Subclassed UIViewController not binding its outlets

Hi

Have noticed this before but have just implemented another way but would really be good to be able to do this.

Have complex class A with a xib and lots of bindings.

Want to have simple class B that inherits from A but when it constructs in its fails to find any outlets defined in A so it throws an exception.

"Failed to find selector setCloseKeyboardButton: on Grocery.iOS.iPadSigninViewController"

Any ideas to resolve ?

thanks
