Thanks Kerri for your response.
Here is a code snippet which we have used on a button click. This gives user's
current Latitude and Logitude and using Google Or ArcGIS api we reverse Geocode
to get the address. However I have tested it and we don't get the current
address rather the address where I visited last. Seems like Geolocation API is
not providing the current latitude and longitude immediately.
Just so you know I have tried the combination all the attributes -
EnableAccuracy, maximumage etc and nothing works. Again this issue is only on
IOS Iphone App and our user will be on move constantly. Tried both-
GetCurrentLocation and GetWatchPosition.
navigator.geolocation.watchPosition(showCurrentLocation,
locationError, { maximumAge: 0, timeout: 30000, enableHighAccuracy: true });
Your help will be greatly appreciated.

if (!options.timeout) options.timeout = options.maxWait; // Default to
maxWait
options.maximumAge = 0; // Force current locations only
options.enableHighAccuracy = true; // Force high accuracy (otherwise, why
are you using this function?)
watchID = navigator.geolocation.watchPosition(checkLocation, onError,
options);
timerID = setTimeout(stopTrying, options.maxWait); // Set a timeout that
will abandon the location loop
};
Your help will be greatly appreciated.

> Key: CB-12251
> URL: https://issues.apache.org/jira/browse/CB-12251
> Project: Apache Cordova
> Issue Type: Bug
> Components: CordovaJS, iOS
> Affects Versions: 4.1.1
> Environment: IPhone, IOS
> Reporter: Anshu Raj
> Priority: Critical
> Labels: features, geolocation, mydistrict
>
> Feature: We have created a Mobile App using PhoneGap and Corodova Plugin to
> get a constantly moving user's current location. As soon as he stops, he will
> perform an action in our App which will send his current location and we
> convert it into Address using reverse geocoding. We then show the history of
> user's visits.
> We are using GetWatchPosition and GetCurrentLocation to implement above
> feature.
> Issue: We are not getting user's current Latitude and Longitude rather we get
> their last Latitude and Longitude where he last visited. Hence user's visits
> is wrongly registered based on where he was at that point of time. Somewhere
> the API is not sending us the latest Latitude and Longitude.
> Above is working fine in Android and we are getting updated Latitude and
> Longitude
> Please help!
