Here's the screenshot:
In my subclass of UIActivity, I override the -activityImage method to use my own icon for the facebook share item, but it appears in the share panel but disappears in the MORE list.

Quite old question, but maybe the solution is helpful for others too!
In your UIActivity subclass implement/overwrite the method
- (UIImage *)activityImage {
return [UIImage imageNamed:@"Activity Icon"];
}
to return the image to be shown in the UIActivityViewController itself (as you've done).
In addition to this implement/overwrite the method
- (UIImage *)activitySettingsImage {
return [UIImage imageNamed:@"Activity Settings Icon"];
}
to return an(other or the same) image to be shown in the more/settings view.

Have you checked that your image has this format
For iPhone and iPod touch, images on iOS 7 should be 60 by 60 points; on earlier versions of iOS, you should use images no larger than 43 by 43 points. For iPad, images on iOS 7 should be 76 by 76 points; on earlier versions of iOS you should use images no larger than 60 by 60 points. On a device with Retina display, the number of pixels is doubled in each direction.
