I am new to iphone development.I want to know that is there a framework or method to get the gps location of another iphone if the application is installed in both the iphone.
If there is any method can u please help me to sort out this
thanks in advance?
I agree with James, thank god it is not open in that anyone can see where anyone is via a single method, but I did create a solution that does this as a test app and it was not to difficult.
The frameworks that I used are Core Location to get the GPS coordinates, Foundation Framework to share the information with a web service using NSURLConnection, MapKit to map the coordinates, and the open source SBJson encoder/decoder.
I then created a PHP web service that enabled users of the app to register and choose who they would share their location with.
Then once per minute each instance of the app that is active would send its coordinates to the web service and then download any coordinates of other devices that it is allowed to see.
If I published this app, I would probably provide an option to chose the update frequency to conserve battery life.
Two free apps that also do this, that were created by Apple, are the Find Friends and Find iPhone apps.
If you are interested in creating something like this, check out the LocateMe sample code at developer.apple.com.

I am a beginner iOS developer and I am trying to build an app which tracks the users SMS (Number) and Call data (Minutes/day) only but have no clue which framework to use. CoreTelephony is of no use as per my knowledge. Any help would be appreciated!
Call Statistics and SMS Statistics are handled by the cell carrier, but are also recorded by the phone and are visible in the settings application. However, there is no way for your app to access this information (as far as i know). It would be a privacy concern and probably won't ever be available. Im sure there is a way to do it on a jailbroken device, but it sounds like thats not what you want. What exactly does your app do?
I know there is the core location sim project, however that requires new headers and your app to use them to override the builtin Core Location classes, but is there a way for an app to supply location information to the iDevice (iPhone, iPod, iPad etc) so that apps you installed may get the location information from them?
ie I have written an app to listen to another GPS device, get location information and I wish to supply that data to other apps on my iPad that rely on the standard CoreLocation interface.... Can anyone point to any docs available? (I don't want to use anything that Apple will block because it's based on hidden/undocumented APIs, nor do I want to rely on something that will require jailbreaking the phone/pad/pod etc.)
Working with iOS 5.1 and above...
Thanks in advance,
Michelle
It is not possible to override the installed Core Location hardware/software stack and supply your own values to all other apps' CLLocation calls.
I want to create an app that allows a user to find the nearby other users location using GPS coordinates who are Logged in to the same app .Also it can be track the location of the devices(Logged in to the same app) which are moving in a car .
Can someone give me an overview of how I can accomplish this. is there any free API available to accomplish this task.
Danielbeard is correct - you would need to be continually storing/updating locations on a server somewhere. Your app does get some running time when it is in the background, but I'm not sure it would be enough to run the web traffic that you'd need.
Check out this post: Running app in background and send frequent http request
And check out the multitasking guide here: Multitasking Guidelines
You can also look at Push Notifications. Hopefully this helps.
In iOS7 MultiPeerConnectivity was introduced to find near by applications, so if you have a coffee shop and someone walks by or in they could get the latest deals, or, you walk into a room and the music changes to what you like as your device exchanges information with another.

I am currently developing a location based iPhone application. Is there any way to test the app other than taking the iPhone to different places?
Thanks
Yes, you can.
Try this: http://www.vimov.com/isimulate/
(...) With iSimulate installed on their iPhones however, their multi-touches on the iPhone (which gets interpolated for the larger iPad screen), the movement recorded by the accelerometer, the location and orientation captured by the GPS and Compass, all get wirelessly sent to the iPad Simulator, so they can develop virtually any application they want, before the iPad is itself released!
Even though an answer have long been accepted for this question I'll still chime in with some additional information on the topic.
The kind folks at FutureTap have mad the FTLocationSimulator available for free at GitHub. It allows you to prepare a test route using for instance Google Earth, and then have the simulator feed these coordinates to your app.
I've written a blog post about how to use FTLocationSimulator to easily switch between multiple routes during testing of the location features.
i want to create a application which sync my iPhone contacts to my server and vice-versa.
i read a article on google Get Google Sync on your phone . i want to this type of feature which directly update the contact without user interaction (however one time setting is desired).
any body have idea how the google sync work .
Please advice me that how can i achieve this task. any suggestion and link is greatly appreciated
I think it's important to separate the two overlapping approaches in your question.
Firstly, Google Sync is essentially a way to use Microsoft Exchange protocols and to setup a Mail / Contact / Calendar profile on an iPhone. The iPhone OS supports this feature, not an iPhone App in the App Store. Google Sync leverages this fundamental capability of the phone by exposing the data (mail, contacts, calendars) via these known protocols. If you want to expose data in this way to your users, setup a Microsoft Exchange server and ask questions on serverfault.
Secondly, there are iPhone apps. iPhone apps sold in the app store are not currently allowed to run in the background. This means you can't emulate functionality like iTunes or Mail where your music plays while you are browsing the web, or mail checking is done while you are playing a game of Mini Squadron. If you want this backgrounding capability, file a bug/enhancement with Apple.. However, you can interact with iPhone contacts (Address Book) via the API.. You can also of course "re-invent the wheel" and expose the data however you like via the internet, and consume that data from a custom iPhone App with the one caveat that users would need to actively launch your application to get to this data and it would not be integrated with the built-in iPhone Calendar, Address Book or Mail applications. Some good examples of that are some of the music community apps that have messaging systems built into them. Presumably that is all being done with web services.
EDIT: It is also worth mentioning that should you go the "iPhone App" route, you should at least consider if push notifications are right for you, and if so how you will handle it.
Have you seen the API-Docs?
http://developer.apple.com/iphone/library/documentation/ContactData/Conceptual/AddressBookProgrammingGuideforiPhone/100-Introduction/Introduction.html
Next there is an application I use called Funambol - it is a sync4j Server/Client. They have an open source application to sync contacts on the iPhone. Source is somewhere in their repository, informations here: http://forge.ow2.org/scm/?group_id=96
As slf told you your application must run in foreground. This may limit you.
Good luck & best regards,
Florian
The 3.0 SDK will allow your application to read contact data on the phone.
Web services will allow you to publish that data to your server, and receive updates.
You may also want to use coredata to store a hash of all contact data so you can tell what is new / updated and just send that data to your server.
