-(void)loadView
{   
    // create and configure the view
    CGRect cgRct = CGRectMake(0, 10, 320, 100); //define size and position of view
    myView = [[UIView alloc] initWithFrame:cgRct]; //initilize the view
    myView.autoresizesSubviews = YES; //allow it to tweak size of elements in view
    self.view = myView; //set view property of controller to the newly created view
    UITableView * tableView = [[UITableView alloc] initWithFrame:cgRct style:UITableViewStylePlain];
    tableView.editing = YES;
    tableView.dataSource = self;
    tableView.delegate = self;

    cgRct = CGRectMake(0, 120, 320, 100); //define size and position of view
    UITableView * tableView1 = [[UITableView alloc] initWithFrame:cgRct style:UITableViewStylePlain];
    tableView1.editing = YES;
    tableView1.dataSource = self;
    tableView1.delegate = self;

    cgRct = CGRectMake(0, 230, 320, 100); //define size and position of view
    UITableView * tableView2 = [[UITableView alloc] initWithFrame:cgRct style:UITableViewStylePlain];
    tableView2.editing = YES;
    tableView2.dataSource = self;
    tableView2.delegate = self;

    [self.view addSubview:tableView];
    [self.view addSubview:tableView1];
    [self.view addSubview:tableView2];        
}

It's possible, but in the sense you're describing is probably a UI convention violation. You should be presenting one UITableView per screen, where tapping a row on the first "drills down" into a second UITableView -- like a hierarchy.

Here's a sample code. But the better approach is, yes, to have different delegates/datasources for both tables.

To change table2 contents depending on a table1 selection, you may just use [table2 reloadData] in a

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

You could consider using Section in uiTableview.

This will helps with memory foot print compares to loading in 2 UiTableView.

First set the number of section on load and should a certain condition are met. Set the section to 2, call [tableview reloadData]

This should load the - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView; where you set the number of section to 2.

Within - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section; you will set the numbers of rows in each section using

if (section == 0){ do something} else { do something else}

This is assuming you have 2 sections.

Finally within - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;, you should use the same if else to check which section and load the respective data in.
