Multiple UITableview in Single Viewcontroller

Question

I have a viewcontroller in that i want to show 3 tableviews(because the content and the table properties are different). How do i add these delegat

Answer 1

None of the previous worked for me, I come up with the following solution:

  public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
  if((tableView1 != nil) && (tableView  == tableView1)) {
   return Items1.count
  }
  else if((tableView2 != nil) && (tableView  == tableView2)) {
   return Items2.count
  }
  else if((tableView3 != nil) && (tableView  == tableView3)) {
   return Items3.count
  }
  else {
   return 0
  }
}

Answer 2

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;
    }   
}

Answer 3

You can manage multiple tableView in a single ViewController by writing below code inside UItableViewDelegate and UItableViewDatasource.

public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    if tableView  == tableView1
    {
        // place your code here
    }
    else if tableView  == tableView2 {
        // place your code here
    }
    else {
      return 0
    }
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if tableView  == tableView1
    {
        // place your code here
    }
    else if tableView  == tableView2 {
        // place your code here
    } 
    else {
        return 0
    }
}
// You can set a different size of your tableView using below lines of code 
if tableView  == tableView1{
    return 50
}
else{
    return 40
}

Answer 4

//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;
}


}

Answer 5

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];
