I assure you that I did look for an answer in SO for my question but none of them were helpful. Here I got a simple code that should present a UIImagePickerController within a UIPopoverController:

-(void)takePicture:(id)sender{
UIImagePickerController *picker=[[UIImagePickerController alloc] init];
picker.delegate=self;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
picker.allowsEditing=YES;
UIPopoverController *poc=[[UIPopoverController alloc] 
                            initWithContentViewController:picker];
[poc presentPopoverFromBarButtonItem:bbItem 
            permittedArrowDirections:UIPopoverArrowDirectionAny
                            animated:NO];
}

Now, even from the first time I get [UIPopoveController dealloc] reached while... error and the program crashes. I'm not doing any retain,relase or autoreleases as per ARC. Is there any special consideration with UIPopoverControllers when benefitting from ARC?

UIPopoverControllers should always be held in an instance variable. It is a good practice to create a strong property for it.

UPDATE:

As of iOS 8 you should be using UIPopoverPresentationController. Then you don't need to keep a reference to the popover because it is managed by the presentation controller.

Code example (works both on iPhone and iPad):

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.allowsEditing = YES;
picker.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController* popoverPC = picker.popoverPresentationController;
popoverPC.barButtonItem = bbItem;
popoverPC.permittedArrowDirections = UIPopoverArrowDirectionAny;
[self presentViewController:picker animated:YES completion:nil];
