Question

I have the answers showns in table view i want that if users selet any of the cell is should get checkmarked image with text side and if mean time he selects another cell from first cell checkmark should be removed and shown on the selected

Answer 1

In .h file create variable

UItableviewCell *selectedCell;

In didSelectRow method remove selection from saved cell and save new cell as selected:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
    if (selectedCell) {
        selectedCell.accessoryType = UITableViewCellAccessoryNone;
    }
    UItableviewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if(cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
    else {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
    selectedCell = cell;
}

To prevent problems with reusable cells u can create NSIndexPath variable instead of UITableViewCell in .h file:

NSIndexPath *selectedCellIndexPath;

and change didSelectRow method:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
    [tableView scrollToRowAtIndexPath:selectedCellIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:NO];
    UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:selectedCellIndexPath];
    selectedCell.accessoryType = UITableViewCellAccessoryNone;
    UItableviewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if(cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
    else {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
    selectedCellIndexPath = indexPath;
}
