At canEditRowAtIndexPath Method, reloadData of UITableView not work properly?

Question

In my application, I reload my TableView ([tablView reloadData];) after delete row from TableView then canEditRowAtIndexPath Method alway

Answer 1

When it comes to me, I analysed as below:

As commented by rmaddy on Nitin Gohel's answer:

1. You should always remove the data from the data source before updating the table.

   I feels this is the ideal way.

2. If you are going to call reloadData, there is no reason at all to first call deleteRowsAtIndexPath.

   This is also looks correct.

I analysed ambiguity, if I write reloadData its crashishing but once I write deleteRowsAtIndexPath it worked well.

Hope someone will emphasise on this issue for its causes etc.
