    <p>I have a problem of storing data on table view.</p> <p>It's a menu app that has a button which will pop over a table view and display them all the dishes they've ordered, I'm using the NSMutableArray to store the data, however whenever I close the table view, the data in the table will be reset to the initial status, which is the empty table.</p> <p>What should I do to solve this issue, thanks for any help!</p> <p>I'm using the FPPopover library to show the pop over table view, here's the code:</p> <pre><code>- (IBAction)revealOrderList:(id)sender { SAFE_ARC_RELEASE(popover); popover=nil; OrderListViewController *controller = [[OrderListViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:controller]; SAFE_ARC_RELEASE(controller); controller=nil; popover = [[FPPopoverController alloc] initWithViewController:nc]; popover.tint = FPPopoverDefaultTint; popover.contentSize = CGSizeMake(300, 500); [popover presentPopoverFromView:sender]; } </code></pre> <p>And in the pop over table view:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.leftBarButtonItem = self.editButtonItem; orderList = [[NSMutableArray alloc] initWithObjects:@"One", @"Two", @"Three", nil]; //add the add button UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject)]; self.navigationItem.rightBarButtonItem = addButton; } - (void)insertNewObject { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Add new thing" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil]; //Set the style of UIAlertView alert.alertViewStyle = UIAlertViewStylePlainTextInput; //Show the UIAlertView [alert show]; } </code></pre>

    1. COAdd some code? If you unload the view controller the data is going with it.

    2. COYour primary problem is that you are relying on either the view or the controller to persist the model.

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.
