    <p>Alright. I'm having trouble passing data through a segue from one UITableViewController to another. The proper information does not load. Without a bunch of endless talk about the setup, here goes:</p> <p>On the upper (passing) viewController side:</p> <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([segue.identifier isEqualToString:@"deriv"]) { NSIndexPath *indexPath = [self.tableView2 indexPathForSelectedRow]; DerivationController *destViewController = segue.destinationViewController; destViewController.derivationName = [equationsList2 objectAtIndex:indexPath.row]; } </code></pre> <p>On the receiving viewController side:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *simpleTableIdentifier = @"derivCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier]; } cell.textLabel.text = [derivations objectAtIndex:indexPath.row]; cell.detailTextLabel.text = [details objectAtIndex:indexPath.row]; return cell; } </code></pre> <ul> <li><p>equationsList2 is a list of equations in an NSArray instance. Depending on which one is selected, cell.textLabel and cell.detailTextLabel are set accordingly from NSArrays "derivations" and "details".</p></li> <li><p>The declaration for DerivationController.h is on the passing viewController's header list.</p></li> <li><p>No errors are thrown.</p></li> </ul> <p>Any ideas?</p> <p>Code for setting 'derivations' and 'detail':</p> <pre><code>if ([_derivationName isEqualToString:@"Momentum-Velocity"]) { // Equation 1: derivations = [NSArray arrayWithObjects: @"Momentum", @"Mass", @"Velocity", nil]; details = [NSArray arrayWithObjects: @"Momentum units in kg ∙ m/s", @"Mass units in kilograms (kg)", @"Velocity units in meters/second (m/s)", nil]; </code></pre>

    1. COCould you post the code for `setDerivationName` in your receiver view controller? And also the code where you set the properties `derivations` and `details` in the receiver VC.

    3. COYou haven't stated the problem yet. Your `prepareForSegue` method appears to be passing a string value to a `derivationName` property. Is that string not getting passed?

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.
