.h

@interface UfficiViewController : ViewController<UITableViewDelegate,UITableViewDataSource,UISearchDisplayDelegate,NSURLConnectionDelegate>
@property (weak,nonatomic) IBOutlet UITableView* tableViewUffici;
@end

.m

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {


    self.tableViewUffici.delegate = self;
    self.tableViewUffici.dataSource = self;
    //Ricarico la tableView perchè devo attendere i tempi della connessione
    [self.tableViewUffici reloadData];
}

Answer 1

In the storyboard, you have wired a table view to an outlet named tableView . Then in the view controller code you deleted it but you forgot to unwire it. Please note that this is not an error from the compiler. It's runtime error.

Solution

1. Go to the storyboard. Click on the view controller.
2. Open Connections Inspector (cmd + option + 6).
3. Look for a connection with name tableView .
4. Delete it.

Answer 2

change the

@property (weak,nonatomic) IBOutlet UITableView* tableViewUffici;

to

@property (nonatomic,strong) IBOutlet UITableView* tableViewUffici;

This may help you.
