I want to write location tracking app like " find my iphone " that runs in foreground,background and even terminating ( not running) . Location will be sent to my server periodically time. I have searched in google and read many many documents,tutorials comments, codes about this topic. Then I have found this tutorial . But in this tutorial, location is sent to ".txt" file in foreground and background not terminating ... I mean, when the app is killed, it is not relaunched in the background to send location ".txt" file .. So I have added and updated some codes to send location when it is not

I just spent the last hour searching - thinking that there has to be an answer - and didn't find much, so I'm asking here. I'm trying to get the sample app Regions to trigger enter and/or exit regions updates via the simulator. I'm familiar with setting a specific latitude and longitude with Debug > Location > Custom Location but that doesn't seem to do much, although it does seem to work in the LocateMe sample app. At this point I don't know if the problem is a limitation of the iOS Simulator or of the way the sample app handles region detection (I'm still rather new to iOS). I've come across

Could you please give me example how to calculate current "speed", I'm working on my first simple app ala speedometer? I figure out to use didUpdateToLocation also I found that I need to use formula speed = distance / duration Is it right? how to calculate duration? The basic steps that you need to go through look something like this: Create a CLLocationmanager instance Assign a delegate with the appropriate callback method Check to see if the "speed" is set on the CLLocation in the callback, if it is - there's your speed (Optionally) if the "speed" isn't set, try calculating it from the

According to apple docs, significant location change should update location at least every 15min. I am indeed receiving updates when I move significantly, but not when the device is stationary. What is your experience with updates? Do they come at least every 15min? If GPS-level accuracy isn’t critical for your app and you don’t need continuous tracking, you can use the significant-change location service. It’s crucial that you use the significant-change location service correctly, because it wakes the system and your app at least every 15 minutes, even if no location changes have occurred,
