Let me ask a few stupid questions, because sometimes stupid questions can be helpful: 1) You want to make an app that lets the user post messages on twitter, right? 2) When URLs are posted on twitter, they are automatically shortened to some bit.ly or similar type of address, right? Or are you planning to do the shortening yourself? 3) You want to determine in advance whether an URL will be shortened, right? Perhaps to give better feedback to the user about how many characters the user has left? I say this is impossible to do perfectly, unless Twitter has some special service for developers who struggle with this problem. Perhaps they have some http-based interface to determine if an URL will be shortened, I don't know. Perhaps they have a specification of how they determine what URLs to shorten. There has been some discussion about whether to do a DNS lookup. There are good reasons to avoid it, but any solution will have its flaws anyway. How about you start with a valid URL, then you introduce a spelling error in the host name, and use the "host" command, or "nslookup" from terminal to determine that the new host name really is unregistered. Then you type in your full URL including typo into your reference app, and see whether it is interpreted as a URL that can be shortened. Then you'll know whether that app does use DNS lookups to determine it. Apart from that, since you haven't seen a satisfactory response on the list yet, I think there is no Cocoa-specific solution. Therefore I think you will get better help in a more general technical forum, such as stackoverflow.
