Can I customize the title of the buttons at the Camera Controls with Custom Camera Overlay?

Question

I have a big issue, I'm developing an Application that is in Spanish, so al the labels and controls needs to be in Spanish. The thing is when I pick a Photo from the Camera, the Default Camera Controls comes in english: "Take Photo", "Cancel" and "Retake". My question is if I can customize this buttons to make it appear in Spanish: "Tomar Foto", "Cancelar" y "Volver a tomar".

This is actually my code:

-(IBAction)takePhoto :(id)sender
{
    if (fotos.count <= 3) {
        UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
        {
            [imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
        }
        imagePickerController.showsCameraControls = YES;

        // image picker needs a delegate,
        [imagePickerController setDelegate:(id)self];

        // Place image picker on the screen
        if([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0)
        {
            [[NSOperationQueue mainQueue] addOperationWithBlock:^{

                [self presentViewController:imagePickerController animated:NO completion:nil];
            }];
        }
        else
        {
            [self presentViewController:imagePickerController animated:NO completion:nil];
        }
    }
}

[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"de", @"en", @"fr", nil] forKey:@"AppleLanguages"];

[[NSUserDefaults standardUserDefaults] synchronize]; //to make the change immediate
