我的UIImagePickerController中的单元格上显示了黑色背景

这是我的演讲方式。这里没有火箭科学:

    let imagePicker = UIImagePickerController()
    imagePicker.allowsEditing = false
    imagePicker.delegate = self

    imagePicker.modalPresentationStyle = .Popover
    imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    imagePicker.popoverPresentationController?.sourceView = self.view;

    presentViewController(imagePicker, animated: true, completion: nil)

显然,我只想要白色背景….?

作为将来的参考,此应用程序使用的是外观管理器,并已将所有UITableViewCells全局设置为黑色,如下所示:

UITableView.appearance().backgroundColor=.blackColor()
