Question

I’ve got UItableview and also two buttons Next and Previous tapping on which I should go to the selection of the previous/next cell? is it possible? Moreover, how to remember the cell the user last tapped so that it is selected on start-up?

Answer 1

Implement UITableViewDelegate and save the currently selected index in didSelectRowAtIndexPath:

NSIndexPath *currentSelection;

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    currentSelection = indexPath;
}

Then in your button action you can do something like…

- (IBAction)didTapNextButton:(id)sender{

    //Remember to check boundaries before just setting an indexpath or your app will crash!
    if(currentSelection){
        currentSelection = [NSIndexPath indexPathForRow:currentSelection.row+1 inSection:currentSelection.section];
    }else{
        currentSelection = [NSIndexPath indexPathForRow:0 inSection:0];
    }

    [self.tableView selectRowAtIndexPath:currentSelection animated:YES scrollPosition: UITableViewScrollPositionTop];

}
