There isn't enough information for me to figure out your main problem, but I
think I know this one.

I bet that newWithInteractors: does not actually create an instance of
SDRButtonContainer.  You say it "ismply has a class initialise" so I think
you are just storing the arguments in a variable of the class, but do not
actually create an instance of the class.  Note that SDRButtonContainer is a
class, it is not itself a SDRButtonContainer.  So, it has not instances and
allInstances SHOULD return nothing.

In general, we will need more info to debug this.  Give more code.
