iOS6 CLPlacemark to show street name

I want to show the full street name of the user location, with the below code I can only show the city name :

 -(void) reverseGeocode:(CLLocation *)location{
   CLGeocoder *geocoder = [[CLGeocoder alloc]init];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {    
    if(error) {
        NSLog(@"Error");
        return;
    }  
    if(placemarks) {
        CLPlacemark *placemark = placemarks [0];
        NSArray *lines = placemark.addressDictionary[ @"FormattedAddressLines"];
        NSString *addressString = [lines componentsJoinedByString:@"\n"];
        NSLog(@"Address: %@", addressString);
    }
}];}

Any ideas on how I can get the street name ?

According to the documentation: https://developer.apple.com/library/ios/documentation/CoreLocation/Reference/CLPlacemark_class/Reference/Reference.html

Under "Accessing the Placemark Attributes" There is a property called "thoroughfare".

Check it out :)

Thank you for your answer ! Now, I used this code, but I am getting (null) any ideas about what's wrong ?

CLGeocoder *geocoder = [[CLGeocoder alloc]init];
   [geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
   if(error) {
        NSLog(@"Error");
        return;
    }
   if(placemarks) {
    CLPlacemark *placemark = [placemarks lastObject];
    NSLog(@"%@", placemark.thoroughfare); }
    }];

Try:

if(placemarks) {
    CLPlacemark *placemark = [placemarks objectAtIndex:0];
    NSLog(@"%@", placemark.thoroughfare); }

or:

if(!error) {
         CLPlacemark *placemark = [placemarks objectAtIndex:0];
         NSLog(@"%@", placemark.thoroughfare); }
    }else {
       //error
    }];

Same issue, I don't know how to get rid form it :s Knowing that if I do :

    NSLog(@"%@", placemark);

I get the full address with the coordinates....

Aaah. I think I know what the problem is (if my last bit of code doesn't work) - If you log out you 'location'-property, that will be nil. And the address of nil, is nil.

instead of adding location as a parameter, try this:

CLGeocoder *geocoder = [[CLGeocoder alloc]init];
   [geocoder reverseGeocodeLocation:self.mapView.userLocation.location completionHandler:^(NSArray *placemarks, NSError *error) {
   if(error) {
        NSLog(@"Error");
        return;
    }
   if(placemarks) {
    CLPlacemark *placemark = [placemarks lastObject];
    NSLog(@"%@", placemark.thoroughfare); }
    }];

You'd have to add this in you H file:

@property (strong, nonatomic) MKMapView *mapView;

and import the mapkit framework if you haven't already: #import <MapKit/MapKit.h>

EDIT If you're just using the coreLocation framework -never mind this code, you shouldn't have to use mapview to get it to work

Now, it is giving to me : Error

Probably because mapview and it's delegates is not implemented. But never mind that code. Just using CLLocation should work perfectly - I'll make a tiny example later, but now it's breakfast :)

Interesting! I made a test project. At first I received the same error as you (null). THEN, I switched from IOS simulator to a real iPhone - and suddenly it worked! I don't know why this is - but the problem obviously has something to do with the simulator (at least in my case)

Thank you for the efforts, but unfortunately I am still getting (null) :s By the way I am running on iOS6, will this be a problem ?

I don't see why it would. There is nothing in Apple's documentation to back that up. Considering it only worked on my iphone which is running IOS7, it's a little bit hard to test with IOS6
