Is it possible to simulate a location on iOS Device, say I want to simulate London on the device while I am sitting in Oxford?
Thanks.
Yes, It is possible to simulate the location on device in debug mode. All you need is to debug your application on device, and then enable the location from debug menu.
Check this link...
https://developer.apple.com/library/ios/recipes/xcode_help-debugger/articles/simulating_locations.html
You can create a GPX file with the desired location/coordinates and you can enable it from the debugger or from the Project scheme select run/options/"Allow location simulation".
After you have this enabled and your device connected the location simulation will work on the device to till you reboot it.
A good article that explain this can be found here: https://blackpixel.com/writing/2013/05/simulating-locations-with-xcode.html
Maybe this project can help: https://github.com/futuretap/FTLocationSimulator
It simulate location sending fake data to the coreLocation.
I have created a QR Code which displays a map of our mountain bike trails. First off I'm not an Apple guy, so I'm not sure what needs to be done to make this cross platform Android and Apple. The QR Code works correctly on Android. When scanned it opens up the kml file in Google Maps and displays the map and your GPS location.
When I scan this with an iPhone is displays the map and asks if you would like to accept sharing your current location. I accept it but it won't display my location. Is there something I need to do to make it work on Android and Apple, or any other suggestions. A little frustrating. As I look at the logs majority of the users what scan the code are iphones so I need to get it to work on them.
Update: here is a screenshot of the iPhone.
It should also have your gps location like this
Thanks for the help!
On Android, the default Google Maps behavior appears to be to show to the current location up front.
On iOS, however, it seems that Google Maps decides that the user can hit the location button if they want thier current location.
As far as I'm concerned, I side with Google.
Also, it could be that you need to try some different QR scanners - some might automatically show the location, some might decide to conserved resources instead.
P.S. To take a screenshot on iPhone, press the lock and home buttons at the same time :)
I need to demo my app to my supervisor. At the minute I have set all the testing up so that it works with the highway drive in cali. When I demo it I will be in an office (stationary) so the real location data for the phone wont show the demo results at all.
Is there anyway to make the iphone do the city drive? - When its running natively i.e. not connected to the machine.
There are various CLLocationManager simulators on github that you could include in your demo build, such as the CLLocationManager_simulator here.
Alternately you can set up your apps to record location data to a file and then create a CLLocationManager simulator that plays back the file. With that testers can record test drives and then devs can play them back in the office to debug or examine what happened or retest with new builds.
If you don't mind using the Simulator to demo it, there's simulated location available. Look in the Simulator menu under Debug -> Location.
I'd like to test what happens if my app can't get the location coordinates. Is it possible to disable the location service in the simulator, like on an iPod Touch with WiFI turned off?
I still don't have my iPhone Developer Program certificate, so I can't test it on my device.
Thanks in advance!
You can disable the location services in the simulator;
Run your app through xcode so the simulator opens
Stop the app via xcode (this should leave the simulator open)
Open the Settings app in the simulator window
Privacy > Location Services. Disable Location Services
Run your app again, location services should be disabled
Hope it helps!
As a workaround you can try to simulate update location failure by constructing NSError object with appropriate values and calling corresponding CLLocationManager delegate didFailWithError: method manually.
To my knowledge, you can't disable the location service on the simulator.
The approach that I normally use when using the location service is to build a simple wrapper class arround NSLocation tailored to the needs of my application.
In this wrapper, you could easily pretend that the service is not working in the simulator. For example, it could have a "isEnabled" method that returns false on the simulator with a compiler define like (#if TARGET_ IPHONE_SIMULATOR)
**Disregard this. This works around the MapKit. Check comments below.
Disconnect the computer from internet connection. How to.
EDIT: You can test the code from this site that can be downloaded here
With AirPort on, you get the map. With the AirPort off you get a blank squared view.
Location Manager Error : Operation could not be completed(KCLErrorDomain error 0)
Why does this error occur?
This error occurs if you have Scheme/Edit Scheme/Options/Allow Location Simulation checked but don't have a default location set. I'm sure there are other causes as well though.
UPDATE
THANKS TO Ben Marten
You can make it permanent using these steps in XCode:
Product > Scheme > Edit Scheme
Click Run .app
Option tab
Already checked Core Location > select your location
Press OK
Besides that, even if you are not connected to wifi, you can set a location in simulator through top menu items Debug>Location and to make it permanent follow steps above
I just had this problem. Took me a while to find the solution, which is only loosely related to the previous poster's answer.
Airport (WiFi) must be on for CoreLocation in the iPhone/iPad Simulator to work. I was connected via Ethernet so CL didn't do anything in the Simulator. Turn on Airport in your Network Settings and try again. You can change the order of your network interfaces by dragging Airport below Ethernet if you want to continue favoring your wired connection over your wireless...
From the API docs:
CLError
Error codes returned by the location
manager object.
typedef enum { kCLErrorLocationUnknown
= 0, kCLErrorDenied, kCLErrorNetwork, kCLErrorHeadingFailure } CLError;
Constants
kCLErrorLocationUnknown The location
manager was unable to obtain a
location value right now.Available in
iPhone OS 2.0 and later. Declared in
CLError.h.
kCLErrorDenied Access to the location
service was denied by the user.
Available in iPhone OS 2.0 and later.
Declared in CLError.h.
kCLErrorNetwork The network was
unavailable or a network error
occurred. Available in iPhone OS 3.0b
and later. Declared in CLError.h.
kCLErrorHeadingFailure The heading
could not be determined. Available in
iPhone OS 3.0 and later. Declared in
CLError.h.
So this means the location could not be determined.
I would guess the most likely cause is that the location manager is using WiFi to triangulate the location, and the database doesn't cover the local networks. That apparently can be fixed by the user if they go here.
However as I noted I have also seen this occasionally as a transient error when running a location based program in a location where the WiFi location stuff normally works.
Lastly I guess it is possible to see this error if there is some kind of hardware failure.
1) check that you actually have a valid WiFi and 3G connection
if you do then
2) go to settings and reset your location services
3) reset your network settings
If you got this in Emulator then do following
Debug > Location > ✓ Apple
This error is thrown when Location Manager is unable to get location information immediately. I found that this error was occurring when startUpdatingLocation method was called. For me, this was happening on iPod but not on iPhone. That makes sense, since, iPhone has more ways (like cellular network) to get location information and is able get a quick estimate on the location whereas iPod takes more time which caused this error to be raised on iPod.
Since, when this error is thrown locationManager:didFailWithError: delegate method is called, one can handle this specific case in a conditional statement by matching "[error domain]" and "[error code]" from the error object passed to this method.
The exact reason what I have found is there is a conflict occuring in the location simulation in both the ios simulator “Debug settings” and in the xcode settings “Edit schemes”.Ensure to set you default user location in any one of this and mark the other to None solved the problem hope this might help for sure.
InXcode:
In iphone/ipad simulator:
You can add your own list of locations to Xcode to test your applications with.
From within Xcode select the menu Debug/Simulate Location and you'll be offered:
a. "Don't Simulate Location"
b. 12 example locations
c. "Add GPX File to Project..."
Select "Add GPX File to Project..." and select the GPX file you've created.
Go to Xcode project >product>scheme>edit scheme>chek location simulation>set your location> and run app again Hope it will works !
Thanks to this article (https://possiblemobile.com/2013/04/using-xcode-to-test-location-services/) I got a hint to look at the data on my custom GPX file and there found the issue.
Some GPX files you might get from different sources might have the following elements indicating the different coordinates in specified path. This wont work with Xcode's Location Simulation.
<gpx>
...
<trkpt lat="" lon="">
<ele></ele>
</trkpt>
...
</gpx>
What you should do is find all occurrences of the "trkpt" element and replace it with "wpt" in your favorite text/xml editor. The end result should be something as follows:
<gpx>
<wpt lat="" lon="">
<ele></ele>
</wpt>
...
</gpx>
Hope this helps! It certainly helped me.
This error occur while you run your program ,but you simulate location after you run the programe.
I get a method :quit your simulator and restart it ,then set your simulator location before you run the programe,and it works for me .
Hope this helps! It certainly helped me.
thanks...
all of this didn't work for me.. what worked for me is :-
set the location from the simulator to none then change it back to custom location while the app is running.
All of the suggestions didn't help in my case. What helped was to uninstall the app from the simulator device, reinstall it and allow it to access the location (in the settings app).
If you are getting this on the device, chances are you did not ask for or the user denied the permission to gather the location.
