Im building a location based application, where in i use CLLocation to get users device location.
But my question, Is it possible to get users current/last know location from other apps in device which are already using Location services. So i can save the battery of iPhone?
Just a thought.
Not sure security issue?
Or is it possible?
Thanks in advance
No. Apps are sandboxed. You can not access info from any other app.
One word
NO
You can't access any info of other apps.
If you want to access any info, you have to jailbreak your iPhone, which Apple never allow.
From Apple,
Communication Between Apps Follows Specific Pathways
For security, iOS apps run in a sandbox and have limited interactions with other apps. When you want to communicate with other apps on the system, there are specific ways to do so.

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.
Hello all I am developing a extension app which will fetch-
The people you contact the most.
Most frequently used apps.
Any body have idea, How can I get these things.
Thanks in advance.
This is not possible. Your app runs in a sandbox, which means that it is very limited in how it can interact with the rest of the operating system. This is to prevent security vulnerabilities from apps snooping on a user's behavior. For more information on this, and to see what you can and can't do in the sandbox, see https://developer.apple.com/library/mac/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html.
i want to track how much time other apps in device are used by the user, i want track that time inside my app.for ex. i want track how much time user used the Facebook app, or WhatsApp or any other app.
is there any way to do this...please give any suggestions or example code or any other tutorials..
Thanks,
raki.
I think Apple don't allow tracking when you are out of your app, for tracking time and user activity in my apps, I use flurry.
You can track how long people use your app, sure. One popular way is via Google Analytics iOS SDK
For tracking other apps on the users device, that is simply not possible. You do not have access to other apps you have not developed yourself.
It cannot be done. Apple forbid apps trying to access things outside of their sandbox.
I am working on an App, in which i need to track the device using my App. I have gone through the "Find my friends" App that Apple has offered themselves. But, it asks user's permission if he wants to allow tracking his location.
I studied, an app named "Uber", they clearly track the cabs maneuver around the city. They also show the user, how far is that cab from the user, the possibility that might be here is "Uber" dudes could be using external GPS device and may be interfacing them with the user's device. Since, If I am not wrong.. Apple does not allow tracking devices.
But yet, I am in need to implement that kind of functionality in my App. I was wondering if it is possible ? I am aware of location tracking, my concern here is live GPS tracking.
Please point me in right direction here, Any help with be truly appreciated
I have a full working sample that shows how to track android, iphone, windows phone and java me phones. It also has the server software to put the location data in a database and allows you to view the location in real time and also store the routes to view later. Its MIT licensed:

Like everyone else I'm venturing into mobile app-development and I'm looking at different frameworks / languages. The ones that look most appealing to me are Phonegap, Corona SDK and Monotouch. Objective C seems to be a little too low level. I haven't done memory management for a long time and I'm not yearning to relive that experience. But if that's where I need to go to meet the client's need, I'll go there.
The client in this case needs location aware notifications in an iOS app.
A user story goes like this: The user is out walking the town. She's got her iPhone in her pocket and is listening to music via iTunes. As she walks into her local mall my app (running in the background) detects that she is in the proximity of a branch of her bank. My app also knows that the user has some errand to do at the bank. So my app interrupts the currently playing iTunes track, plays a notification sound and puts a notification text on the screen, telling the user that there's a bank office nearby and that she might want to do that bank errand now.
Could this be done with either Phonegap, Corona SDK or Monotouch?
MonoTouch supports all types of iOS location services (standard, significant location change and region monitoring) so yes, you can do it with MonoTouch.
Whilst Apple has started bringing in geo-location notifications with the Reminders app I'm fairly certain that it won't be exposed in the higher level frameworks as of yet.
Some good info here in the Apple developer docs
There are several ways to track the user’s location in the background,
most of which do not actually require your app to run continuously in
the background:
The significant-change location service (Recommended)
Foreground-only location services
Background location services
...
All are possible with MonoTouch. Pretty sure they are with PhoneGap also. Don't know about Corona.
