Get location name from Latitude & Longitude in iOS

Method with completion block:

typedef void(^addressCompletion)(NSString *);

-(void)getAddressFromLocation:(CLLocation *)location complationBlock:(addressCompletion)completionBlock
{
    __block CLPlacemark* placemark;
    __block NSString *address = nil;

    CLGeocoder* geocoder = [CLGeocoder new];
    [geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error)
     {
         if (error == nil && [placemarks count] > 0)
         {
             placemark = [placemarks lastObject];
             address = [NSString stringWithFormat:@"%@, %@ %@", placemark.name, placemark.postalCode, placemark.locality];
             completionBlock(address);
         }
     }];
}

This is how to use it:

CLLocation* eventLocation = [[CLLocation alloc] initWithLatitude:_latitude longitude:_longitude];

[self getAddressFromLocation:eventLocation complationBlock:^(NSString * address) {
        if(address) {
            _address = address;
        }
    }];

I'm giving you snippet which I'm using for resolving address. I'm including comment also at neccessary place to understand the code for you. Besides that feel free to ask any question from snippet if you get fail to understand anything.

Write following snippet in didUpdateToLocation method

NSLog(@"didUpdateToLocation: %@", newLocation);
CLLocation *currentLocation = newLocation;

if (currentLocation != nil)
    NSLog(@"longitude = %.8f\nlatitude = %.8f", currentLocation.coordinate.longitude,currentLocation.coordinate.latitude);

// stop updating location in order to save battery power
[locationManager stopUpdatingLocation];


// Reverse Geocoding
NSLog(@"Resolving the Address");

// “reverseGeocodeLocation” method to translate the locate data into a human-readable address.

// The reason for using "completionHandler" ----
   //  Instead of using delegate to provide feedback, the CLGeocoder uses “block” to deal with the response. By using block, you do not need to write a separate method. Just provide the code inline to execute after the geocoding call completes.

[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error)
 {
    NSLog(@"Found placemarks: %@, error: %@", placemarks, error);
    if (error == nil && [placemarks count] > 0)
    {
        placemark = [placemarks lastObject];

        // strAdd -> take bydefault value nil
        NSString *strAdd = nil;

        if ([placemark.subThoroughfare length] != 0)
            strAdd = placemark.subThoroughfare;

        if ([placemark.thoroughfare length] != 0)
        {
            // strAdd -> store value of current location
            if ([strAdd length] != 0)
                strAdd = [NSString stringWithFormat:@"%@, %@",strAdd,[placemark thoroughfare]];
            else
            {
            // strAdd -> store only this value,which is not null
                strAdd = placemark.thoroughfare;
            }
        }

        if ([placemark.postalCode length] != 0)
        {
            if ([strAdd length] != 0)
                strAdd = [NSString stringWithFormat:@"%@, %@",strAdd,[placemark postalCode]];
            else
                strAdd = placemark.postalCode;
        }

        if ([placemark.locality length] != 0)
        {
            if ([strAdd length] != 0)
                strAdd = [NSString stringWithFormat:@"%@, %@",strAdd,[placemark locality]];
            else
                strAdd = placemark.locality;
        }

        if ([placemark.administrativeArea length] != 0)
        {
            if ([strAdd length] != 0)
                strAdd = [NSString stringWithFormat:@"%@, %@",strAdd,[placemark administrativeArea]];
            else
                strAdd = placemark.administrativeArea;
        }

        if ([placemark.country length] != 0)
        {
            if ([strAdd length] != 0)
                strAdd = [NSString stringWithFormat:@"%@, %@",strAdd,[placemark country]];
            else
                strAdd = placemark.country;
        }

Where strAdd will return address using geolocation..

Enjoy Programming !!
