hasFetchedData

- (BOOL) hasFetchedData

readnonatomicassign

Indicates whether the attachment data has already been retrieved. Even if the data has been retrieved previously, you will still need to call fetchDataWithCompletion: to get the data, however that operation should complete quickly since the data is already available locally and so you can request it proactively. Otherwise, it could take some time to retrieve the data from its source, and you should fetch the data only when the user explicitly asks for it.
