从两个不同的视图控制器更新表视图单元

Question

I am new to IOS and i was just working on UITableView . I want to populate data in table view from two different View Controllers. I want to update cell.textLabel.text from View Controller say viewController1 and cell.detailTextLabel.text from another View Controller say viewController2 .

I have a barbutton at the top right of the tableView and clicking on which it navigates to View Controller A. I have a text label in View Controller A and it returns what ever user has entered to tableView. When i click the cell, it navigates to View Controller B. I also have a text label in View Controller B.

Here is my tableView datasource method

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    Names *namesToDisplay = [self.lists objectAtIndex:indexPath.row];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    if (cell == nil) {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    cell.textLabel.text = namesToDisplay.firstName;
    return cell;

}

where Names is a model class of NSObject and lists is an NSArray in tableView .

It works fine if I update cell.textlabel.text and cell.detailtextlable.text from a single View Controller either View Controller1 or View Controller2.

I can get data from viewController2 but where should I have cell.detailTextLabel.text ?

1. coding conventions... http://en.wikipedia.org/wiki/Naming_convention_%28programming%29#Java is a good orientation.

2. It seems like simple parameter handling. You can share the information between the views in the init process.

ie

// your details view (vc2) header
@class Names;

@interface MyDetailsViewController
{
    Names *names;
    // some variable declaration here
}
// maybe some properties...

- (id)initWithObject:(Names *)p_names;
// ...

@end

...

// your details view (vc2) main
- (id)initWithObject:(Names *)p_names
{
    if ((self = [super init]))
    {
        names = p_names; // so you have the data when the tableView is loading
    }
}

...

// your main view (vc1)
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    Names *namesToDisplay = [self.lists objectAtIndex:indexPath.row];
    MyDetailsViewController *viewController2 = [[MyDetailsViewController alloc] initWithObject:namesToDisplay];
    [self.navigationController pushViewController:viewController2 animated:YES];
}

if there are further problems, please give some more information where exactly ;)
