Convert coordinates to address - ios

I want to know how you convert geo coordinates into an address. I have already tried the CLGeocoder class but I have no idea how to convert my data.
Thanks

You need to use the CLGeocoder Class to get a coordinate to physical address lookup. The command you are looking for is reverseGeocodeLocation:completionHandler:. You pass your CLLocation location object containing the coordinate data to look up.
Read more about it in Apple's CLGeocoder Class Reference.

Get GMSPlace from longitude/latitude coordinates?

I looked at the API here, but it only mentions that you can get the GMSPlace for the user's current location. Is there any way to create my own custom GMSPlace object or get the GMSPlace for the lat/long I want? I looked at previous solutions but didn't find anything.
As per Google's docs:
Represents a particular physical place. A GMSPlace encapsulates
information about a physical location, including its name,
location, and any other information we might have about it. This
class is immutable.
Apparently there is no way to make your own GMSPlace object from the coordinates, nor there' a method that Google's SDK provide.
What I did before, I search for places, the one that Ajay user above discussed.
So the process is:
Get coordinates.
Reversegeocode to get the string address.
Search the string address using the GooglePlaces autocomplete.
From the first result in #3, the placeId is used to get the GMSPlace object using the lookUpPlaceID method.
Beware though that sometimes it returns a wrong address. I've tried it.
GMSPlace is a class provided by Places SDK which provides information about a specific place. You can not create your own custom object.
EDIT: To find a place other than your current location it provides Autocomplete api which automatically return location suggestions while users type.

How to get object GMSPlace by longitude and lattitude and without GooglePlacePicker?

I have coordinates for the place on map. Is it possible to get GMSPlace object using some method (without GooglePlacePicker) like currentPlaceWithCallback with custom longitude and lattitude?
with out GooglePlacePicker, you can use CLGeocoder!.

How to show multiple route IOS Mapview

I am creating IOS Application map based application in my app I like to show the route/path between source and destination and also I have done that but I will show only one route/path. I like to show all the possible path between the source and the destination like google map. To illustrate my idea I have added the screenshot I like to show path like this. Is there is any sample for this?
Thanks in advance
Follow these simple steps :
Get Two Input locations.
Use the method -geocodeAddressString: completionHandler: of Geo Coder class (from Core Location Framework) for getting the coordinates for the given location string.
Use MkPointAnnotation object for creating annotation on the locations in map.
Send request to the google API for getting the Direction between two locations.
As of the google API Response (Available in both JSON & XML) You would have overview_polyline object, which has the array of location coordinates. But they were encoded, you have to use the correct decoding module to get the latitude and longitude.
With the decoded location coordinates you can create the poly lines using MKPolyline instance method. MKPolyline *polyLine = [MKPolyline polylineWithCoordinates:coordinates count:[overlayPoints count]]; [mapView addOverlay:polyLine];
Now the polyline have been drawn over the map still it will not be visible as the final go we have to override the -viewForOverlay method for displaying the poly line view.
If you still have any confusions then you can always check some Tutorials.

iOS CLGeocode address dictionary

I am trying to use CLGeocoder to reverse geocode an address and want to create an address dictionary programmatically to use to geocode with. How can I do that? I can't find anything on it! Thanks.
The docs in the CLGeocoder header file give you the info you need:
// geocodeAddressDictionary:completionHandler: takes an address dictionary as defined by the AddressBook framework.
// You can obtain an address dictionary from an ABPerson by retrieving the kABPersonAddressProperty property.
// Alternately, one can be constructed using the kABPersonAddress* keys defined in <AddressBook/ABPerson.h>.
- (void)geocodeAddressDictionary:(NSDictionary *)addressDictionary completionHandler:(CLGeocodeCompletionHandler)completionHandler;

Getting a place object for user's location using twitter4j

Twitter provides an API for getting a place object for any given location. As per twitter API documentation at https://dev.twitter.com/docs/api/1/get/geo/search :
"Given a latitude and a longitude pair, an IP address, or a name, this request will return a list of all the valid places that can be used as the place_id when updating a status.".
API returns a place object. I am specifically interested in getting the bounding coordinates for that place which can be a Point or a polygon which is included in place object. I will then use this to check if user's location lies within some other location say New York.
Now, for any user one can fetch his profile using twitter API. API returns a json object which contains user's location which is basically a string e.g, "San Francisco, CA". This location can be passed to geo search api mentioned above to get coordinates for the polygon which defines a user's location.
I am using twitter4j library to do the same. Method 'searchPlaces()' corresponds to
/geo/search API of twitter and takes a GeoQuery object as argument. However, GeoQuery object has only two constructors which take GeoLocation i.e, latitude, longitude information or ip address.
https://github.com/twitter/twitter4j/blob/master/twitter4j-core/src/main/java/twitter4j/GeoQuery.java
As can be seen in GET geo/search API, all parameters all optional. However, providing only two constructors in GeoQuery class forces one to provide either latitude and longitude values or ipaddress. What I have instead is the string for user's location from his profile.
Can someone please help me out with why there is this disparity between twitter4j and twitter API. Also, can someone suggest some other way to find if some twitter user is from New York.
PS: Any attempt to geocode user's location to get lat,long also requires GeoQuery object which again needs lat, long and I don't seem to be able to figure out how this can be done too.
Thanks in Advance.
I encountered this as well. A workaround is:
GeoQuery geo = new GeoQuery((String)null);
geo.setQuery("New York")
