Classification:UI/Usability Reproducible:Always
 
Summary: When subclassing UIActivity, it is necessary to return a UIImage for the activityImage. However, no matter what icon you return, the icon for the activity in the UIActivityViewController remains white.

Steps to Reproduce: Create a custom UIActivity subclass. Return any image for -[UIActivity activityImage]

Expected Results: When presenting a UIActivityViewController with the custom UIActivity, the custom UIActivity's icon will match the icon you returned.

Actual Results: The icon remains white.

Regression: Happens on both iPad and iPhone.

Notes: The sample app included is also included with other bug reports, so to test this bug simply tap the action button at the bottom of the screen and a UIActivityViewController will appear that has a white icon when it should be a custom icon.

Comments

This is intentional

Apple updated their docs: http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIActivity_Class/Reference/Reference.html#//apple_ref/occ/instm/UIActivity/activityImage

Quote: " Any color data in the image itself is ignored. Opaque pixels have a gradient applied to them and this gradient is then laid on top of a standard background. "
