横向模式下UINavigationBar的自定义背景 [英] Custom background for UINavigationBar in landscape mode

问题描述

我正在为我的UINavigationBar添加自定义背景。只要手机处于纵向模式，它就可以正常工作。一旦我切换到横向模式，一半的条形显示为蓝色（默认的导航栏颜色），其中一半有我的图像

I am adding a custom background for my UINavigationBar. It works fine as long as the phone is in portrait mode. As soon as I switch to landscape mode, half the bar appears blue (the default navbar color) and half of it has my image

如何拉伸图像以获得横向模式并在肖像模式下再次缩小？

How can I stretch the image for landscape mode and make it small again for portrait mode?

谢谢
