    <p>I am trying to edit the segue's target's data through <code>prepareForSegue</code>, but everything I try keeps returning the "unrecognized selector sent to instance ..." error. Is there a special way to edit my target's data, is it being deleted before I edit it or something like that? I just started picking this stuff up so I still don't have my head all the way around it. Here is a sample of some of my code</p> <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if([segue.identifier isEqualToString:@"managerSegue"]){ ASExpenseList *target = [segue destinationViewController]; NSIndexPath *row = [self.tableView indexPathForSelectedRow]; self.cellPressed = row.row; switch(self.cellPressed){ case 0: [target initWithData:self.oneTimeExpenses]; //PROBLEM LINE // target.expenses = [[NSMutableArray alloc] initWithArray:self.oneTimeExpenses]; ALSO PROBLEM target.title = @"One-Time"; //not breaking the program but not working </code></pre> <p>The <code>ASExpenseList</code> function I'm calling is really simple:</p> <pre><code>-(void) initWithData:(NSMutableArray *)newExpenses { self.expenses = newExpenses; [self.tableView reloadData]; } </code></pre> <p>So I am trying to set the target's data to some data I already have, and I am trying to dynamically change the title. The title change isn't working and the data lines are throwing errors. I'm guessing that I just misunderstand how it works, so any help or clarification would be awesome. Thanks!</p>

    2. COIt's not a good practice to start a method name with init, if it's not actually an init method (i.e. one that has id as the return type and returns self).

    3. CO@dasdom That doesn't make any sense. `title` is a property of the target view controller, not one of its views. Storyboards work perfectly well, though understanding how to use them correctly can take some time, especially for developers who are relatively inexperienced with Interface Builder.

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).
