intercept. If you do this, you are tinkering with the runtime, so
be careful - you'll want to make sure and implement forward:: to
send any unrecognized messages through to a "real"
NSURLCredentialStorage. I'm not a runtime expert, so I don't know
what all the gotchas are, just that there are more than a few.
I figured out how to do it with a category (see below). You just
need to call initializeDefaultCredentials() early on, in main() or an
+initialize method. The only downside is a category can only
override a method and cannot call the original NSURLCredentialStorage
methods. You'd have to do class posing or method swizzling to do
that. Also, I didn't have to override credentialsForProtectionSpace:
and setCredential:forProtectionSpace:, as I didn't see them being
called in my app.
