There is an serious bug resulting game crash while loading an AssetBundle by WWW www = new WWW(url) ; We have purchased Unity 4.0 and hope anyone can support us for our project.

The project is build in the Unity 4.0, it runs well on IOS 5.0+, but it crash on IOS 4.3.3 and IOS 4.3.5(compiled with xcode 4.5.1).
We have tested with the official AssetBundles example, and the official example also crashed on iOS 4.X version

I had the same problem and it was because of too many ‘/’ characters when loading ‘file://’ URIs on iOS.

This page helped:

Notes http://, https:// and file:// protocols are supported on iPhone. ftp:// protocol support is limited to anonymous downloads only. Other protocols are not supported.

Note: When using file protocol on Windows and Windows Store Apps for accessing local files, you have to specify file:/// (with three slashes).

Thanks! :slight_smile:
