iOS TableView move and will be crash when reload data ?

[anim510]

Hi all,

I use the tableView to show my records, and i use this function to move the rows.

- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath

It's will be crash every time when i move the rows, if i call this function.

[myTableView reloadData];

It's will be duplicate if i don't reload data, and it's never be crash.

Has anyone can help me ? Thanks very much.

regards,
Neil

Error ..

The error is:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray insertObject:atIndex:]: index (3) beyond bounds (1)'

This means that your data array only contains 1 item, but you're trying to read item 3 (which doesn't exist) and it's causing your app to crash.

You need to check the parts of your code where you add and read data and ensure that you're never reading data before you've added it.
