Cells are empty in table view

Question

Hello,

I am trying to design a news feed/RSS Reader with a table view. I wrote the code and ran it on my iOS device. Unfortunately the news feed will not appear. It is just an empty tableview. & yes, I connected everything in the storyboard.

HEADER FILE

import UIKit/UIKit.h

 @interface TableViewController : UITableViewController <NSXMLParserDelegate>

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


 @end

IMPLEMENTATION FILE

import "TableViewController.h"

@interface TableViewController () {

    NSXMLParser *parser;
    NSMutableArray *feeds;
    NSMutableDictionary *item;
    NSMutableString *title;
    NSMutableString *link;
    NSString *element;
}

@end

@implementation TableViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    feeds = [[NSMutableArray alloc] init];
    NSURL *url = [NSURL URLWithString:@"http://rss.cnn.com/rss/cnn_topstories.rss"];
    parser = [[NSXMLParser alloc] initWithContentsOfURL:url];
    [parser setDelegate:self];
    [parser setShouldResolveExternalEntities:NO];
    [parser parse];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return feeds.count;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
    cell.textLabel.text = [[feeds objectAtIndex:indexPath.row] objectForKey:@"title"];

    return cell;
}

-(void)parser:(NSXMLParser *)parser didStartElement:(nonnull NSString *)elementName namespaceURI:(nullable NSString *)namespaceURI qualifiedName:(nullable NSString *)qName attributes:(nonnull NSDictionary<NSString *,NSString *> *)attributeDict {

    element = elementName;

    if ([element isEqualToString:@"item"]) {
        item = [[NSMutableDictionary alloc] init];
        title = [[NSMutableString alloc] init];
        link = [[NSMutableDictionary alloc] init];
    }

}


-(void)parser:(NSXMLParser *)parser didEndElement:(nonnull NSString *)elementName namespaceURI:(nullable NSString *)namespaceURI qualifiedName:(nullable NSString *)qName {

    if ([elementName isEqualToString:@"item"]) {
        [item setObject:title forKey:@"title"];
        [item setObject:link forKey:@"link"];

        [feeds addObject:[item copy]];

    }
}


-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {

    if ([element isEqualToString:@"title"]) {
        [title appendString:string];

    }   else if ([element isEqualToString:@"link"]) {

        [link appendString:string];
    }
}

-(void)parserDidEndDocument:(NSXMLParser *)parser {

    [self.tableView reloadData];
}


@end
