I am trying to use a UIScrollView to scroll through a few UIViews but it is not scrolling. I've set it all up in interface builder. Can anyone offer any ideas?
You will need to set the content size of your scrollview in your code. Otherwise it doesn't know how far it needs to scroll. See the Apple docs here for more details:

I had a problem using a UIScrollView with xamarin.ios
I used the scrollView normally, and everything is going well, but the point is that I can't adjust the tools size"Constraints" inside the ScrollView, for example I have many sizes for ios phone screens, so I don't want to make a specific width and hight for tools, and that what storyboard force me to do.
any ideas, open source or tutorial.. thank you
AutoLayout on UIScrollView is different from UIView.
Refer to my recent answer Auto Layout within scroll view , also a demonstrative demo in the comment.
I'm still getting familiar with iOS and the use of constraints. Initally had my layout setup with some constraints. But I ran into an issue. When entering text, my text fields are covered by the keyboard. I found some Apple docs: Doc One, Doc Two stating I should use a scrollviewin this case. It sounded easy enough but every time I put the content in the scrollview things go nuts. I've tried adjust my constraints in several ways, but nothing seems to help.
Anyone have any insight on what I'm missing?
Thank you
Before adding the Scrollview
After adding the Scrollview
If you use a UITableView with static cells and make your view controller a subclass of `UITableViewController, you don't need to worry about the keyboard. The table view controller takes care of keeping the focussed text field visible above the keyboard:
I wrote no code for that demo. It's all done in the storyboard. Here's the storyboard outline:
I have a UIScrollView with a rather large amount of controls in it (like a long form or questionnaire).
The controls are static and can be added in IB, but the scroll view itself is not large enough for all the controls (scrolling is necessary, duh!), meaning that I can't see most of my controls in IB and have to align them "blindly".
Is there a way to simulate a scroll offset for a UIScrollView in IB?
You don't need to, just size your UIScrollView to the size that is needed (it will come off the bottom on the phone screen layout in Xcode) and place the items on it
You should check out this link, it gives a great explanation on different ways to implement the UIScrollView.
UIScrollView implementation
Im trying to create a secondary view to my main view. This subview needs to be of small height and it needs to fit another big UIView with a label in it.
Problem is that when I'm using UIView addSubview, the third UIView will be shown out of bounds of secondary UIView.
For ease of understanding my situation, I have created those Subviews using Interface builder with the photo and the result on simulator with the photo.
Any help would be much appreciated.
Thanks

You need to activate the clip to bounds property of some of those views.
fooView.clipsToBounds=YES;
That should solve your problem. Just set the appropriate views to clip to their bounds.
I'm making an App for iPad.
But I faced some troubles because of Touch Event of ScrollView.
I have tried with iphone sample code [link], but I can't get what I want through this sample.
The reason is that my app is only for iPad.
I add my sketchy pic.

I add UIScrollView on ViewController, and add UIViews on this UIScrollView.
UIViews on this UIScrollView must be hidden outside of UIScrollView. But can't be hidden. #.#
And I can't use touch event on UIScrollView - left and right.
What I want is how to use touch event on scroll view.
I searched about this in Stack Overflow and google.
I could find many articles, but unfortunately I can't understand clearly.
Please explain me more easily. I'm a beginner programmer.
make your scrollview to clip subviews by it's bounds:
scrollView.clipToBounds = YES;
this will resolve your "un-hidden views" issue
