我正在尝试将UIPopoverView添加到我的Swift iOS 8应用程序,但我无法访问PopoverContentSize属性,因为popover没有显示正确的形状.我的代码:

var popover: UIPopoverController? = nil

    var newCategory = storyboard.instantiateViewControllerWithIdentifier("NewCategory") as UIViewController
    var nav = UINavigationController(rootViewController: newCategory)
    popover = UIPopoverController(contentViewController: nav)
    popover!.setPopoverContentSize(CGSizeMake(550, 600), animated: true)
    popover!.delegate = self
    popover!.presentPopoverFromBarButtonItem(self.navigationItem.rightBarButtonItem, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}

func addCategory() {

    var popoverContent = self.storyboard.instantiateViewControllerWithIdentifier("NewCategory") as UIViewController
    var nav = UINavigationController(rootViewController: popoverContent)
    nav.modalPresentationStyle = UIModalPresentationStyle.Popover
    var popover = nav.popoverPresentationController as UIPopoverPresentationController
    popover.delegate = self
    popover.popoverContentSize = CGSizeMake(1000, 300)
    popover.sourceView = self.view
    popover.sourceRect = CGRectMake(100,100,0,0)

    self.presentViewController(nav, animated: true, …
