iOS 上方向改变时的非旋转背景图像
我正在开发一个 iPhone 应用程序，它允许纵向和横向方向。但是，我在 UIImageView 中有一个背景图像，当方向改变时不应旋转该背景图像。我四处搜寻并尝试了一些选项，但没有找到令人满意的解决方案。我尝试在 willAnimateRotationToInterfaceOrientation: 中使用变换，但它使图像在旋转过程中移动，并且看起来不太好。我希望它保持静止。
任何帮助表示赞赏。
I'm developing an iphone app and it allows for both portrait and landscape orientation. However, I have a background image, in an UIImageView, which should not be rotated when the orientation changes. I've searched around and experimented with some options, but have not found a satisfactory solution. I tried using transforms in willAnimateRotationToInterfaceOrientation: but it makes the image move during rotation, and doesn't look good. I would like it to remain stationary.
Any help appreciated.

也许尝试这个：
因为您的 appDelegate.window 不关心当前的设备方向，所以它可能是一个解决方案。我只是尝试在方法中的appDel.window中添加一个UIImageView
，正如预期的那样，它不会与上面的uiviewcontroller.view一起旋转
当然你也可以尝试addSubview：
Maybe try this:
as your appDelegate.window doesn't care about the current device orientation it might work out as a solution. I just tried adding a UIImageView to the appDel.window in the
method, and as expected, it does not rotate with the above uiviewcontroller.view
Of course you could also try addSubview:
