Manually call didSelectRowatIndexPath


You need to pass a valid argument, if you haven't declared indexPath in the calling scope then you'll get that error. Try:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:ROW_YOU_WANT_TO_SELECT inSection:SECTION_YOU_WANT_TO_SELECT][self tableView:playListTbl didSelectRowAtIndexPath:indexPath];

Where ROW_YOU_WANT... are to be replaced with the row and section you wish to select.

However, you really shouldn't ever call this directly. Extract the work being done inside tableView:didSelectRowAtIndexPath: into separate methods and call those directly.

To address the updated question, you need to use the indexPathsForSelectedRows method on UITableView. Imagine you were populating the table cell text from an array of arrays of strings, something like this:

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath    {        UITableViewCell *cell = [tv dequeue...];        NSArray *rowsForSection = self.sectionsArray[indexPath.section];        NSString *textForRow = rowsForSection[indexPath.row];        cell.textLabel.text = textForRow;        return cell;    }

Then, to get all the selected text, you'd want to do something like:

NSArray *selectedIndexPaths = [self.tableView indexPathsForSelectedRows];NSMutableArray *selectedTexts = [NSMutableArray array];for (NSIndexPath *indexPath in selectedIndexPaths) {    NSArray *section = self.sectionsArray[indexPath.section];    NSString *text = section[indexPath.row];    [selectedTexts addObject:text];}

selectedTexts would at that point contain all selected information. Hopefully that example makes sense.


Swift 3.0 Solution

Manually call didSelectRowAtIndexPath

let indexPath = IndexPath(row: 7, section: 0)tblView.selectRow(at: indexPath, animated: true)tblView.delegate?.tableView!(tblView, didSelectRowAt: indexPath)


Just to update @Sourabh's answer, note that you can also provide a scrollPosition when calling selectRow:

let indexPath = IndexPath(row: 7, section: 0)tblView.selectRow(at: indexPath, animated: true)tblView.delegate?.tableView!(tblView, didSelectRowAt: indexPath)

Becomes:

let indexPath = IndexPath(row: 7, section: 0)tblView.selectRow(at: indexPath, animated: true, scrollPosition: .top) // <--tblView.delegate?.tableView!(tblView, didSelectRowAt: indexPath)

The possible constants are:

.none

The table view scrolls the row of interest to be fully visible with a minimum of movement. If the row is already fully visible, no scrolling occurs. For example, if the row is above the visible area, the behavior is identical to that specified by top. This is the default.

.top

The table view scrolls the row of interest to the top of the visible table view.

.middle

The table view scrolls the row of interest to the middle of the visible table view.

.bottom

The table view scrolls the row of interest to the bottom of the visible table view.
