    <p>I have a variable, editForm, that is used as a pointer to a view controller. Later on, I use a delegate method to release editForm when the user taps the button to close the view.</p> <pre><code>@implementation EditViewController EditFormViewController *editForm; [...] (void)openeditform:(NSString*)editId { editForm = [[EditFormViewController alloc] initWithNibName:@"EditFormView" bundle:nil editId:editId]; [...] </code></pre> <p>The problem is, the view will often need to be recreated with a fresh slate. Is there a way to release the controller while keeping the empty pointer ready for future instantiations? Or a way to redeclare the "EditFormViewController *editForm;" statement from within a method?</p> <p>Edit, here's the full openeditform method:</p> <pre><code>- (void)openeditform:(NSString*)editId { EditFormViewController* editFormController = [[EditFormViewController alloc] initWithNibName:@"EditFormView" bundle:nil editId:editId]; [editFormController.view setFrame:CGRectMake(0, 0, 640, 460)]; [self.view addSubview:editFormController.view]; editFormController.delegate = self; [UIView beginAnimations:@"editform view open" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view.superview cache:YES]; [editFormController.view setFrame:CGRectMake(0, 0, 320, 460)]; [UIView commitAnimations]; self.editForm = editFormController; [editFormController release]; } </code></pre> <p>For Jerry Jones, here are the bits relevant to the removal of the view.</p> <p>EditFormViewController.m:</p> <pre><code>- (void) closeEditForm { [UIView beginAnimations:@"editform view close" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view.superview cache:YES]; //[UIView setAnimationDelegate:self]; [self.view removeFromSuperview]; AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; [appDelegate reloadEditViewTable]; [UIView commitAnimations]; [delegate didDismissEditFormView]; } </code></pre> <p>And the delegate method, which is currently not being used for anything, since I implemented Estarriol's suggestion, which isn't fully doing what I want it to do yet:</p> <pre><code>- (void)didDismissEditFormView { NSLog(@"Fired delegate."); //[editForm release]; } </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.
