ios - 关闭 PopOverViewController 时黑色闪烁

我在关闭 PopOverViewController 时出现黑屏。

ViewController.swift 中的代码

 if segue.identifier == "addComment"
    {   
               let controller = segue.destinationViewController as! ProfileCommentPopOver
                controller.popoverPresentationController?.delegate = self
                controller.preferredContentSize = CGSizeMake(250, 150)
               controller.fetchedProfileID = sendToUserID
        }

PopOverViewController.swift

 @IBAction func addCommentAction(sender: UIButton)
{
                    self.dismissViewControllerAnimated(true, completion: nil)

}
