Using UISearchViewController without an underlying UITableView (from a storyboard)

Using UISearchViewController without an underlying UITableView (from a
storyboard)

I'm trying to use a UISearchDisplayController to search with CLGeocode as
the user types, for use with an MKMapView. My view controller has only two
things in it - the UISearchBar associated with the
UISearchDisplayController and the map view. I'm using a Storyboard.
Normally one would do this with an underlying table view and would declare
a prototype cell there, but there seems to be no way of doing that here
since I don't have the table view. So I created a subclass of
UITableViewCell called SearchTableViewCell, with associated nib.
The nib contains one label, with this outlet connected:
@interface SearchTableViewCell : UITableViewCell
@property (unsafe_unretained, nonatomic) IBOutlet UILabel *textLabel;
@end
I load the nib in viewDidLoad:
[self.searchDisplayController.searchResultsTableView registerNib:[UINib
nibWithNibName:@"SearchTableViewCell" bundle:[NSBundle mainBundle]]
forCellReuseIdentifier:@"CellIdentifier"];
I get the data from CLGeocoder like this:
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
shouldReloadTableForSearchString:(NSString *)searchString {
[self.geocoder geocodeAddressString:searchString
completionHandler:^(NSArray *placemarks, NSError *error) {
self.placemarks = placemarks;
[self.searchDisplayController.searchResultsTableView reloadData];
}];
return NO;
}
And my tableview code looks like this:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return [self.placemarks count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *kCellID = @"CellIdentifier";
SearchTableViewCell *cell = (SearchTableViewCell *)[tableView
dequeueReusableCellWithIdentifier:kCellID forIndexPath:indexPath];
CLPlacemark *placemark = self.placemarks[indexPath.row];
NSString *addressString =
CFBridgingRelease(CFBridgingRetain(ABCreateStringWithAddressDictionary(placemark.addressDictionary,
NO)));
cell.textLabel.text = addressString;
return cell;
}
The search part is working - when I get to cellForRowAtIndexPath there is
data in self.placemarks. However, the line that dequeues a new cell is
failing with an exception the first time it's called:
'NSUnknownKeyException', reason: '[<NSObject 0x1a840d40>
setValue:forUndefinedKey:]: this class is not key value coding-compliant
for the key textLabel.'
My cell object is compliant for textLabel, but I'm wondering about that
NSObject there in the error message - is the object being returned not a
SearchTableViewCell? It is configured in IB to use the correct class. And
why is the dequeue method checking for textLabel anyway? I'm pretty sure
I've had custom table cells before that had no textLabel field.
Any suggestions on where I've gone wrong?
