Iphone – Scrolling through UIScrollView in Interface Builder for Xcode 4

interface-builderiphoneuiscrollviewxcode4

This seems to me as though it would be a common problem, but I can't seem to find the answer anywhere. This question seems to address the issue, but I can't seem to get the solution to work and I'm not sure it's referring to Xcode 4.

When using Interface Builder in Xcode 4 and working with a UIScrollView, is there a way to scroll the view down in Interface Builder itself to view/add/edit controls that are out of the viewable section of the screen? I've managed to push a couple controls down using the arrow keys, but now I can't see them and therefore can't manipulate them in Interface Builder. Scrolling the view in IB would be first prize, but if there's a way to even select the controls using a drop-down menu or whatever so I can push them back up with the arrow keys, that would at least be something. Thanks.

Set the ViewController's Simulated Size to Freeform and set a very large height. E.g: 1000 and voilà! You can now scroll to see all the stuff and add even more! :)

~~P.S: Remember to set set Fixed when you are finish to avoid problems!~~

UIAlertView is a modal dialog, triggered within code, so it won't be very useful to set it up in Interface Builder. To create an alert, use code similar to the following:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error message" message:@"Error description" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];
[alert release];

UIScrollView is right there within the Interface Builder library. I don't know why you aren't seeing it. Its icon is a blank white view with a grey scroller on its right side. Even by inserting such a view within your interface, you still may need to set some parameters in code to get the scrolling to work just right.

As a conceptual comment, if you want 50 labels within a scroll view, I think you might be better served by using a UITableView instead.

I bet those are used for the scroll indicators to the right and bottom of the view.
