The method name doesn't sound good.

Why don't reuse "didReceiveData" and clarify that data could be null?

[yusukesuzuki, 2013/09/19 05:13:58]

Since didDownloadData always has no data, I think that clarifying it by function
signature is better.
But reusing "didReceiveData" and adding comment about that is also reasonable.

[yusukesuzuki, 2013/09/19 05:33:06]

Is it more preferable reusing "didReceiveData"?

[yusukesuzuki, 2013/09/19 15:41:21]

Done. Thanks for your suggestion.
