I have a local geodatabase in my app, and the user can choose an envelope/extent across which to bring down data from the live server.
But if I then want to pull down a second data set from a different envelope, the first data set gets erased. Seems I can only hold one envelope of data at a time.
I'm using this call: generateGeodatabaseWithParameters with useExisting set to YES. Every time I run the generate call, existing data gets removed.
Any ideas? I need to have the user pull down data in chunks. Thanks for any thoughts,
