If I write a framework that gets information from the Internet, should I make a degelate or use blocks?

Say I'm writing a publicly available framework for the Vimeo API. This framework needs to get information from the Internet. Because this can take some time, I need to use threadin to prevent the UI from hanging. Foundation uses delegates for this, like NSURLConnectionDelegate. However, Game Kit uses blocks as callback functions.

What is the recommended way of doing this? I know blocks aren't supported in standard GCC versions, but they require less, much less code for the one that uses my framework.

Delegates, on the other hand, are real methods and when protocols are used, I'm sure the methods are implemented.

Thanks.
