Custom UIActivity : image icon inverted color

Question

For Custom UIActivity, activity image icon color is inverted,which is supposed to be in black and white. Please suggest me the answer.

My code to add image:

- (UIImage *)activityImage {
    return [UIImage imageNamed:@"openWith.png"];
}

Answer 1

That is the expected behavior. Probably Apple wanted to differentiate between default share apps and custom activities. That's why may be they have done so.
