I need to download an image from the web and display it in an ImageView. Presently I am using SDWebImage (It is an asynchronous image downloader with cache support, with a UIImageView category).

But it crashes when I click the back button and forward button (when I try to go back and forth of the view repeatedly). Anyway this happens very rarely, but I need to get rid of this bug. Is there any other library (that does not use private API’s) that I could use in my project?

    Yes. You can user other libary. I’ve already implemented that using AsyncImageView which is inherited from UIImageView. What it does is it stores images in Cache memory fetched from a url and whenever you need to load image from the same URL again it will simply load it from the cache memory saving a lot of time.

    Just follow the link for implementing that:

    Please have a look at the image showing the technique I’ve implemented. It lets you do other activity while images are loading.:
