iOS开发学习之#表视图#（3）移动行

继续上篇接下来介绍移动行：移动行我们用

- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath

(UITableView *)tableView用来指定表视图，(NSIndexPath *)sourceIndexPath用来指定要移动行的索引路径，(NSIndexPath *)destinationIndexPath用来指定行移动到目标位置的索引路径

核心代码：

<pre name="code" class="objc">//移动行
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{
    NSInteger fromRow = [sourceIndexPath row];
    NSInteger toRow = [destinationIndexPath row];
    id object = [a objectAtIndex:fromRow];
    [a removeObjectAtIndex:fromRow];
    [a insertObject:object atIndex:toRow];
}
