Is NSTextAttachment image animation possible?

Question

Using iOS7 I'm able to display images in a UITextView with no problem using NSTextAttachments. However, is it possible to show animated images in a UITextView using NSTextAttachments? If so, how?

Answer 1

To animate images in NSTextAttachment you need to attach a CADisplayLink to the UITextView and change the images manually. After that you should call layoutManager.invalidateDisplay(forCharacterRange: ATTACHMENT_RANGE) to refresh the textView layout
