I have two sets of geo-coordinates and I am trying to calculate the distance between them. I have done some digging around, but cannot figure out how to do it. I am trying to get the distance in miles between the user(userLatitude/userLongitude) and the place (placeLatitude/placeLongitude). My coordinates are stored as NSStrings as displayed below. Does anyone know how to do this? Thank you all!
NSString *userLatitude =[(PDCAppDelegate *)[UIApplication sharedApplication].delegate
getUserLatitude];
NSString *userLongitude =[(PDCAppDelegate *)[UIApplication sharedApplication].delegate
getUserLongitude];
NSString *placeLatitude = [element1 objectForKey:@"placeLatitude"];
NSString *placeLongitude = [element1 objectForKey:@"placeLongitude"];
This might help you. Try to create CLLocation from lat long you have
CLLocation* Location1;
CLLocation* Location2;
CLLocationDistance distance = [Location1 distanceFromLocation:Location2];
From the following you can get the distance.
CLLocation *locA = [[CLLocation alloc] initWithLatitude:currentLocation.latitude longitude:currentLocation.longitude];
CLLocation *locB = [[CLLocation alloc] initWithLatitude:[[element1 objectForKey:@"placeLatitude"] doubleValue] longitude:[[element1 objectForKey:@"placeLongitude"] doubleValue]];
CLLocationDistance currentDistance = [locA distanceFromLocation:locB];
