    <p>How can I do this?</p> <p>I have <strong>ViewController 1</strong>, and <strong>ViewController 2</strong>.</p> <p><strong>ViewController 1</strong> defines a protocol and <strong>ViewController 2</strong> conforms to it.</p> <p>I set <strong>ViewController 2</strong> has a delegate and invoke a method in <strong>ViewController 1</strong>. This method runs fine. And send confirmation back to my <strong>ViewController 2</strong>.</p> <p>I can exchange data between them, but I'm trying to figure out a way, to get data from a <strong>particular instance</strong> of <strong>ViewController 1</strong>, to <strong>ViewController 2</strong>.</p> <p>Because when I'm using my delegate, to run a method in <strong>ViewController 1</strong> it's not going for that particular instance that I'm interested in.</p> <p>Is there a way I can resolve this?</p> <p>Can I set my delegate, a delegate of a particular instance so I can get it's state? Is this possible? And if so, how?</p> <p>In other words, can I target a specific instance with my delegate?</p> <p>--</p> <p>p.s. if I try to get data of a property ruled by ViewController 1, it come has nil (I think this is because I'm not targeting a particular instance)! One way I can resolve it, is have a method that reads "already saved data". But I would be replicating code, and instantiating new objects with data that is already available in previous ViewControllers.</p> <p>Any help is most appreciated. Thank you in advance!</p> <p>Nuno</p> <p>edit:</p> <pre><code>SetupTableViewController *delegate = [[SetupTableViewController alloc] init]; [delegate setDelegate:self]; </code></pre> <p>Every property I try to get from this point on forward, is nil. How can I target this to a particular instance of my previous ViewController? I do not want to instantiate a new SetupViewController. What I really need is to access an existing instance of my SetupViewController.</p>

    1. COI think you need to show your code. Why do you have more than one instance of your view controller?

    2. COOkay, that is definitely your problem. You are creating a new instance and then assigning the new instance as the delegate. How do you create the second view controller? Is it pushed on? Segued on modally? etc?

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.
