Is it possible to use Core Location / GPS without any internet connection / disabled cellular network?
I need to know if my iOS device (iPhone, iPad, iPod touch) need internet to be upadted the current location or if the GPS will do standalone, I want to know because my iPad will not update the current location without any kind of internet, and I want to make sure if true or false, or probabbly bad GPS location or something.
Thanks, I’m just using CoreLocation without MKMapKit.
You are halve right about the iPad, all devices that have 3G or 4G support will also have a full GPS receiver. Thus they do not an active internet connection to get a location.
On the other hand if your device has an active internet connection ti will able to give you a location quicker with triangulation of wifi and cell tower information.
You will first receive this location while the device tries to get a more accurate location via GPS.
