Subject [jira] [Created] (CB-9558) Blob schemes won't load in iframes
Date Wed, 26 Aug 2015 13:54:45 GMT
Víctor Oliva Vidal created CB-9558:

             Summary: Blob schemes won't load in iframes
                 Key: CB-9558
             Project: Apache Cordova
          Issue Type: Bug
          Components: iOS
    Affects Versions: 3.9.0
            Reporter: Víctor Oliva Vidal
            Priority: Minor

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
[NSURLConnection canHandleRequest]
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.
