from the network and modem. We already know it's possible to test speed, disconnections, reconnection time etc. Some of the parameters we need to track might be more secure or outside Apple's regulations.
These are the responses we are looking for:
Frequency (ie. 2462MHz)
Channel Bandwidth (ie. 20MHz, 40MHz)
Radio Type (ie. 802.11a,b,g,n,ac)
802.11 Deauth Reason code
802.11 Association Status code
How can we track the above attributes using an iOS app?
Are there any apps out there that can track this information? Does iOS have anything for tracking these parameters?
Thanks so much!!
I recently have been very interested in developing iOS apps (for iPhone specifically) that can "communicate" with nearby (geographically) apps.
My networking skills/resources are limited, so I was really hoping to make it a peer to peer app, avoiding the need to host my own server.
It seems like I have a few options, including the newish Multi-peer Connectivity framework, and Location services.
I was hoping someone who has experience writing peer to peer apps could direct me to what they think the most logical approach would be.
Additonal info:
*I am only looking to send text/small pictures (speed is not a priority)
*Detecting nearby (within a mile or so) geographically is the main goal
*Possibly communicate with Android devices (I know multi-peer connectivity lacks this)
Peer-to-peer communication is limited to a range of about 50 meters. To extend the range you can create a mesh using intermediate peers to relay messages. That is how the Firechat app works.
If you want to communicate over greater distances without a mesh I believe you will need to go via the cloud
In terms of communicating with Android, the people who made FireChat are coming out with their SDK. Not sure how/what pricing will be but I assume they will offer this cross platform function. There are of course other ways but I am not that advanced in app development to know them yet.
For a simple chat app there are many free online tutorials that help you create iphone to iphone chat app that can also send images. Range will be limited however to whatever is max for WiFi. Like Keith said, mesh is another option but I believe everyone in the network has to have the app for the data to bounce.
I'm looking for a way to develop an iOS in which I can access all network traffic, (I mean System-Wide) and route it through my app. Something like a proxy server but notice that I want to force the route and access all the traffic not only web requests (Something like what VPN Connections do).
I think that may go a bit beyond Apple limitations regarding App Store Guidelines. Any VPN API accessible for doing that ? Any practical suggestion or description on undocumented and private APIs is really appreciated.
P.S: This article may help understanding what I'm looking for;
To be able to do VPN functionalities you have to create a vpnplugin, the problem is that it's a pseudo-Private API, I'm saying "pseudo" because there are companies that had access to the documentation and there are apps on the App Store that uses it (OpenVPN connect for example). You can try reverse engineering some of those app plugins (it's the folder with the .vpnplugin extension).
By the way, someone already did that and published the vpn plugin API to github: https://github.com/Smartype/iOS_VPNPlugIn/blob/master/iOSVPNPlugIn.h
Network Extension of iOS9 will allow custom VPN tunnel implementations and NEPacketTunnelProvider is probably what you are looking for.

You need to send an email to apple to get access to this function.

We required to send a word from one mobile device to another using wifi-direct. The wifi-direct, wifi-discoveryservice samples given in android sdk shows its usage with MainActivity. As we have app with multiple activities and from selected activities we need to send particular word to another device on wifi, we are looking for a simple 'SendWordWiFiService' approach.
Any related input in this regard is awaited. We are struggling for last 1 week trying to implement wifi-direct, wifi-discoveryservice in a project having multiple activities. But no success.
You need to use Sockets. If you haven't done them before, I suggest reading this as it got me started. Additionally you might find Oracle's documentation to be useful. In particular, you may want to read up on of using threads to run server sockets.
The steps you need to take are:
Discover peers using Wi-Fi Direct
Make a peer connection between decies (NB: Be mindful of who the group owner is once this is done, if you're application needs to differentiate between a group owner and a group client(s)).
Once the peer connection is made, sockets can be set up between the peers for the transfer of data streams, ie sending words in your case. You might find it most logical to set your Wi-Fi Direct GroupOwner as the server socket, and your GroupClient devices as a client which connects to the server.
I hope that helps.
