using GIFU type "ImageView" causing random gifs

[iosdev4rnd]

hi, i am using collectionview to show gifs and images mix. problem is the gif came from the url goes to random cells. i have used prepareForReuse() as well... but no benefit. can you please tell me workaround or what i am doing wrong in it or its library issue ?

further more if i scroll collectionview, it will reload all the images, and there is few seconds gap in display the gif again.
