旋转 UIBarButtonItem

问题描述

我想旋转一个 UIBarButtonItem.

我已经能够使用 setTransform:CGAffineTransformMakeRotation(…) 对 UIButton 执行此操作，但 UIBarButtonItem 没有此属性.

I have been able to do this with UIButtons using setTransform:CGAffineTransformMakeRotation(…), but UIBarButtonItem does not have this property.

我知道相机应用可以做到这一点，所以它应该是可以实现的.
我怎样才能做到这一点?

I know the Camera-app does this, so it should be achieveable.
How can I achieve this?

谢谢.

推荐答案

您是否尝试过在 UIBarButtonItem 中使用自定义视图，然后以任何您想要的方式进行转换?

Have you tried using a custom view inside the UIBarButtonItem that you then transform any way you want?
