Answer 1

You can set up monitoring location stuff in you VC as below

in viewDidLoad method do as below

CLLocationManager locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;(Accuracy according to your need)
[locationManager startUpdatingLocation];

than you have to overrite below two optional delegate methods of CLLocationManagerDelegate protocol

for iOS6+

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{}

and for iOS 2 to 6

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation

in these methods you will get updated location. use it as you want. every time location updated these method get calls.
