    <p>I created an IBAction that I link to saveButton, when I call all core data methods inside the IBAction it works fine in following code:</p> <pre><code>- (IBAction)saveButtonTap:(id)sender{ NSManagedObjectContext *context = [self managedObjectContext]; NSManagedObject *object = [NSEntityDescription insertNewObjectFor:@"Person" inManagedContext:context]; [self setValue:firstNameTextField.text forKey:@"firstName"]; [self setValue:lastNameTextField.text forKey:@"lastName"]; NSError *error = nil; if (![context save:&amp;error]) NSLog(@"Can't save transaction - %@ || %@ ", error, [error localizedDescription]); } </code></pre> <p>And when I separate the core data saving methods as the below, the saved firstName and lastName, showing null when fetched. It didn't return error, but I have no idea after googling all day. Could someone point anything wrong with my code?</p> <p><strong>Person.h + Person.m</strong></p> <pre><code>@interface Person : NSManagedObject @property(strong) NSString *firstName; @property(strong) NSString *lastName; - (void)save; @end @implementation Person @synthesize firstName; @synthesize lastName; - (void)save{ [self setValue:self.firstName forKey:@"firstName"]; [self setValue:self.lastName forKey:@"lastName"]; } @end </code></pre> <p><strong>mainViewController.h + mainViewController.m</strong></p> <pre><code>@interface mainViewController : UIViewController @property(strong) ManagedObjectContext *context; @property(strong) Person *person; - (IBAction)saveButtonTap:(id)sender; @end @implementation mainViewController @synthesize context; @synthesize person; - (void)viewDidLoad{ // ... some view did Load rituals if(context == nil){ context = [self managedObjectContext]; // Assume this method calls for managed object context from shared application. } if(person == nil){ person = [NSEntityDescription insertNewObjectFor:@"Person" inManagedContext:context]; } } - (IBAction)saveButtonTap:(id)sender{ person.firstName = firstNameTextField.text; person.lastName = lastNameTextField.text; [self.person save]; NSError *error = nil; if (![context save:&amp;error]) NSLog(@"Can't save transaction - %@ || %@ ", error, [error localizedDescription]); } @end </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.
