Okay..let???s look at one issue at a time. You can create new thread for other issue. By looking at the code???there are few issues. 1. You are setting up your map view ([self setupMapView:YES]) in videDidLoad and immediately creating an envelope with self.mapView.spatialReference for zoom function. It may happen that spatialReference of the mapView will be nil as map view may  or may not be loaded. If you want to do this then you should not rely on self.mapView.spatialReference and provide known spatial reference or you should move this code in the mapViewDid load where you know that self.mapView.spatialReference has valid spatial reference as map view successfully loaded. 2. You are observing MapDidEndZooming  notification and in respondToZoomlevelChange you are keeping a copy of self.mapView.visibleArea.envelope without checking whether it???s not-nil/valid envelope or not. 3. Immediately you are checking some condition and if it???s true then you are resetting the map view. Again, you are using the self.mapView.spatialReference  in the AGSGeometryEngine???s  projectGeometry method without verifying whether spatial reference is valid or not. You should use mapView???s properties only when you are confirm whether map is loaded successfully. Hope this helps! Regards, Nimesh ... View more
