key: The key whose status you want.
error: If the status of the value for the key is AVKeyValueStatusFailed, upon return contains an NSError object that describes the failure that occurred.
Returns the current loading status of the value for key. For possible values, see "Protocol Methods."
You use this method to determine the availability of the value for a key. This method does not cause an asset to load the value of a key that's not yet available. To request values for keys that may not already be loaded without blocking, use loadValuesAsynchronouslyForKeys and wait for invocation of the completion handler to be informed of availability.
