I am trying to update an existing record on the client database. The existing record has a uuidtext column with an existing value, and I want to remove that value and set the record's column to null. To accomplish this I am grabbing the original record from the table as an AGSGDBFeature, and then updating the keys using setAttributeToNullForKey:.
What I have found is that when I send setAttributeToNullForKey: to AGSGDBFeature, the method simply removes the key altogether. In turn, when I send saveFeature:error: to AGSGDBFeatureTable, the missing key means the column is not updated. According to the documentation, setAttributeToNullForKey: should set the key to NSNull, not remove the key altogether.
How can I remove an existing value from a record?
Our SDK version is 10.2.5.
This behavior is consistent across all of our iOS devices and versions.
