Question

I’m brand new to Xcode and Objective-C, and fairly new to programming in general so please correct me if I have a severe misunderstanding.

Here’s what I’d like to accomplish:

• Create a Table View (empty upon startup)

• Have user add and name cells via a Bar Button (pushes to a different view with a name Text Field and “Create” button I’m assuming)

• Each created cell pushes to a new Table View with similar add/naming functionality

• Then each of those cells push to a Text View

It seems to me that the best way to accomplish the first part is by populating a string array, then assigning those elements to the corresponding cells. That’s where I get stuck.

• How do I populate a Table View with an array?

• Should I create a new secondary Table View for every cell, or just populate the same one differently depending on which parent cell is selected?

• And same question as previous for the Text Views at the end of the chain…multiple Text Views or just different text passed each time?

If you got this far, I sincerely thank you and please let me know if I need to clarify anything.

I hope you know how to create a table view.
Now you should create a NSMutableArray to save your strings.

@property (retain) NSMutableArray *stringsArray = _stringsArray;

so your viewDidLoad will look like this.

- (void)viewDidLoad
{
    [super viewDidLoad];
    UITableView *myTableView    =   [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStyleGrouped];
    myTableView.dataSource      =   self;
    myTableView.delegate        =   self;
    [self.view addSubview:myTableView];
    [myTableView release];

    self.stringsArray = [NSMutableArray array];
}

Now the table view delegates

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return [self.stringsArray count];
}

- (UITableViewCell *)tableView:(UITableView *)tmpTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier         =   @"MainCell";
    UITableViewCell *cell               =   [tmpTableView dequeueReusableCellWithIdentifier:CellIdentifier];   
    if (nil == cell) {
        cell    =   [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    cell.textLabel.text = [self.stringsArray objectAtIndex:indexPath.row];

    return cell;
}

Now when you click on your barbutton to add new user, you must add it to strings array and just call [tableview reloadData];

I didn’t understand why you want a text view.

Hope this helps!
