What is the best approach to check if the current gps location is within the extent of the map, before switching on the gps and auto pan? For example, if the base map I???m using only has data for Singapore, and if someone launches this app outside the country, how do I detect it? I understand one of the approach is to check the extent and gps coordinates manually, is there a better solution to tackling that?

Have you initialized the Graphics Layer and add it to the map before you execute those statements? You will need to execute the following first: AGSGraphicsLayer* graphicsLayer = [AGSGraphicsLayer graphicsLayer]; [self.mapView addMapLayer:graphicsLayer withName:@"GraphicsLayer"]; The name should match what your codes attempt to retrieve.

If you are using the final version of ArcGIS API for iOS 1.0, you will need to replace infoTemplate with infoTemplateDelegate AGSGraphic* myGraphic = [AGSGraphic graphicWithGeometry:myMarkerPoint symbol:myMarkerSymbol attributes:nil infoTemplateDelegate:nil];

Are there any ways to add animated markers to the map? Or animate the way the makers appear on the map?

What is the best approach to find and retrieve a list of features within a radius of xx meters, based on either my current location or a location on the map? One approach is to retrieve all the features and perform the distance calculation and filtering using in the iPhone application itself, but this is rather inefficient and cpu intensive.

We are working on to support iOS4. Stay tuned! 🙂 Will the new beta sdk with support for the iOS 4 be released before the ESRI User Conference 2010?

Having cached tiles would indeed be valuable. For example, a Parks application which uses the map and overlays information such as foot paths, restrooms, attractions etc. In this case having cache would mean less reliance on the data network, resulting in faster loading times too. That would be an added benefit for iPod Touch users as well, who can first browse the area they intend to visit while connected, so that they can still view the map while at the park, where there is no WIFI as well.
