    <p>I've created a data class name Person with an integer and a bool instance variables. Inside my ViewController "initWithNibName" I initialize </p> <pre><code> anObject = [[Person alloc] init]; </code></pre> <p>Inside the View controller have defined an IBAction. I want to toggle the bool value in person class on each click. I can display text on each click and even append it. But unable to print the int value or bool value from my Data Class.</p> <p>Person.h file</p> <pre><code> @interface Person : NSObject { int pheight; BOOL palive; } -(Person*) init; -(void) setPersonheight: (int) h andAlive: (BOOL) pn; -(int) personHeight; -(void) display; -(BOOL) isPersonAlive; @end </code></pre> <p>Person.m file</p> <pre><code> #import "Person.h" @implementation Person -(Person*) init{ self = [super init]; if (self){ [self setPersonheight:5 andAlive:YES]; } return self; } -(void) setPersonheight: (int) h andAlive: (BOOL) pn{ pheight = h; palive = pn; } -(int) personHeight{ return pheight; } -(void) display{ if(palive){ palive = NO; } else { palive = YES; } } -(BOOL) isPersonAlive{ return YES; } @end </code></pre> <p>*ViewController.h file</p> <pre><code> @interface Demo9ViewController : UIViewController { UILabel *outlet; Person *anObject; //id anObject; } @property (nonatomic, retain) IBOutlet UILabel *outlet; -(IBAction) displayPerson:(id) sender; @end </code></pre> <p>*View controller.m file</p> <pre><code> -(IBAction) displayPerson:(id) sender{ [anObject display]; NSString *myPerson = [NSString stringWithFormat:@"%d",[anObject personHeight]]; NSString *string = [outlet.text stringByAppendingString:myPerson]; outlet.text = string; } </code></pre> <p>Can someone tell, what wrong am I doing here ?</p> <p>Thanks,</p> <p>Regards, M Tahir</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
