Summary:

UIWebView cannot load audio/video through a custom NSURLProtocol handler. All other web content I've tried (html, js, css & all images) load just fine via a NSURLProtocol handler. Video and audio will fail.

Steps to Reproduce:

1: Download provided project.
2: Note that a custom NSURLProtocol is being register and can handle URLs of the "x-file:" URL scheme
2: Note that a UIWebView is being created and told to load a request with a "x-file" URL.
3: Note that the .html web content loads just fine
4: Click on the links to play video inline, note that video fails to load.

Expected Results:

Video loads through my customized NSURLProtocol.

Actual Results:

Video fails to load. While the video does trigger a canInitWithRequest: message the video still does not load.

Regression:

N/A

Notes:

It seems that video/audio can only play via file: or http(s): urls. Custom URL schemes are not supported.

We ran into this bug as well. On advice of Apple Developer Support I have filed another bug report, 8692954.

Did you ever find a workaround?

ProtocolTest.zip (attached to original bug) available from http://dl.dropbox.com/u/26380/ProtocolTest.zip (possibly NOT permanently - get it while it's hot.)
