    <p>I have been struggling with that for some time. I have a tab bar application. In <code>SecondView</code> I define number2 and save it to <code>NSUserDefaults</code> as I want it to be remembered by the program at the next time the app is open. In the <code>FirstView</code> I want to do some calculation (and display the answer) that include number2 saved earlier. I can't get it working. In the code, I left only things that are working so far. Any help will be greatly appreciated.</p> <p>FirstViewController.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "SecondViewController.h" @interface FirstViewController : UIViewController { IBOutlet UILabel *labelAnswer; } -(IBAction)buttonCalc; @property(nonatomic, retain) UILabel *labelAnswer; @end </code></pre> <p>FirstViewController.m</p> <pre><code>#import "FirstViewController.h" #import "SecondViewController.h" @interface FirstViewController () @end @implementation FirstViewController @synthesize labelAnswer; -(IBAction)buttonCalc { float number1 = 2; //what should I put here (or somewhere else) to get number2 saved in second view? float answer = number1;// + number2 labelAnswer.text = [[NSString alloc] initWithFormat:@"%f", answer]; } </code></pre> <p>SecondViewController.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface SecondViewController : UIViewController { IBOutlet UITextField *textNumber2; NSUserDefaults *defaults; } -(IBAction)buttonSave; @property(nonatomic, retain) UITextField *textNumber2; @end </code></pre> <p>SecondViewController.m</p> <pre><code>#import "SecondViewController.h" @interface SecondViewController () @end @implementation SecondViewController @synthesize textNumber2; -(IBAction)buttonSave { //saving my data NSString *saveNumber2 = textNumber2.text; defaults = [NSUserDefaults standardUserDefaults]; [defaults setObject:saveNumber2 forKey:@"savedNumber2"]; [defaults synchronize]; } - (void)viewDidLoad { [super viewDidLoad]; //loading my data defaults = [NSUserDefaults standardUserDefaults]; NSString *loadNumber2 = [defaults objectForKey:@"savedNumber2"]; [textNumber2 setText:loadNumber2]; } </code></pre>

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.
