Can you send your currently location through the iPhone SDK to another iPhone and have them open up your location in Google Maps?
The only way I can think of is through text message, but I'm not even sure that would work.
Any ideas?
It'd be easy to set up a webserver to relay the message.
User 1's iPhone sends the phone's location to the server, which stores it in a database. User 2's iPhone periodically polls the server for the latest location of User 1 and displays it on screen.
You'd have to work out a good system of limiting which users can access whose data and so on, but otherwise it's a pretty straightforward project.

I am thinking to make my own app like Find My iPhone app . But I am confused that whether apple allow developers to have access to play with the security or is there such Apple API's that can help us to include features as in the above app. Any suggestions?
Well I just can't comment because of low reputation. But people must give a reason to down-grade a question. Its quite a valid question.
Creating an app like this is semi possible. Due to the fact that you are not allowed to keep running in the background, except for certain special cases. Such as Music or a guidance app (navigation apps)
Your app can register to receive updates from the GPS location and process them.
The problem is it will use your gps all the time.
The find my iphone app is a combination of wifi location/sim card location/gps location.
It uses a combination of all these items which it has to keep track of your location as close as possible. Now back to your question, the fact that you cannot keep running in the background, will mean the app needs to stay open all the time (open I mean running, not necessarily onscreen). Not like the application from apple itself, which of course is allowed to go outside these developer restrictions.
The APIs exist for you to create the main functionality of this app. Core Location and APNS
When use A is looking for the location of user B, A would tell a server that it needs user B's location.
A push notification could fire up user B's app, at which point...
User B's location services would kick in, in the background,
Send this information to your server
Then update user A with another push notification.
I want to find iPhone devices/device tokens within a specific radius from particular location.
For example : Within a 25 K.M. of radius from Sydney,i want to get iPhone devices tokens.
I am working on ASP.NET MVC2 for this.
Let me know,if is there any API for that?
Thanks,
You are only able to get details for devices that you 'know' about. Your app will need to log unique IDs for each device, and your app will need to log known locations for devices. It's then up to you to look up, from your central database, the details of the devices within a certain distance. iPhones can update significant location changes when running in the background but it's up to you to track devices and accept the limitations that that data may not always be correct. eg. If a user falls outside connectivity then you will still have an old location logged for that user.
I'm not aware of a single API that offers this services, if you're coding it then in your app you will need to register devices identifiers and location information to a central server. You will also need to create the lookup to query your data to find devices within a location. I am guessing that you might want to send push notifications, in which case your app will also need to register for notification services too.
There is no way for you to discover devices that don't have your app running and you also do not know who the owner is.
I was wondering if it possible to create an application that will send my 9 year old's iPhone location let's say each 30 minutes, even when the iPhone is not active.
If not, then is it possible to send it each time he uses his phone?
Why not using an existing solution?

See find my friends - it has also parental restrictions. This is excatly what you want.
You're probably looking for startMonitoringForReigion:desiredAccuracy:. This function will allow you to set the iPhone to notify your app anytime a defined boundary is crossed. When you receive this notification, I believe you can send that info to a server or wherever.
That said, if monitoring your child's location is what you want, you'll have great luck with the Find My Friends app from Apple.
I’m developing an application for iPhone that require server to be always aware of the user location. Does iOS have a feature whereby application (or iPhone device) keep reporting it’s location to external server?
Take a look at the "Tracking the User's Location" section in the iOS App Programming Guide. It tells you how to retrieve location data in the background. In this case, you probably only want to get significant updates.
You should be able to use startUpdatingLocation, then do whatever you want (e.g. a POST request) in the delegate.
We are developing an enterprise application .The phones are connected to a Wifi router. The objective is to trigger an alarm if the phone moves out of the secure area .. (outside the building)
What is the best way to check if the iPhone is always inside the building .
some of the options we tried are
1.using Wifi(continous ping to wifi network),if not trigger an alarm .
2.if coordinates change (using GPS)
Are there any other means to achieve this .
You can use Location Services in iOS 4 (with the background location feature) to determine when the phone has moved to a different location.
#indragie's idea of using Location Services is a good one. If you can be sure that the WIFI SID isn't going to change, you could probe to see which access point the iPhone is currently associated to. If you are going to ping, then a better approach is to make the system service agnostic, and simply issue an HTTP query on a regular basis to your enterprise server. The server can then have a policy language on it declaring acceptable access points (from a variety of metrics). This might be set up to allow people to take their iPhones home.
Your best bet is GPS as the phone will not be able to find its location if you rely on WiFi and the device is not connected to a WiFi network.
Check out Apple's documentation for Location Awareness capabilities here http://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/LocationAwarenessPG/CoreLocation/CoreLocation.html
You will be able to track "significant" or standard location changes in the background, details can be found here http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html#//apple_ref/doc/uid/TP40007072-CH5

This might be of interest to you too - http://longweekendmobile.com/2010/07/22/iphone-background-gps-accurate-to-500-meters-not-enough-for-foot-traffic/
It depends on what you want to do. Just to let the iPhone user know that he/she is moving away, using Location Services is good enough.
However, if you want to have a server that makes sure all the devices are within range, then it's more complex because your application may get suspended without a notice from a background state; in other words, you may not be able to catch the moment when your application terminates and take appropriate actions. Therefore you are going to need a heartbeat system like pinging to the server in this case.
