What's the meaning of -forwardSignalWhileActive: ?

[limboy]

don't quite get the idea. can't we just do

[[self didBecomeActiveSignal] subscribeNext: ^(id x)];

[jspahrsummers]

-forwardSignalWhileActive: will subscribe to a signal when the view model becomes active, and dispose of that subscription when it becomes inactive. This means that work can easily be started and canceled in accordance with the view model's active state.

Also, anything that avoids explicit subscription is a good thing.
