Question

I am trying to implement UITableview based application. In my tableView their is 10 Section and each section having one row.
I want implement each section have Different type of ContentView(1-8 same ContentView 9th section Different ContentView). I did this code For that.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 10;
}

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

    return 1;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier1 = @"Cell1";
    static NSString *CellIdentifier2 = @"Cell2";
    UITextField *textField;
    UITextView *textView;
    NSUInteger section=[indexPath section];
    if(section == 9){
        UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];
        //UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
        if(cell==nil){
            cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1]autorelease];
            textView=[[UITextView alloc]initWithFrame:CGRectMake(5, 5, 290, 110)];
            [textView setBackgroundColor:[UIColor scrollViewTexturedBackgroundColor
                                          ]];
            [textView setTag:([indexPath section]+100)];
            [cell.contentView addSubview:textView];
        }else{
            textView=(UITextView*)[cell.contentView viewWithTag:([indexPath section]+100)];
        }
        return cell;
    }else {
        UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];
       // UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
        if(cell==nil){
            cell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2]autorelease];
            textField=[[UITextField alloc]initWithFrame:CGRectMake(5, 5, 290, 50)];
            [textField setBackgroundColor:[UIColor scrollViewTexturedBackgroundColor]];
            [textField setTag:([indexPath section]+100)];
            [cell.contentView addSubview:textField];
        }else{
            textField=(UITextField*)[cell.contentView viewWithTag:([indexPath section]+100)];

        }

        return cell;
    }  


    return nil;

}

My problem are:
1. After type some thing in the UITextField/UITextView i am scrolling in the UITableView. that time all data in the UITableViewCell(UITextField/UITextView) was lose, except last cell data.
2. If i create cell

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

Instead of

 UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];

Data will repeating . How can i over come this problem?

This line:

UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];

Should never appear in your data source cellForRowAtIndexPath method.

Apart from that, your code is OK, except that you are not setting the text field value anywhere. You need a model (such as an array of strings for the 10 textfield values). This model should be updated when the textfields are edited, and in your method above you copy the value back out of the model and into the textfield’s text property:

textfield.text = [self.modelArray objectAtIndex:indexPath.section];
