objective c - NSInternalInconsistencyException', reason: 'attempt to insert row 0 into section 0, but there are only 0 rows in section 0 after the update'

Question

I am using UITableViewController and getting this error while updating tableView. Below is my code:

This occurs when i do a click event:

[timeZoneNames insertObject:@"HELLO" atIndex:0];  
[self.tableView beginUpdates];   
NSArray *insertIndexPaths = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:0 inSection:0]];
[self.tableView insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationTop];
[self.tableView endUpdates];

I tried looking for apple documentation but that didnt helped.

Thanks, Aby

Answer 1

I ran into this error when I forgot to set the datasource outlet properly.

If you see this error, check that you have explicitly set your TableView delegate and datasource :

• go to your interface builder and look at the view with the 'Table View'

• cmd + right click drag ( you should see a blue line ) from the 'Table View' icon to the title icon for the file, this has a yellow icon next to it in xcode 6.

• release your mouse , you should see delegate and datasource options.

• select 'datasource'

your table should now be correctly wired.
