UIPopoverController can't handle ui elements
===

I present Popover in some function (for example print) when I tap on button. But when my view controller appear in popover I can't handle any UI controls.

There is my code: 

    PrintViewController *option = [[PrintViewController alloc] init];            
    if (!popoverController) {
       popoverController = [[UIPopoverController alloc] initWithContentViewController:option];
    }
    popoverController.delegate = self;
    [popoverController setPopoverContentSize:CGSizeMake(700, 400)];
    [popoverController presentPopoverFromRect:((UIButton *)sender).bounds inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
