I assume you mean the black bar problem? It's a bug in iOS when you try to resize images client size. There's no workaround (besides disabling client-side image processing for iOS) AFAIK.
Yes that's the bug in question. There isn't really a fix for it, but a very very ugly workaround. Look at ios-imagefile-megapixel to see how they fixed it if you want. Or you can wait a few days for my implementation will be better documented.
