Question

I have a UITableView with some sections and rows.

I want to move one row from one section to another section, when I call a function (so not my fingers and I do not want use edit mode of UITableView).

How can I do this?

If I recreate a datasource and reload table, it’s ok, but it not use animation.

Answer 1

UITableView offers you methods for this:

call beginUpdates, update your datasource, call moveRowAtIndexPath and finally call endUpdates on UITableView

[tableView beginUpdates];

// update your datasource
// ... 

// fill in your indexpath of old and new position
[tableView moveRowAtIndexPath: ... toIndexPath: ...];
[tableView endUpdates];

EDIT: moveRowAtIndexPath is only for iOS 5+
so you would rather use this:

[tableView insertRowsAtIndexPaths: ... withRowAnimation:...];
[tableView deleteRowsAtIndexPaths: ... withRowAnimation:...];
