问题描述
有没有办法在iOS8上简单地更改UIPopoverView背景颜色（包括它的箭头）？
Is there a way to simply change the UIPopoverView background color (including its arrow) on iOS8?
（我确实读了一对有关自定义UIPopoverControllers的文章。这是否适用于此，意味着答案是否？）
(I did read a couple of articles on customizing "UIPopoverControllers". Does this apply here too, meaning the answer is "no"?)
这不是我应该能够在 prepareForSegue中解决的问题触发popover的方法？如何才能到达相应视图以更改其外观？
Isn't this something I should be able to address in the prepareForSegue method triggering the popover? How can I reach the according view to change its appearance?
推荐答案
我找到了解决方案。 iOS8不再需要子类化了！可以在tableview - > navigation - > popoverPresentationController
I found the solution. Subclassing is not necessary anymore with iOS8! The background can be accessed and changed like this from within the tableview -> navigation -> popoverPresentationController
self.navigationController?.popoverPresentationController?.backgroundColor = UIColor.redColor()
