Question

first of all here is my code:

@protocol SearchTableViewControllerDelegate

@required
- (void)didSelectFileCardsContent:(FileCardsContent*)content;

@end


@interface SearchTableViewController : UITableViewController <UISearchBarDelegate, UISearchDisplayDelegate>{

    id <SearchTableViewControllerDelegate> delegate;
...
}

@property (nonatomic, assign) id <SearchTableViewControllerDelegate> delegate;
...
@end
---------------------------------------------------

@implementation SearchTableViewController

@synthesize ... delegate;
...
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    FileCardsContent *fileCardToShow = [self.tableData objectAtIndex:indexPath.row];
    [self.delegate didSelectFileCardsContent:fileCardToShow];

}
...
@end
---------------------------------------------------

@interface FileCardsViewCotroller : UIViewController <SearchTableViewControllerDelegate>{
...
@end
---------------------------------------------------

@implementation FileCardsViewCotroller
...
- (void)didSelectFileCardsContent:(FileCardsContent*)content{
    [managedFileCards insertSingleContent:content];
    self.currentFileCardsContent = content;
    questionView1.text = currentFileCardsContent.question;

}
@end

My problem is – (void)didSelectFileCardsContent:(FileCardsContent*)content in FileCardsViewCotroller is never called.
There are no compiler warnings or errors. I`m not familiar with protocols and delegates so is suggest there is a conceptually problem.
Anny ideas?

You just aren’t assigning your delegate to anything so the message is sent to nil.
