Question

For a simple example of using a NSMutableArray of strings called rows, what do I have to implement in my table controller to move the tableView rows and have the changes reflected in my array?

Answer 1

Here we do our heavy lifting.

 - (void)tableView:(UITableView *)tableView  moveRowAtIndexPath:(NSIndexPath *)fromIndexPath         toIndexPath:(NSIndexPath *)toIndexPath  {     NSLog(@'move from:%d to:%d', fromIndexPath.row, toIndexPath.row);     // fetch the object at the row being moved     NSString *r = [rows objectAtIndex:fromIndexPath.row];       // remove the original from the data structure     [rows removeObjectAtIndex:fromIndexPath.row];      // insert the object at the target row     [rows insertObject:r atIndex:toIndexPath.row];     NSLog(@'result of move :\n%@', [self rows]); } 

Since this is a basic example, lets make all the rows moveable.

- (BOOL)tableView:(UITableView *)tableView  canMoveRowAtIndexPath:(NSIndexPath *)indexPath {     return YES; }
