Answer 1

使用CLLocationManagerDelegate方法

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

[map setShowsUserLocation:TRUE];

map是MKMapView的对象。

Answer 3

使用此委托方法

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

        if (userLocation_) {
            [userLocation_ release];
        }
        userLocation_ = [newLocation retain];
    }
