How to add UIScrollView to Interface builder?

Question

I have all my controls laid out in interface builder (many labels, buttons etc). How do I put them all in a scroll view in interface builder so that I can have more space and be able to scroll up and down to reveal more controls? Do I have to do this programatically?

Answer 1

Select all the objects you want to put into a scroll view and go to the Layout menu, choose "Embed Objects In" and choose "Scroll View".

Answer 2

Open the view that has all the controls and labels, etc. (in Interface Builder). Select All. Then under the Layout menu, select Embed Objects In... (scroll view).

Answer 3

My preferred solution, where you don't need to hard-code the size of the contentSize:

1. Move all controls into a single UIView (in IB: select all, then go Layout > Embed Objects In ... > View)

2. Hookup that single UIView to your source code using an IBOutlet property (see below)

3. IN SOURCE CODE, NOT INTERFACE BUILDER (IB is broken here, it has bugs where it sets the origin of the UIScrollView incorrectly - it tries to center the view. Apple never bothered to check it for basic bugs, sigh): Move the single UIView into a UIScrollView (see code below).

4. Use sizeThatFits to "automatically" set the correct size.

Code (StackOverflow won't let me put code inside a numbered list. Sigh)

Header file:

/** outlet that you hook up to the view created in step 1 */
@property(nonatomic, retain) IBOutlet UIView *masterView;

Class file:

/** inside your viewDidLoad method */
[scrollview addSubview: masterView]; // step 3
scrollView.contentSize = [masterView sizeThatFits:CGSizeZero]; // step 4

...although I haven't checked this recently, IIRC it works on both 2.x and 3.x

Answer 4

Its easy:

First add a scrollview to your view. Change the size of the scrollview (e.g. make it 700 pixels long). Start putting your controls When you want to put/edit controls in the lower (invisble) part, select the scrollview and change the Y-start position to -300. Voila. After editing set the Y-start position back to 0 or whatever it was.

Wow. I am prototyping an iPad app that's basically a 5 page form with 100s of controls. UIScrollView would work fine for the app, except there is no way I'm going to try to develop like that in IB. That would be a nightmare. I'm really surprised there isn't some better solution for creating UIScrollViews in IB.
