Is CLGeocoder supported on iOS 4.2? - ios

Question

When I look at apple docs, I get a bit confused.
On one hand they have statements indicating that CLGeocoder can be used from iOS 5 onwards.
On the other hand they have statements like: "For applications running on iOS 4.1 and earlier, you must perform reverse-geocoding requests using the MKReverseGeocoder class"
Then what about the 4.2 onwards range? Can it support CLGeocoder or not?
Does anyone have an answer via their first hand experience with an iPhone with 4.1 < version < 5.0 installed where they figured out if CLGeocoder will work or not?

Answer 1

Currently I call
[[CLGeocoder class] instancesRespondToSelector:#selector(reverseGeocodeLocation:completionHandler:)]
This always returns false on devices below 5.0
I'm still trying to figure out why as the documentation states its supported 4.1 onwards.

Answer 2

Here is quote from the Location Awareness Programming Guide:
In iOS, you can use either the CLGeocoder or MKReverseGeocoder class
to handle reverse-geocoding requests. The CLGeocoder is the preferred
class to use and is available in iOS 5.0 and later. However, if your
application must run on earlier versions of iOS, you can use the
MKReverseGeocoder class.
MKReveresGeocoder is still there in 5.0, but is deprecated. That is, you could still use it to simplify support for multiple iOS versions in your code.

- (IBAction)geoCodeLocation:(id)sender{
[self.geoCoder reverseGeocodeLocation: locationManager.location completionHandler:
^(NSArray *placemarks, NSError *error) {
CLPlacemark *placemark = [placemarks objectAtIndex:0];
NSLog(#"placemark %#",placemark);
//String to hold address
NSString *locatedAt = [[placemark.addressDictionary valueForKey:#"FormattedAddressLines"] componentsJoinedByString:#", "];
NSLog(#"addressDictionary %#", placemark.addressDictionary);
NSLog(#"placemark %#",placemark.region);
NSLog(#"placemark %#",placemark.country); // Give Country Name
NSLog(#"placemark %#",placemark.locality); // Extract the city name
NSLog(#"location %#",placemark.name);
NSLog(#"location %#",placemark.ocean);
NSLog(#"location %#",placemark.postalCode);
NSLog(#"location %#",placemark.subLocality);
NSLog(#"location %#",placemark.location);
//Print the location to console
NSLog(#"I am currently at %#",locatedAt);
//Set the label text to current location
[locationLabel setText:locatedAt];
}];
