    <p>i have to execute a high number of reverseGeocodeLocation request, i use this method for doing that:</p> <pre><code> for (Photo *photo in arrayWhitPicture) { CLGeocoder *geocoder = [[CLGeocoder alloc] init]; [queue addOperationWithBlock:^{ [geocoder reverseGeocodeLocation:[[CLLocation alloc] initWithLatitude:[photo.latitude doubleValue] longitude:[photo.longitude doubleValue]] completionHandler:^(NSArray *placemarks, NSError *error) { if (error){ NSLog(@"Geocode failed with error: %@", error); return; } CLPlacemark *myPlacemark = [placemarks objectAtIndex:0]; NSString *city = myPlacemark.locality; NSLog(@"My country code: %@", city); }]; }]; } </code></pre> <p>this code actual work, but the problem is that some of these request (like half) get this error:</p> <pre><code>Error Domain=kCLErrorDomain Code=2 </code></pre> <p>after a few research i think this happen because i do a lot of request in short amount of time in fact the apple documentations say:</p> <blockquote> <p>Send at most one geocoding request for any one user action.</p> <p>When you want to update the user’s current location automatically (such as when the user is moving), issue new geocoding requests only when the user has moved a significant distance and after a reasonable amount of time has passed. For example, in a typical situation, you should not send more than one geocoding request per minute.</p> </blockquote> <p>so my question is: my error is really caused by the fact that i do a lot of request, and in that case what can i do to resolve this problem, do you know other system apart to use the reverseGeocoding?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
