I have a view between other views, the order may vary. For example: viewA on top of viewB, on top of viewC, or in another order.

Suppose I have

viewA, viewB, viewC, viewD and viewE

A is on the top and E on the bottom.

I need to replace viewC with viewZ, but I need to insert viewZ in the same index of viewC.

How do I know, before removing viewC, what index it has, so I can insert viewZ using

[self.view insertSubview:viewZ atIndex:?????)

and it will be at the same level?

thanks for any help.
