Group UITableView for Selection

I h开发者_开发知识库ave a UITableView in Group Style, and I am using it with Navigation Controller. When a user click on the cell I am pushing to another view for a user to make selection, while all that is working fine. I want the user to be brought back to the first view when the user makes a selection. and I want to display their selection on the cell.

Thanks in advance for your help

I think you can use the NSUserDefaults.

// view controller to make selection
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *selected;
    if (indexPath.row == 0) {
        selected = @"Apple";
    } else if (indexPath.row == 1) {
        selected = @"Microsoft";
    }

    [[NSUserDefaults standardUserDefaults] setObject:selected forKey:@"SELECTED"];
    [self.navigationController popViewControllerAnimated:YES];
}

Important point is you need to call [self.tableView reloadData] in viewDidAppear.

// view controller to show what a user selected
- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    [self.tableView reloadData];
}

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
    }

    // Configure the cell.
    cell.textLabel.text = @"Choice";
    cell.detailTextLabel.text = [[NSUserDefaults standardUserDefaults] objectForKey:@"SELECTED"];

    return cell;
}
