UIDocumentsInteractionController shows iBooks but doesn't open it

Question

My UIDocumentsInteractionController is working as far as presenting an action sheet with a button that says "iBooks" but when I click on that button, it just dismisses and it doesn't take me to iBooks. Here's my code:

NSString *filenamePath =[NSString stringWithFormat:@"temp.%@", [[file path] pathExtension]];

    NSString *docDir = [DataCenter getDocumentsDirectoryPath];

    NSString *fullPath = [docDir stringByAppendingPathComponent:filenamePath];

    NSURL *url = [NSURL fileURLWithPath:fullPath];
    UIDocumentInteractionController *c = [UIDocumentInteractionController interactionControllerWithURL:url];

    BOOL success = [c presentOpenInMenuFromBarButtonItem:buttonBack animated:YES];

What am I doing wrong? Thanks

For those stuck at this: You don't need to set yourself up as UIDocumentInteractionController's delegate at all.

Problem was [UIDocumentInteractionController interactionControllerWithURL:url] is being autoreleased. It thought it would be retained internally by the action sheet being shown but apparently it's not. So yea, gotta retain it until action sheet dismisses.
