In my app I want to set current time.I know we can get it via device but it became user specific. If user change his device time then i am not able to find current time in my report.So is there any API which can give me current time based on location or LAT-LONG.
Please share if any one has idea about this.
Thanks All.
The WorldTimeEngine webservice offers an API that converst geolocation coordinates into local time.
Edit: there's this AskGeo web API also, it seems to be free and provide time information.

I am trying to calculate how many miles away the user is from another user. Like on Tinder.
I am using Firebase to store all of the users data related to the app.
What would be the most secure way to do this without storing the actual users current location?
You need to get the current location, and after calculating the distance or after the user logs out, delete the location from the database. That is the only way to do it.
Note that this will work only if both users are online at the same time.
my girlfriend and I have some cool statistics to provide for an uber user, but without start and end location, is basically impossible.
Given the current API, that's what we tried:
GET /v1.2/history: provide some information, but related to location, only the city where the ride happened
GET /v1/requests/{request_id}: give location only for in_progress rides
GET /v1/requests/{request_id}/map: here was the closest place we got. After some element inspection we figure it out that there is a json nested in the html that provide this information. But again, when generating maps for each ride, most of them gave us this error: (that based on answer that we found in another question here, its because maps are available only for a couple of days): {'code': 'conflict', 'message': 'Unable to generate map for trip "6a31e621-2c6f-4422-ac74-e9f382b346c5"'}
There is some way to retrieve this information or has someone successfully done this?
I mean, I don't know if they hide this information because privacy concerns. But, during some time we have the information. It's all about timing, If this is because a privacy concern, why they provide this temporarily, then, hide. If anyone know about the way that it works (you can make sure they search more than us about this), they are already collecting this information.
We do not currently provide start and end location for all trips via the history end point. Currently, we only provide start / end location for in progress trips. Your understanding above is correct.
I am in the process of building an app, for the record I am using the code from the ECSlidingView controller. I would like for my app to use the GPS to pull data from my web interface letting the user know that they can do certain things at a given location. So for example, I have a user go to a store and lets say I want them to make a payment at that location, it will given them that option. Or if the store doesn't offer payment through the app, I disable that. What would be a good way to go about this?
You could try using CoreLocation but you might have trouble getting accurate location inside (it will most probably use wifi or cellular info so the accuracy might not be what you expect). Then, when you get the location, issue a request to your service passing latitude and longiude you receive from CoreLocation. There, you should search by location to retrieve possible matches - consider returning muliple store infos for nearby stores due to the accuracy issues.
I want to know how facebook gets live updates from the server. Did some analysis and found it use some sort of channels which keeps on dying and generating like
0-143.channel.facebook.com
Please give your ideas what it could be.
Thanks

Facebook uses javascript to pitch an ajax request to their servers at a specified time frame say like every 60 seconds or so and updates your UI accordingly if there's been updates.
get started http://jquery.com/ and more specifically http://api.jquery.com/jQuery.ajax/
Ok... maybe forbidden by Apple, but assuming this is permitted. What would be the best way to get the current location (not difficult) and posting it to a web service (also not much of a challenge). The app is for an artist who wants people to see where he is at the moment. Personally, I wouldn't want people to know where I am 24/7 but that's performance art I guess. An exact location is not wanted but a town or area would be preferred. I could modify the string when it gets to the server and make it more vague by rounding the LOG and LAT.
The app the fans would use would retrieve his current location from the server and update the map view with a location.
I suppose one way would be for him to find out his coordinates and post that to a web page but I'd like it to update automatically.
A response with code is not necessary, just a general opinion on methodology/advisability would be appreciated
I would probably give him a webpage to go to that records his position every time he visits. It would be a private URL, and perhaps use some lightweight authentication. For versatility, I'd record the exact position in the database (in case he changes his mind on how it should work later on). However, you could use an external service or another purchased database with zips or city information with lat/lng data, so you could just provide users of the client app with his general vicinity rather than exact location.
The alternative would be to give him an ad hoc app that does the same thing, but putting together that location recording webpage would be a much simpler process. Could be handy for other things, too.
Here's a little writeup about getting location from mobile Safari, just as a reference: http://mobiforge.com/developing/story/location-iphone-web-apps
Why wouldn't you just use google latitude and read out his status?
I think this should really be done as a web page web-app. You can get coordinates from the device through mobile safari and you can skip the app approval process. You can also set it up so it runs fullscreen on his phone and he won't know the difference. You can also put a password on it.
There is a good chance it would not get approved as a regular app.
You can always meta refresh the page to keep it updating.

"Artist" must log in to his application (thus insuring that he want to share his coordinates with your webserver), then you use CLLocationManager to get his coordinates and make a reverse geocoding using Google Maps API to get country and city for given coordinates.
Can't see anything special about it :)
