FWIW,我在尝试在ActivityItems数组中包含UIImage时遇到了同样的问题.它不适用于通用的UIImage,也不适用于使用UIImage + animagedGIF类别的UIImage,也不适用于FLAnimatedImage.

要解决此问题,至少在iOS8上,只需将gif作为NSData对象而不是UIImage添加到ActivityItems数组中.

例如,假设从URL请求gif:

NSURL *imagePath = [NSURL URLWithString:@"http://i.imgur.com/X4oonnm.gif"];
NSData *animatedGif = [NSData dataWithContentsOfURL:imagePath];
NSArray *sharingItems = [NSArray arrayWithObjects: animatedGif, nil];

UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil];
