Add a bunch of controls dynamically to screen in iOS

I am working on a screen where user selects an option from drop-down. Based on this selection he adds a bunch of controls to screen. My drop-down is at the bottom-right corner of the screen. It takes up 20-25% of screen space at the bottom. In the remaining 75% screen at the bottom i need to add 9 labels,6 UItext fields ,2 drop-downs and 2 buttons. I am attaching a markup here.

My question is: in ASP.NET, I have a repeater which has all the above controls. In one of the buttons named "Add More". If I click that button, it adds the same repeater at the bottom of the current one. Do we have anything like that in iOS? Like a repeater which has a bunch of controls and click add and that exact repeater is added at the bottom and so-on and so forth. If any ideas/new ideas based on my explanation pop-up then please let me know. Thanks.

The link http://dl.dropbox.com/u/40597849/mockup2.png

So, the big rectangle to the right containing 8 labels, textboxes, drop-downs and the 2 buttons below it(one is named as "Add More") should be added again when user clicks on Add More. Please ask me if you need more information. 

ITMCustomView *cView = [[ITMCustomView alloc] initWithFrame:frame];
cView.delegate =self;
CGPoint scrollPoint = CGPointMake(0.0, (frame.origin.y/400)*400);
[self.scrollView setContentOffset:scrollPoint animated:YES];
[self.scrollView addSubview:cView];

Initially the very first custom view i add, i add it with this frame size (187, 585, 350, 21); . Next whenever i hit add more i call this delegate

[self.delegate addNewSize:CGRectMake(187,self.y+ 400 , 400, 400)];

This calls the above 5 lines of code and makes a new custom view and adds it to scroll view. I store the self.y as the y value of whatever frame currently being built. So how do i make my scroll view move up and down freely. The screen shows the custom view as they are added but doesnt allow me to go up anymore. I wanted to suppose add the custom view 5 times and i added 4 i just want to scroll up , see i added 4 scroll down and just add 1 more custom view and do other processing with it. But my scroll view is non-functional and its stuck at the just added custom view disabling me to scroll up. If you need more information, please ask me. Thanks.

Use a custom view that contains all your views.

1.) Make a custom class myView which subclasses UIView.
2.) Add all the controls you need in that view class.
3.) include myView in your main view.
4.) initiate as many myView as you like and add them to your main view.

I hope that is clear enough to get you going.

Update: As to elaborate more on the comment bgoers made.
When you create a new class myView sub-classing UIView you get an empty sheet. This sheet will have the frame that you specify either in the class or when you initiate (up to you). Within that frame (myView.h and myView.m in initWithFrame), you can add subViews like buttons or labels. Those subviews will placed relative to the sheet myView.

For example, your draw up is a custom view with all the controls. I can have another one looking exactly like it by simply initiating another custom view without adding more subviews. All I need to do is move the second custom view to where I would like, all the subviews will follow.

I encourage you to read up on how to subclass and how that works in iOS. It is very simple once you get the hang of it.
