I'm following some of the samples for creating a new AGSMap instance from a web map. This works fine except that filters on layers in the web map are not honored or used. My web map basically contains a layer that has a filter expression that limits features to a single floor within a building. When viewed on the web, the web map works fine. However, used within the iOS 100.0.0 SDK, features from all floors within the building are displayed.
Any help appreciated!
