    NSURLRequest *requestThree=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://xyzt.com?key=init"]];
    responseDataThree=[[NSMutableData alloc]init];
    urlConnectionThree=[[NSURLConnection alloc]initWithRequest:requestThree delegate:self];

You can access both TableView... by put condition like if(tableView == FirstTableView){....}else{....} — iPatel, Jan 30 '14 at 05:16
In tableview delegate methods check the `tableView` is `tableViewTwo` or `tableViewThree`. And you can use different custom cells in `cellForRowAtIndexPath:` by the above check — Akhilrajtr, Jan 30 '14 at 05:20
in interface builder you linked your IBOutlets from File's Owner when you should link them from the cell view. This might be the cause for getting the errors. — Kumar KL, Jan 30 '14 at 05:29
@iPatel i want to shows data on both the tableView at same time so how would program knows data will shows on which tableView. if / else conditions works but how program knows which value is present in tableView currently for checking in if / else statement. — user3171903, Jan 30 '14 at 05:30

Try this.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
 {
return 40.0;
 }

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
 if (tableView == tableViewFirst)
    return arrfirst.count;

else if(tableView==tableViewSecond)
    return arrsecond.count;

return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    if (tableView == tableViewfirst)
    {
       // First tableViewcell
       return cell;
     }
    else if (tableView == tableViewsecond)
    {
        //Second tableViewCell
      return cell;

    }
return nil;
}

i'm doing the same this but how the program knows the current value of tableView for matching the conditions in the if/else statement. both tableView are on the same view....How? – user3171903 Jan 30 '14 at 06:23
In cellForIndexpath your checking if tableView is first or second and if its first then first part will get executed and for second second part will. same as you are checking in all delegates. so the programme will understand which code should run. – Himanshu Jan 30 '14 at 06:53

No matter how much table view you have in a single viewController. As you said you have two tableView tableViewTwo & tableViewThree. So you have to create two array for two datasource. Then set the delegate of both table view.

[tableViewTwo setDelegate:self];
[tableViewThree setDelegate:self];

Now when you reload your table views

[tableViewTwo reloadData];
[tableViewThree reloadData];

for both table view the same delegate will called one after another. As you already put the condition on

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

do the same thing for all the delegate method you have implemented and you want to make differ for different table view. One thing I want to include use ([tableView isEqual:self.tableViewTwo]) instead (tableView == self.tableViewTwo)

refer to this link http://stackoverflow.com/questions/14036604/objective-c-nsobject-isequal-vs-comparison — Tapas Pal, Jan 30 '14 at 06:58
No, in this case `==` is exactly what you want to do. You want to test for *which instance* of the table view the delegate/datasource is referring to. This is not a general test for equality. — trojanfoe, Jan 30 '14 at 07:53

i think this is helpful you for understand @Tapas Pal said set delegates for both tableview

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
          NSString *customCell;
          UITableViewCell *customTabelCell;

            if(tableView == self.tableViewTwo){
              customCell=@"CustomerListCellTwo";
              customTabelCell=CustomerListTabelCellTwo;
            }else{
              customCell=@"CustomerListCellThree";
              customTabelCell=CustomerListTabelCellThree;
            }


        static NSString *simpleTableIdentifier = customCell;

        customTabelCell *cell = (customTabelCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
        if (cell == nil)
        {

            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:customCell owner:self options:nil];
            cell = [nib objectAtIndex:0];

        }


        return cell;
    }
