Vertical UISlider in .xib for custom class?

I'm trying to create a reusable custom view class with a .xib file laying out a few buttons and a vertical slider. I know that I can programmatically rotate a UISlider in the class file with 

slider.transform = CGAffineTransformMakeRotation(CGFloat(M_PI * 3.0 / 2.0))

and if my class is @IBDesignable I can see the vertical slider in the main StoryBoard, but is it possible to see the vertical slider in my .xib file layout?

The precise answer is NO. But there is a workaround to this. Follow these steps.

 1. Create a slider 

 2.Show the "Identity Inspector"

 3.Add a "User Defined Runtime Attribute"

 4.Set the key path to "layer.transform.rotation.z", the type as "String" ("Number" won't allow floating point values) (possible since Xcode 5) and the value to "-1.570795" (-π/2).

Unfortunately, it will still appear as horizontal in Interface Builder.

But you can position the center and don't need to create a custom class, so it might be useful enough in some cases.
