How to download a Private gallery image

jiminy

I have oauth 1.0a functioning. I can get the list of galleries and images in a private gallery. However I cannot seem to actually GET an image from a private gallery. In my IOS app i am returned an authentication challenge. On the original GET request I have include the Authorization header with oauth_token, oauth_nonce, oauth_signature, oauth_consumer_key, oauth_timestamp, oauth_version, oauth_signature.

Am I missing something obvious? The fact that oauth works well enough to list the gallery contents is encouraging, but I don't understand what I am missing on the actual image download.
Galleries that are marked simply as unlisted download fine.

Any help appreciated.

Never mind, I figured it out. I had a small error in my Authorization header when attempting to download an image. Once I made a change to correct that problem it works fine. I think the authentication challenge was unrelated, and I just commented out the callback for that, allowing iOS to perform it's default processing. All it working now.

Just to be thorough here, I should point out that if you get redirected, you need to build a new NSURLRequest with the Authorization header again otherwise you will fail on a 404 error. In my case that meant handling the Delegate callback at willPerformHTTPRedirection, building a NSURLRequest object with the new redirected url and Authorization hdr, and then calling the completion function with the new request.
