litoarias/HACLocationManager

This class allows you to conveniently manage location iOS >8

HACLocationManager is written in Objective-C, very easy to use and effective class.
Requests are made using blocks. Its syntax is very comfortable and intuitive. Use singleton design pattern and its compatibility is complete with iOS8 or higher. This class is not for use as GPS, only for obtain user location in any moment and get geocoding and reverse geocoding.

##Usage

Requesting Permission to Access Location Services

iOS 8+

Since iOS 8 it is required to add NSLocationWhenInUseUsageDescription key to your Info.plist file. Value for this key will be a description of UIAlertView presented to user while asking for location permission. See Apple documentation for more info.

Basically all you need to do is to add single entry in your Info.plist file. Add key NSLocationWhenInUseUsageDescription, and select type String. The value you enter for this entry will be shown as text in UIAlertView presented to user first time you try to determine his location. In the end it should look similar to this:

Request permissions

To request permissions location, when you want independently to any operation. This request must always be performed before applying any other. I recommend do it in your AppDelegate.

[[HACLocationManager sharedInstance]requestAuthorizationLocation];

Instance class & set time out

You can configure time out for updates in request, for default it's 5 seconds

HACLocationManager *locationManager = [HACLocationManager sharedInstance];
locationManager.timeoutUpdating = 6;

###Obtain user location Is obtained by locating blocks, based on the location and updates the last location obtained. The first is optional, only if your application requires it.

Request get Location

[locationManager LocationQuery];

Updates Location

locationManager.locationUpdatedBlock = ^(CLLocation *location){
  NSLog(@"%@", location);
};

End updates Location

locationManager.locationEndBlock = ^(CLLocation *location){
  NSLog(@"%@", location);
};

Failed to obtain the Location

locationManager.locationErrorBlock = ^(NSError *error){
  NSLog(@"%@", error);
};

###Geocoding

Request Geocoding of User Location

[locationManager GeocodingQuery];

Get Address of User

Can multiple placemarks are received, so an array is returned

locationManager.geocodingBlock = ^(NSArray *placemarks){
    
    CLPlacemark *placemark = (CLPlacemark *)placemarks[0];
    
    NSLog(@"%@",[NSString stringWithFormat:@"%@ %@\n%@ %@\n%@\n%@",
       placemark.subThoroughfare ? placemark.subThoroughfare : @"",
       placemark.thoroughfare ? placemark.thoroughfare : @"",
       placemark.postalCode ? placemark.postalCode : @"",
       placemark.locality ? placemark.locality : @"",
       placemark.administrativeArea ? placemark.administrativeArea : @"",
       placemark.country ? placemark.country : @""]);
};

Failed to obtain Address

locationManager.geocodingErrorBlock = ^(NSError *error){
  NSLog(@"%@", error);
};

Reverse Geocoding

Request Reverse Geocoding

[locationManager ReverseGeocodingQueryWithText:@"1755 Embarcadero Road Palo Alto, CA 94303"];

Response

Can multiple placemarks are received, so an array is returned

locationManager.reverseGeocodingBlock = ^(NSArray *placemarks){
  for (int i = 0; i < [placemarks count]; i++){
     CLPlacemark * thisPlacemark = [placemarks objectAtIndex:i];
     NSLog(@"%@", thisPlacemark);
  }
};

Failed block

locationManager.reverseGeocodingErrorBlock = ^(NSError *error){
  NSLog("%@", error);
};

Get last stored location

You can also get the latest location of the user stored persistently for those cases in which the location is not available.

NSLog(@"%@",locationManager.getLastSavedLocation);

Get the route between two points.

You can try changing the parameters in the sample project, changing the parameters of latitude and longitude. The means of transport can also be chosen, walking or automovile, for default it's automovile.

        if(!error){
           
            [routes enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
                
                MKRoute *route = obj;
                
                MKPolyline *line = [route polyline];
                
                [self.mapView addOverlay:line];
                
                NSLog(@"Rout Name : %@",route.name);
                
                NSLog(@"Total Distance (in Meters) :%f",route.distance);
                
                NSArray *steps = [route steps];
                
                NSLog(@"Total Steps : %lu",(unsigned long)[steps count]);
                
                [steps enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
                    
                    NSLog(@"Rout Instruction : %@",[obj instructions]);
                    
                    NSLog(@"Rout Distance : %f",[obj distance]);
                    
                }];
            }];
        }else{
            NSLog(@"%@", [error localizedDescription]);
        }

    }];
