Leaving swipe to delete button open on uitableview cell then going back causes crash

I have swipe to delete on one of my table cells. If I swipe right on the table cell to display the delete button and pop the view by pressing the back button the app crashes with Thread 1: EXC_BAD_ACCESS. I've already singled this out as the reason it crashes. Why does this happen?

This is what it looks like when I tap back https://www.dropbox.com/s/ggn4jqr0ox0tnta/Screenshot%202014-12-04%2023.39.25.png?dl=0

This caused because delegate and datasource of the table is simple assign pointer, not weak. So after deleting view controller, containing table still can send events to the controller. To avoid this you can manually set tableview delegate and datasouce to nil in dealloc method. BTW, this happens not only with tables.

When you are swiping right, may be you are popping the controller. Because the view is disappearing, you have to write NANNAV's lines.
