Answer 1

One cause for those searcing on the question in the title:

This problem can occur if you have a bad iOS cable connected. The cable could work perfectly normal but in some angles when twisted and turned , could fail and lose connection.

Second cause (Your cause):

I swipe the tableview

Something in your tableView is not set up correctly. Probably as mentioned in the comment section below your question, memory issues. Add code to your question for us to be able to check even further in detail.

Answer 2

It's a memory issue. The system kills the app while it's going to load to many images. I commented the code "decodedImageWithImage" in SDWebImage, And the problem got fixed.
