MKMapView - Convert users co-ordinate to a string?

I'd like to grab the users location as a co-ordinate and convert it to a string -- any ideas? I've searched and can't find any solu开发者_C百科tion.

Thank you,

do you mean string as in NSString *latAsString = [NSString stringWithFormat:@"%f",newLocation.latitude];

or do you mean convert the lat/long into a street address? (reverse geocode)
