Release iPad UipopoverController from its content controller

AddCategoryViewController* content = [[AddCategoryViewController alloc] init];
 UIPopoverController* aPopover = [[UIPopoverController alloc]< br /> initWithContentViewController:content];
 aPopover.delegate = self;
 [content release];

 // Store the popover in a custom property for later use.
 self.addCategoryPopover = aPopover;
 [aPopover release];
 [addCategoryPopover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

-(IBAction)saveAddCategory:(id)sender {
 if (rootViewController == nil)
 rootViewController = [[RootViewController alloc] init];

 [rootViewController.addCategoryPopover dismissPopoverAnimated:YES];
 [rootViewController dismissPopover];
}

aPopover.delegate = self;

So I have a popover with a button. When the button is pressed, I want the popup to disappear. It seems easy, but I can’t figure out my life. I use to display the popover The code is as follows:

AddCategoryViewController* content = [[AddCategoryViewController alloc] init];
 UIPopoverController* aPopover = [[UIPopoverController alloc]
 initWithContentViewController:content];
 aPopover.delegate = self;
 [content release];

 // Store the popover in a custom property for later use.
 self .addCategoryPopover = aPopover;
 [aPopover release];
 [addCategoryPopover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

In addcategoryviewcontroller, I have:

< p>

-(IBAction)saveAddCategory:(id)sender {
 if (rootViewController == nil)
 rootViewController = [[RootViewController a lloc] init];

 [rootViewController.addCategoryPopover dismissPopoverAnimated:YES];
 [rootViewController dismissPopover];
}

Rootviewcontroller is where popovers are created. Unfortunately, none of these methods solve it. Any help?

You will see a warning on this line.

aPopover.delegate = self;

If you want to execute your code. The application will crash. Instead, you need to be like this.
