    <p>I am having trouble pushing from a tableview to a detail view. When I click the tableview cell, the cell highlights but does not push to the detail view. I am using this to transition to the detail view:</p> <pre><code>[self.navigationController pushViewController:detailViewController animated:YES]; </code></pre> <p>I have read that this is a common issue, but am somehow unable to figure out a solution. My full .m file is below. If anyone has any recommendations that would be amazing. Thank you!</p> <pre><code>#import "ViewController.h" #import "DetailViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.title = @"title"; [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; NSURL *url = [NSURL URLWithString:@"http://website.com/json.php"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [[NSURLConnection alloc] initWithRequest:request delegate:self]; // Do any additional setup after loading the view, typically from a nib. } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; news = [NSJSONSerialization JSONObjectWithData:data options:nil error:nil]; [mainTableView reloadData]; } - (int)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [news count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MainCell"]; if(cell == nil){ cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MainCell"]; } cell.textLabel.text = textForMyLabel; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle: @"Back" style: UIBarButtonItemStyleBordered target: nil action: nil]; [[self navigationItem] setBackBarButtonItem: newBackButton]; DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; detailViewController.title = [[news objectAtIndex:indexPath.row] objectForKey:@"name"]; detailViewController.newsArticle = [news objectAtIndex:indexPath.row]; [self.navigationController pushViewController:detailViewController animated:YES]; } </code></pre>

    3. COyou need to first have a navigation controller allocated with a rootviewcontroller. Then you can only push other views.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
