Recreate a uitableview section dynamically on a uibutton`s click - ios

Question

I need to recreate a UITableView section on a UIButton click. Here is an example for this.
AND in button click it should be created like this.
But i am not able to implement this .
Please Help.
I am just creating a simple UITableView with a textLabel.
Code For cellForRowAtIndexPath is
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}

Answer 1

Create a integer variable index and property for tableview in .h
#property UITableView *tableView;
Then in -(void)viewDidLoad set index=0;
Now, write a method which is get called when you tap on add button
-(void)newTableView
{
tableView = [UITableView alloc] initWithFrame:CGRectMake(x,y+height*index,width,height)];
//other code related to table
tableView.tag = ++index;
[self.view addSubview:tableView];
}
Use tag in delegate methods
Edit: As you requested to add new section in Table View instead of new table view
You have to first create table view of grouped style
tableView = [UITableView alloc] initWithFrame:(CGRect)frame style:UITableViewStyleGrouped];
Now, When you hit on that add button call a method
-(void)newSection
{
count++;
[tableView reloadData];
}
Then, you have to implement this delegate methods for grouped table view
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return count;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return #"title";
}
- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section {
//same as your previous code
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//same as your previous code
}

Try this:
Just have a property (e.g. numberOfSections)
Set it to 1 in viewDidLoad
In the numberOfSectionsInTableView: return self.numberOfSections;
In the IBAction of your UIButton add this code:
self.numberOfSections++;
[self.tableView beginUpdates];
[self.tableView insertSections:[NSIndexSet indexSetWithIndex:self.numberOfSections-1]
withRowAnimation:UITableViewRowAnimationBottom];
[self.tableView endUpdates];
