ABPeoplePickerNavigationController + pnetworkingicateWithBlock | choque

Obtuve mi propio controller PeoplePicker que se henetworkinga de ABPeoplePickerNavigationController . Estoy intentando establecer un NSPnetworkingicate para self.pnetworkingicateForEnablingPerson usando preidcateWithBlock así:

 self.pnetworkingicateForEnablingPerson = [NSPnetworkingicate pnetworkingicateWithBlock:^BOOL(id evaluatedObject, NSDictionary *bindings) { return YES; }]; 

y se bloquea con el error:

** Finalización de la aplicación debido a la exception no detectada 'NSInvalidArgumentException', motivo: 'NSBlockPnetworkingicate no puede codificarse ni decodificarse'
