Question

I hava a tableview,and I will updata the data in the tableview.it receive datas every one second,when the data is received,it will replace the old data in one row.
I do like this:
when the data is received,i call

[m_tableView reloadData];

so,it will call

-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath  *)indexPath{ }

so i will change the specific row data in this method,but how can i set the row index?

Answer 1

Have you tried

- (void)reloadRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation

Swift

func reloadRows(at indexPaths: [IndexPath], with animation: UITableView.RowAnimation)

This will allow you to reload a single row.

The reloadData method reloads the whole table
