No of UIWindow instances in an iPhone App

Question

Can some one confirm me that only one UIWindow instance is possible in any iPhone Application at any time?

UPDATE: I found the following information in this link . According to this there can be many windows.

In addition, the UIApplication object maintains a list of all the windows (UIWindow objects) currently open in the application, so through those it can retrieve any of the application’s UIView objects.

Answer 1

That's my understanding. But I could be wrong :-)

Answer 2

Yes for iOS aps there is typically only one UIWindow..
