Hi (again) everyone,

It seems that each day I have a new question about STV, but hopefully this one is easy to solve.

I have two related Core Data entities. The "Field Data" entity contains the "Data" attribute, which stores the actual data. This is related to the "Field Name" entity which contains the "Name" attribute (which is the name of the field) and the "Order" attribute (which allows for the ordering of the fields). This is setup so that I don't need to repeat the name of the field in each "Field Data" object but can instead simply relate that object to the relevant "Field Name" object.

In STV I have setup a SCClassDefinition for both the Field Data and Field Name entities. The Field Data objects display in the root STV and the user can then tap the cell to view the detail edit view and change the Field Name. I have been able to traverse the relationship and display the field name in the root STV by using the following code: fieldDataDefinition.titlePropertyName = @"fieldName.name";. However, doing the same for the keyPropertyName (so that I can order the objects based upon the order attribute in the related entity) does not work: fieldDataDefinition.keyPropertyName = @"fieldName.order";

Is there a way to traverse the relationship for the .keyPropertyName attribute so that I can custom order the objects / cells based upon an attribute in a related entity?

Thanks,
Matthew

Hi Matthew,



Thanks a lot for all your questions, we (and I am sure a lot of other users too) learn tremendously from them.



We will do our best to add this feature to our next STV 2.0 release, due in less than a couple of weeks. Thanks Matthew

Great Thanks Tarek!

Does this work now?

Hi Andrew,

Yes this should work now, as STV currently uses key paths to fetch the property values.
