mkreversegeocoder

I keep getting this randomly when I run my gps app I'm building. It doesn't happen everytime, and the coordinates passed in are always valid (i nslog them). Is there documentation for these somewhere? EDIT: CLLocationCoordinate2D coord = CLLocationCoordinate2DMake(locManager.location.coordinate.latitude, locManager.location.coordinate.longitude); geocoder1 = [[MKReverseGeocoder alloc] initWithCoordinate:coord]; geocoder1.delegate = self; [geocoder1 start]; and then about half the time it returns an error. I tried releasing and re-assigning the geocoder if there was an error, but that didn't

I have an application that needs to have a similar search feature like the Apple "Maps" application (included with iPhone, iPod Touch and iPad). The feature in question should not be a hard thing to do, but I'm really clueless about how to input a Street Address in the search bar, and then obtaining coordinates for that address or something that can help me to actually move the map and center in that place. I mean, what do I have to query, does Apple provide an "address searching API method" ? or I need to use the google maps API directly ? I would love to hear how should it be done.
