Is there a way to retrieve the custom labels that the user has created for CNContact properties in iOS? I know that properties of CNContact objects are often of the generic type CNLabeledValue. The label property of that type of object gives the label portion of the object.
Here is a two screenshots of my iPhone screen showing the UI for creating a custom label. As you see in the first screenshot, it says "Add Custom Label" to allow the user to create a custom label for phone number properties. In the second screenshot, the UI is allowing the user to create the custom label.
