The problem is caused by your dispatches. They're never cancelled. You should look into starting to use NSOperation and NSOperationQueue when the cell is being reused, cancel the operation it was performing.

I think You should load image asynchronously and save that in cache.For that there is so many third party source available. I found this are the best of them-

1.https://github.com/nicklockwood/AsyncImageView 2.https://github.com/rs/SDWebImage
