iOS Не удалось отобразить NSMutableArray для TableView

Question

Ниже представлен мой файл .m. Я объявляю NSMutableArray в .h файле, но он все еще не может отобразить мой массив от xmlparser до UITableView. Прошу вас, руководствуясь приведенным ниже кодом. Скорее всего, это мои таблицы таблиц, поскольку я могу вывести данные из массива фида. Я также перезагружаю контроллер табличного представления.

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // output = [[NSMutableArray alloc]initWithObjects:@"red",@"green", nil]; 
    NSLog(@"Response recieved"); 
    output= [[NSMutableArray alloc] init]; 
    feeds = [[NSMutableArray alloc] init]; 
// NSString *severity = @"Informational"; 
    NSString *soapMessage = @"<?xml version=\"1.0\" encoding=\"utf-8\"?>" 
    "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">" 
          "<soap:Body>" 
          " <IncidentGetList xmlns=\"https://www.monitoredsecurity.com/\">"

          "</soap:Envelope>"; 


    NSURL *url = [NSURL URLWithString:@"https://api.monitoredsecurity.com/SWS/incidents.asmx"]; 
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];

Создание IBOutlet для UITableView и назвать его tableView или что-нибудь еще, а затем вызвать reloadData метод на него в вашем следующем методе:

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
    namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName 
{ 
    if ([elementName isEqualToString:@"SecurityIncidentSummary"]) { 

     [IncidentGetList setObject:Severity forKey:@"Severity"]; 

     [feeds addObject:[IncidentGetList copy]]; 
    } 
    [tableView reloadData]; 
}
