And when user click on again then i want to show that selected row when view open. How do that? For example when user click on button then open table view and suppose select 50 th row. Now user click on button again then i want to show 50th row directly instead user go to scrolling table view. So tell me how do that? Thanks in advance..

Answer 1

公正的呼吁

- (void)selectRowAtIndexPath:(NSIndexPath *)indexPath animated:(BOOL)animated scrollPosition:(UITableViewScrollPosition)scrollPosition

您的意见。

例如,以下法典将在第一部分选择第50行:

UITableView *tableView;
[tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:50 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionTop];

Answer 2

使用

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:selectedRow
                                            inSection:sectionOfSelectedRow];
[tableView scrollToRowAtIndexPath:indexPath animated:YES];
