-------------------------------------
[~voliva] Thanks, I have merged your change, which fixes older versions of
cordova-ios, however, in order to patch master, I need to do more testing.
Can you provide some basic simple test code that demo's the issue?
I tried xhr loading an image and creating a blob from it's bits which works
great for adding to an img.src, but does not appear to load into an iframe.src
( maybe the blob is not allowed to be shared between 2 windows ... )
A simple example would be awesome, thanks again for your contributions.
> Blob schemes won't load in iframes
> ----------------------------------

> Key: CB-9558
> URL: https://issues.apache.org/jira/browse/CB-9558
> Project: Apache Cordova
> Issue Type: Bug
> Components: iOS
> Affects Versions: 3.9.0
> Reporter: Víctor Oliva Vidal
> Assignee: Jesse MacFadyen
> Priority: Minor
> Labels: cordova-ios-4.0.x
>
> Blob schemes won't load in iframes, even though blob:* is whitelisted.
> This is needed for special cases, like when using an epub reader
> ([ePub.js|https://github.com/futurepress/epub.js/]), that downloads an epub,
> extracts it to a blob and displays it in an iframe.
> This currently works perfectly in cordova-android, but not in cordova-ios.
> I've debugged why it happens... the Whitelists says the scheme is allowed and
> the URL is allowed, but then
> {code}
> [NSURLConnection canHandleRequest]
> {code}
> returns false, thus cancelling the request. Hardcoding "blob" as an allowed
> scheme (like it's currently done with mailto, tel and sms) fixes this issue.
> I was about to put a pull request in github when I saw your contributing
> guidelines.
