UISearchDisplayController - results exists but are not displayed - ios

Question

I have strange problem with UISearchDisplayController.
My code is following:
numberOfRowsInSection:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if ([[self searchDisplayController] isActive])
{
return [self.itemsFound count];
} else {
return [self.items count];
}
return [self.items count];
}
cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
FavouriteTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[FavouriteTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Facilities *f = nil;
if ([[self searchDisplayController] isActive])
{
f = [self.itemsFound objectAtIndex:indexPath.row];
} else {
f = [self.items objectAtIndex:indexPath.row];
}
[cell.favouriteButton addTarget:self action:#selector(toggleFavourite:) forControlEvents:UIControlEventTouchUpInside];
[cell.titleLabel setText:f.name];
return cell;
}
next:
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:#"name contains[c] %#",searchText];
self.itemsFound = [self.items filteredArrayUsingPredicate:resultPredicate];
}
shouldReloadTableForSearchString:
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
self.itemsFound = nil;
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex: [self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
My table:
If I type letters, which are on the list:
Results exist but are not showing on a list.
On next picture there are no results and the screen shows correct info.
I have no idea why I can not show results on second screen while results are (displayed on console).
Do you have any idea ?
Thanks for your time.
