iOS Placemark property and reverse geocoding

[Fuzzball27]

I understand that reverse geocoding takes a while to return values, but I do not understand how to get the values it returns at the proper time. I have a CLPlacemark property in the class that uses the geocoder, and in the geocoder completion manager I have the following line of code:

placemark = [placemarks objectAtIndex:0];

(I have verified that the values are indeed being passed from placemarks to placemark by using NSLog(@"%@", placemark.x) at the end of the completion handler.)

The problem that I am having is this: I am using placemark.locality and placemark.administrativeArea as part of an NSString property in a method that is called after the method with the reverse geocoding. Either the property placemark is loosing it's values (which I don't believe is the case), or the method after the geocoding method is finished executing before the reverse geocoding is finished.

What I need to know is how can I ensure that the NSString property isn't given null values by the placemark property, and that the locality and administrative area are given instead?

The issue was indeed timing. I resolved it by moving CLGeocoder to the superclass of the class I was originally using, and having the completion handler give the original class the location info.
