How can I know the currently displayed page on iOS5?

I know I can use RAPageCollectionViewController and then displayIndex, but this it's not working on iOS5.
Thanks

Try looking for a private -currentViewController in the for-subclasses header. It should do what you do — but monitoring it is another story. You can hook into the appropriate layoutSubviews call and query the current view controller after calling into super to see if things have changed.
