I've got myself some of a newbie problem.
I got this method to determine the zip code where the iPhone is located, based on GPS coordinates. Reverse Geocoding. My method works, I know this, since it has no problem writing out the correct zip code to a label.
But I need this zip code to be stored in a string that I can use inside a method I use to compose a SMS.
Anyone can help me with that?
Tell me if an source code is necessary! (Just not currently sitting on my work comp)
Clearly i've been misunderstood, should have posted som code.
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
NSLog(#"didUpdateToLocation: %#", newLocation);
CLLocation *currentLocation = newLocation;
// Reverse Geocoding
NSLog(#"Resolving the Address");
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
NSLog(#"Found placemarks: %#, error: %#", placemarks, error);
if (error == nil && [placemarks count] > 0) {
placemark = [placemarks lastObject];
**postalCode** = [NSString stringWithFormat:#"%#",
placemark.postalCode];
} else {
NSLog(#"%#", error.debugDescription);
}
} ];
}
Here i try to save the zip code inside the NSString named postalCode (highlighted with "**")
I try to load it again in sms composer
-(void)displaySMSComposerSheet
{
CLLocation *currentLocation;
// Reverse Geocoding
NSLog(#"Resolving the Address");
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
NSLog(#"Found placemarks: %#, error: %#", placemarks, error);
if (error == nil && [placemarks count] > 0) {
placemark = [placemarks lastObject];
postalCode = [NSString stringWithFormat:#"%#",
placemark.postalCode];
} else {
NSLog(#"%#", error.debugDescription);
}
} ];
MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.recipients = [NSArray arrayWithObjects:#"1220", nil];
picker.body = [NSString stringWithFormat:#"Dog %#", (placemark.)postalCode];
picker.messageComposeDelegate = self;
[self presentModalViewController:picker animated:YES];
}
only prints out in the SMS window:
Dog (null)
And i'm sure i have the coordinates, they get printed out in the output.
Hope this helps to understand the question better
