Cocoa - connection:didFailWithError error codes

Where can I find the error codes and their meaning that connection:didFailWithError method can 开发者_C百科give ?

Here's a full list of the currently supported error codes for NSURLConnection.

Can't post the full list of all the error codes here since there are new ones for iOS 5.0 and that is still under NDA. Go to Spotlight and search for NSURLError.h. Open it in Xcode and you can see the full list.
