CLLocationManager didUpdateLocations or didUpdateToLocation

Question

I my iOS i am using CLLocationManager, but i am not sure which delegate method to use to get the location updates. There are two methods

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

and

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

I know that i should be using the second one because the first one is deprecated but then i have set the deployment target for my app to be 6.0. So which one i should use? In the image attached , just beside this method

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

it says 6.0. So what does it mean its deprecated in iOS 6.0 or its available till 6.0. My guess is that, i should be using

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

and it should be fine. Any suggestions?

Any specific reason why you're still supporting iOS 6.x? – n00bProgrammer Jul 27 '15 at 07:16 — n00bProgrammer, Jul 27 '15 at 07:16

I am also faced the same issue in my old project, So I tried the following method, then working fine for me

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

The delegate above is deprecated in iOS 6. Now the following should be used:

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

In order to get the last position, simply get the last object of the array:

[locations lastObject]

In other words, [locations lastObject] (new delegate) equals newLocation (old delegate)

example

iOS6 and above

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
CLLocation *newLocation = [locations lastObject];
CLLocation *oldLocation;
if (locations.count >= 2) {
    oldLocation = [locations objectAtIndex:locations.count-1];
} else {
    oldLocation = nil;
}
NSLog(@"didUpdateToLocation %@ from %@", newLocation, oldLocation);

}

if you use in iOS6 and below add the following method also

 - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
[self locationManager:locationManager didUpdateLocations:[[NSArray alloc] initWithObjects:newLocation, nil]];
}
