> ----------------------------------
>                 Key: CB-9558
>                 URL:
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: iOS
>    Affects Versions: 3.9.0
>            Reporter: VĂ­ctor 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|]),
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.
