Multiple UITableview in Single Viewcontroller

It will be the same as you do it with one table view, but you should check which tableview is currently using.

myTableView1.dataSource = self;...- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {  if (tableView == myTableView1) {    // your code 1  }  else   if (tableView == myTableView2) {      // your code 2  }  else   if (tableView == myTableView3) {      // your code 3  }}

Edit:

About brightness:

How to change brightness in iOS 5 app?

And about UISlider it has minimunValue and maximumValue properties.

- (void) sliderChanged:(UISlider*)sender{    UISlider *slider = (UISlider*)sender;    [[UIScreen mainScreen] setBrightness:slider.value];}

Edit:

slider.tag = 1;[cell addSubview:slider];...// when you need..indexPath = [NSIndexPath indexPathForRow:myRow inSection:mySecion];UISlider* slider = (UISlider*) [[self.tableView cellForRowAtIndexPath:indexPath] viewWithTag:1];

You always get a reference and can always check for which tableView delegate or dataSource method is called.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{    if (tableView == self.tableView1)    {        return 1;    }    if (tableView == self.tableView2)    {        return 1;    }    if (tableView == self.tableView3)    {        return 1;    }}

You don't gain anything by using same identifier for all tables. Use something like:

-(UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath{        if (tableView == self.tableView1)    {        static NSString *CellIdentifier1 = @"cellForTable1";        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];        if (!cell)        {            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1];        }        cell.textLabel.text = [NSString stringWithFormat: @"table1: %d.%d", indexPath.section, indexPath.row];        return cell;    }    if (tableView == self.tableView2)    {        static NSString *CellIdentifier2 = @"cellForTable2";        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];        if (!cell)        {            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2];        }        cell.textLabel.text = [NSString stringWithFormat: @"table2: %d.%d", indexPath.section, indexPath.row];        return cell;    }   if (tableView == self.tableView1)    {        static NSString *CellIdentifier3 = @"cellForTable3";        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier3];        if (!cell)        {            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier3];        }        cell.textLabel.text = [NSString stringWithFormat: @"table3: %d.%d", indexPath.section, indexPath.row];        return cell;    }   }

//add tag in tableView .myTable1.tag = 200;myTable2.tag = 201;myTable3.tag = 202;- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{if (tableView.tag == 200){    return 1;}if (tableView.tag == 201){    return 1;}if (tableView.tag == 202){    return 1;}}
