    <p>Assuming that you DO want to set the other data source with only this row, you need to pass it as an array.</p> <pre><code>view.anotherviewArray= [NSArray arrayWithObject:[self.arrayFromAFNetworking objectAtIndex:indexPath.row]]; </code></pre> <p>But it's hard to tell from the little code that you have provided. I assume that since you are instantiating the viewController you are also transitioning to it below the provided code. If you are trying to set the array for a viewController already presented, you need to access that one, not create another, perhaps by having saved a reference to it an ivar within the current viewController or another accessible class. </p> <p>I would also not name a ViewController <code>view</code>, it is confusing to anyone reading the code later on. </p> <p>Editing for my comment below about traversing the hierarchy. Here is some code that I used in one iPad project to return the final presented viewController. This method is in the appDelegate. It is somewhat specific to my project, where there is only one navigationController. But you can adapt it to yours. You would test for a viewController that is of the class of your target view controller. </p> <pre><code>- (UIViewController *)topViewController { UIViewController *rootViewController = self.window.rootViewController; UIViewController *topViewController = rootViewController.presentedViewController; while (topViewController &amp;&amp; topViewController.presentedViewController) { topViewController = topViewController.presentedViewController; if ([topViewController isKindOfClass:[UINavigationController class]]) { UIViewController *presentedViewController = [(UINavigationController *) topViewController topViewController]; if (presentedViewController) { topViewController = presentedViewController; } } } return topViewController; } </code></pre> <p>The other approach is to set a property to it when it is created and presented. We don't have enough code to get a good idea of your app as a whole. Where are you creating the ViewController instance that you are displaying? By that I mean where you are calling a segue to it, or pushing it onto a navigationController or call presentViewController. Wherever that is, you need to set a property or ivar to it. Let's say that you use a property in your appDelegate as a very generic case. </p> <p>In your MyAppDelegate.h file you have</p> <pre><code>@property(nonatomic,strong) ViewController *viewController; </code></pre> <p>Wherever you first create it you set that property </p> <pre><code>MyAppDelegate *appDelegate = (MyAppDelegate*)[[UIApplication sharedApplication] delegate]; appDelegate.viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController"]; </code></pre> <p>I now think you are trying to add this to a mutableArray in the other ViewController. Then replacing your code from the tableViewCell above you would use MyAppDelegate <em>appDelegate = (MyAppDelegate</em>)[[UIApplication sharedApplication] delegate]; [appDelegate.viewController.mutableDataArray addObject:self.arrayFromAFNetworking objectAtIndex:indexPath.row]; [appDelegate.viewController.tableView reloadData];</p> <p>I will say that it is not great practice to use the appDelegate for the property. But it is a generic answer that would work. It's best to put it in a class which is common to the viewControllers that you are passing data between. Perhaps a single parent which holds these two viewControllers? </p>

    1. COI have not used viewController in actual project. It's only for the example. Once i have saved the row in an Array, how should i populate it in another UIViewController with tableView?

    2. COAgain that depends on code not seen. instantiateViewController creates a new viewController each time. It does not return a reference to one already created or one that you will create by the same call later in your code. If you need one already created, you need to access one already created you need access to that one through a property set when you created it (easier), or by traversing viewControllers in the hierarchy (harder). If for a later one, then by setting that value in an array set when it is instantiated

    3. COI had made the mistake of thinking that `[storyboard instantiateViewControllerWithIdentifier:]` returned a reference to an existing viewController. So if that is your issue, then I hope this helps. If not, please edit your question and provide more info.

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.
