I am looking to get my Latitude and Longitude from my IOS device when my gps is not on or simply when in the setting the user makes the Location to NEVER.
In android I have done this. Since I am new to IOS development is there any way to find out the latitude and longitude .
Please ask for edit or do it if I have framed the question in a wrong way. Hope I have clearly mentioned the issue.
Any help into this is appreciated.
iOS only has the CLLocationManager available for get the devices location. The CLLocationManager uses all possible method to get the location of the deice.
It uses cellular triangulation and only later after it get a GPS fix will it pass these locations to your app.
There is no way to ask CLLocationManager to only use cellular triangulation. You might only get the location based on cellular triangulation and WiFi if you set the desiredAccuracy higher.
So you will always need to use the CLLocationManager which requires the users permission.
There is no other way to get the users location in iOS.
If the user does not give the app permission for location, you will not be able to get it from GPS or cellular.
You might be able to get an rough approximation based upon the IP address, but that will be far from precise.

I know we can access user's location using geolocation in iOS. I want to know what other ways we can access user's location off course with his permission. I also heard we can access user's location using network/Internet etc.
All geolocation of the device is done via the CoreLocation framework. The specifics of what method(s) used to determine the location is not provided through the framework. The position can be determined via WiFi proximity to a known AP, cellular proximity to a tower mapped by the carrier, or most accurately via the GPS system. Not all methods are available on all devices, obviously. Rather than knowing how location was determined, you merely request location within a desired level of accuracy, and the framework will call back and notify you of an update in position. The actual position is not guaranteed to be pinpoint accurate.
Im trying to create an app which is assigned to all staff in my company. Platform is ios. The function of this app is to detect the nearby staff indoor and data will be populated from internal DB.
Your app get the user's location using GPS and send each user's location to a central server, which would then send back map data so each user could see all the others. GPS doesn't work super well indoors though, so the other option would be low power Bluetooth, but that isn't very directional. Check out iBeacon.
Do not use GPS,it is not Accurate in door.
You may use some indoor location
Use Ibeacon- Based On BLE
There is a company called Estimote,their offer their Indoor location
SDK
Use WIFI based Indoor location
You may google more details, there are a lot details about Indoor Location
So the general idea is to get location information ONLY if it is from a GPS source (not WiFi or Cell-Tower). The reason for this isn't really important, for research purposes (and not my research).
If I specify the desiredAccuracy to kCLLocationAccuracyBestForNavigation, it should be using GPS to gather this information. Is it guaranteed, however, that it will use GPS?
I know you can also check the verticalAccuracy property for validity of altitude, which can only be valid if it is from 3D GPS, but does this guarantee that the rest of the information other than altitude is from GPS also?
I posted here on the apple developer program and got a response from an apple employee: https://devforums.apple.com/thread/264712
Even if it's guaranteed to /use/ GPS, it's not guaranteed to /only/ use GPS.
iOS's location subsystem does not provide a way for you to
pick and choose the specific location technology used to satisfy your
request. You will not be able to achieve this goal on the system as
its current architected.

I'm attempting to create a simple single-page website that answers the following yes or no question: is a specific iPhone on land?
To explain further, I want to track the iPhone of my brother who works on a tugboat to find out if he's on the boat or on land. Is there a way of syncing to his iPhone's GPS data? Perhaps through "Find my iPhone" or a similar app?
Thanks for your help.
On iOS you can access the GPS coordinate of a device using CoreLocation, specifically CLLocationManager. You can poll it for updates and you get back a CLLocation object that has your latitude/longitude. There may be another step you need to perform after this to see if a GPS point is on land or not, which I'm not exactly sure the best way to approach.
i need to get the current location of device and for that i used the GPS mode in blackberry and i succeeded to get but the GPS work outdoor under sky not under roof so maybe is there another way or another method to get the location indoor.
i tried with this sample code :

and also same result cant get location indoor its return nothing
wish is there any help and thnx for answer
Read again that link. It explains how to use Geolocation API, which is available starting from OS 5.0. The locations are obtained based on Cell info (OS 5.0) and also from Wi-Fi access points (OS 6.0).
UPDATE
Read this tutorial on how to use geolocation.
