Question

I was wondering if it was possible to get the state abbreviations from CLPlacemark?

administrativeArea The sta

Answer 1

As of at least iOS 8, CLPlacemark's administrativeArea returns a two-letter abbreviation for US States.

You don't need to extend CLPlacemark with a category like the one in the accepted answer as long as you're targeting iOS 8 and newer (which you should be by now).

CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder geocodeAddressString:@"1 Infinite Loop, Cupertino, CA" completionHandler:^(NSArray *placemarks, NSError *error) {
    CLPlacemark *placemark = [placemarks firstObject];
    NSLog(@"State: %@", placemark.administrativeArea);
}];

Run this and you'll get:

State: CA
