UITableView的moveRowAtIndexPath的代码

暂时只是实现同一个section里的移动，要跨section移动的话，稍微懂点脑筋就行～

代码：

1. - (void)tableView:(UITableView *)tableViewmoveRowAtIndexPath:(NSIndexPath *)fromIndexPathtoIndexPath:(NSIndexPath *)toIndexPath {
2.     if (fromIndexPath != toIndexPath) {
3.         id object = [self.dataMutableArray objectAtIndex:fromIndexPath.row];
4.         [object retain];
5.         [self.dataMutableArray removeObjectAtIndex:fromIndexPath.row];
6.         if (toIndexPath.row > [self.dataMutableArray count]) {
7.             [self.dataMutableArray addObject:object];
8.         }
9.         else {
10.             [self.dataMutableArray insertObject:object atIndex:toIndexPath.row];
11.         }
12.         [object release];
13.     }
14. }
15.  
16. - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
17.     return YES;
18. }
