Cannot set delegate to BufferedNavigationController

[ajonnet]

BufferedNavigationController seems to be using delegate property itself. So, upon setting up a delegate to it, it does not do any transition.

@ajonnet this can be fixed by creating a Proxy and setting it as a delegate. The proxy will forward invocations to all of the real delegates

@Usipov, that is what i had did at that time. To what i remember, i put it as an issue here because i believed that it should be handled internally, so the experience of anybody using the library should be transparent.
