    <p>(storyboard image) <a href="http://i.stack.imgur.com/DUZ12.png" rel="nofollow">http://i.stack.imgur.com/DUZ12.png</a></p> <p>Have 3 text fields where user inputs data and saves it. Upon opening the application, if there is any save data, the previous input is displayed within the text fields. Problem is, there is only one set of data, while it needs to be an array with multiple people's information. I would like to instead create a navigation controller with cells with names and upon clicking on them it displays the correlating contact info.</p> <p>viewcontroller.h</p> <pre><code> @interface ArchiveViewController : UIViewController @property (strong, nonatomic) IBOutlet UITextField *name; @property (strong, nonatomic) IBOutlet UITextField *address; @property (strong, nonatomic) IBOutlet UITextField *phone; @property (strong, nonatomic) NSString *dataFilePath; - (IBAction)saveData:(id)sender; @end </code></pre> <p>viewcontroller.m</p> <pre><code>@interface ArchiveViewController () @end @implementation ArchiveViewController - (void)viewDidLoad { [super viewDidLoad]; NSFileManager *filemgr; NSString *docsDir; NSArray *dirPaths; filemgr = [NSFileManager defaultManager]; // Get the documents directory dirPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES); docsDir = dirPaths[0]; // Build the path to the data file _dataFilePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent: @"data.archive"]]; // Check if the file already exists if ([filemgr fileExistsAtPath: _dataFilePath]) { NSMutableArray *dataArray; dataArray = [NSKeyedUnarchiver unarchiveObjectWithFile: _dataFilePath]; _name.text = dataArray[0]; _address.text = dataArray[1]; _phone.text = dataArray[2]; } } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (IBAction)saveData:(id)sender { NSMutableArray *contactArray; contactArray = [[NSMutableArray alloc] init]; [contactArray addObject:self.name.text]; [contactArray addObject:self.address.text]; [contactArray addObject:self.phone.text]; [NSKeyedArchiver archiveRootObject: contactArray toFile:_dataFilePath]; } @end </code></pre> <p>Thank you for your time.</p>

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.
