You don't say what methods of NSFileHandle you're using to read the data. In particular, some of the asynchronous methods require that you re-issue the request to keep reading. For example, -readInBackgroundAndNotify will post an NSFileHandleReadCompletionNotification notification when it reads _some_ data. In your handler for that notification, you must repeat the -readInBackgroundAndNotify invocation to read more data. You will know you've read to end-of-file (or closing of a communications channel) when you receive an empty data object in that notification.
