I do not want GPS information to be incorporated in the pictures/videos taken by our app, I could not find any api to disable GPS location information while using camera. I know user can enable disable it by going in settings etc, but I want to turn off GPS only for my app automatically so any camera (video/picture) should not use GPS at all.

Because Android models of Android 10 and above restrict the third-party background to continuously obtain location information, if we use Huawei's own SDK positioning interface, can we ask whether we run the positioning interface in the background to obtain location information while the phone is sleeping. If the mobile phone is in the sleep state, the current location information is obtained at intervals of 5 minutes to achieve the effect of tracking or tracing the location of the mobile phone.
Huawei's positioning SDK supports continuous acquisition of location information, you can refer to this document for development https://developer.huawei.com/consumer/cn/doc/development/HMS-Guides/location-guidev4#h1-1576578169417-0
I want to show gps coordinates in the Label, is there any default API which can observe/detect that GPS location is changed,so we that I should be able to take and show new GPS location in the label.
You should take a look the Location Awareness Programming Guide.
in my app a user can fetch the coordinates of his/her location by either using GPS or through Forward geo-coding. the thing i want to ask is, how can i detect that the device being used has hadware GPS support using horizontal accuracy values.???
thanking you in anticipation....

Is it possible for an iphone app to continually send gps device location updates to a remote server, so the device could be "pin-pointed"?
I understand i can get the gps cords and get the app to continue to get them in the background, but im unsure about being able to send the cords to a webservice when in the background mode or if apple would even allow me.

According to the apple documentation, I think this should be possible.
But you will not be able to use real GPS device. When running in the background you will only receive major location changes. Which are detect when the user travels into a new GSM cell.

For the sake of this question, assume I plan to build a Google Latitude client app for iOS 4.
my app needs to upload the user gps location every two minutes, and also download the user friends locations. - in the background!
my app can't wait to be woken up by the OS on cellular tower switches (because they may only happen after 2 KM, while my app needs constant gps updating), so I understand I can create a thread, similar to the ones GPS navigators use, to run in the background.
I have no knowledge in iPhone programming, I just need to know if my app is feasible.
Will I be able to access the internet from within the background thread (and upload the user gps location), or is it restricted to only sampling the GPS location.

Will Apple approve such an application, or is this type of use forbidden? because my app isn't realy critical such as a gps navigator
Thanks!
As Don said, iOS will send location events to apps that support it. From there, the app can do what it needs to do with the location event.
Background apps can register for one of three options:
Significant changes only: a low-power way to track location that only wakes the app up when there's a "significant" change in location
Standard location services: compatible with all iOS devices that can use location services, allows you specify change in distance, and works in background. However, if the app has been terminated or suspended, iOS won't attempt to relaunch the app.
Continuous location services: allows the program to receive continuous location updates and iOS will not suspend the application when sent to the background.
More info: Executing Code in the Background and Location Awareness Programming Guide
If you take a look at Executing Code in the Background, Apple provides guidelines on what multitasking-aware apps should and shouldn't do.
You will receive the locationManager:didUpdateToLocation:fromLocation: message in your app. In there, you can do whatever you need to, although you should not update the UI or use Open GL if your are in the background.
