I found an issue in the code that you kindly share with us.

Using your original code, I did an adaptation for use in my app. My app uses WebServices and show the results of my query in a tableview.

However, if I have 2 or more records (tableviewrow) shares Confirm and Cancel function successfully. But if I have only one record (tableviewrow) code displays the following error, which I accompany with a picture.

Likewise, I did check with the code that you provide and the same case.

I will appreciate all your possible support and greetings from mexico

Hi almsx.

This is because first delete the row, and when you try to read it no longer exists, it is solved very easy just to limit it.
I put the solution here taking the original code here.
