Adding Data/Rows to UITableView (Multiple Tables on one view)

You need to set UITableViewDelegate and UITableViewDataSource for all your tables to a class that will implement the following methods:

For UITableViewDataSource:

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

and

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

As these methods are passed the calling tableview, it should be easy for you to return the correct data for the tableview in question (which you are already storing in an NSMutableArray). You still need to cater for displaying different content for your arrays, but I trust you will manage to do so. NSIndexPath basically tells you which part of your array should be displayed. Assuming, for now, that you are working in an ungrouped table, you would simple create a new cell and fill it with the contents of your array, which is determined by the indexPath:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
    static NSString *CellIdentifier = @"MyNiceIdentifier";
    cell = [aTableView dequeueReusableCellWithIdentifier:NavigationCellIdentifier];

    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        cell.tag = 500;
    }

    cell.textLabel = [myArray objectAtIndex:indexPath.row];
}

In the other data source method, you simple return the count for that array:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if(tableView == myFirstTableView) {
        return [myFirstArray count];
    }
}

The method of UITableViewDelegate you will likely use most often is this:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

which you use to return the desired height for a cell at a given indexPath.

Setting dataSource and delegate is as simply as doing:

myTableView.delegate = ...
myTableView.dataSource = ...
