How to see a longer mainWindow.xib in IB?

Question

In the IB mainWindow.xib, I have a few controls/text/image which I need to put in but the IB can't be scrolled and I don't have enough space to drag-and-drop my controls to the IB. Is there a workaround?
Please advise.
Thanks.

Is there an automatic scrolling of contents (in simulator) without using UIScrollView?
No, there's nothing in the iPhone OS that automatically scrolls the view regardless of how it's constructed. And as the name implies, the Simulator is intended to behave like the actual device. There will be important differences due to fundamental hardware limitations. E.g., you can't expect to accurately test the response to every kind of touch on the Simulator. But to a first approximation, you can expect the Simulator to present the very same UI as the device.
Note that some important classes such as UITableView and UITextView inherit the ability to scroll from UIScrollView. Also, UIWebView can scroll even though its not descended from UIScrollView. But an ordinary content view such as UIView will not scroll automatically.
To build a scrollable content view in IB, add a UIScrollView object to the xib and connect it to the "view" outlet of the controller (e.g., the File's Owner). For the next step it's easiest if you set the View Mode switch in the xib document window (left end of the top tool bar) to the Center position. You should then see a two column table with a tree of small icons to the left. Now drag the View icon onto the Scroll View icon so that the Scroll View row is highlighted in blue. When you drop the View icon its line should be indented to show that it's now a subview of the Scroll View. You may now set the height of the View object to whatever you want in the Size Inspector, and then scroll it manually as described in my first reply.
After buiding the xib, go back to the controller class @implementation and set the contentSize property of the scroll view to the height of the content view. E.g.:
// SecondViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
// set the nav item title for this view
self.title = @"Second View";
[(UIScrollView*)self.view setContentSize:CGSizeMake(320, 1000)];
Since we connected the controller's "view" outlet to the Scroll View in IB, the address of the scroll view is now self.view. If we wanted to add an additional ivar for the content view, we could obtain its size directly instead of hard coding 320, 1000. In fact it's often a good idea to reset the content view frame here, since IB sometimes tries to outsmart us and change the frame size of the content view back to 320, 460 while we're not looking.
