I have been working in storyboard and something strange has happened. When I select an image, instead of the image actually highlighting an area above it is highlighted. This is true of all the elements in the View Controller. They are off vertically.
It's possible that in adding and subtracting elements I did something to the top layout but I can't tell what. All the elements are within a scrollview that, in turn, is within a view and the dimensions for both are set to 0,0,320,1000. I am not using auto layout.
The app still builds and runs normally but this makes it difficult to work on this screen in storyboard.
Here is a screenshot of the image and selection showing above it:
Anyone seen this or can suggest what could be causing it?
I have a swift app I have been working on for some time now. I noticed that my init view controller has extra space at the top and the bottom of the view, so much that it allows me to pull up and down on the first view and let go and have it spring back into where it was. I removed all my constraints thinking I had an issue with them, but it's still done the same thing. The size class is set to any any, and all my graphic fit inside the view, yet I still an able to pull up and down.
I also made sure my view, wasn't a scroll view, it's not.
I looked around for similar issues, but couldn't find anything like this.
Thanks for the help!
Here is what my view looks like in IB
When I run the app.
Showing the amount I am able to pull it down from the top.
If you remove all of your constraints, and the storyboard is set to use auto layout, it usually won't show up correctly, as you have seen. You will have to add the constraints to each element in your view controller. To do that, you can control click on each and drag it where you want to connect a constraint. Or, use the pin and align buttons in the bottom right corner of the storyboard view.
There is a good tutorial from apple that I suggest you read. It will help you with the basics of using auto layout. Another option would be to not use auto layout. To turn it off in the Storyboard, go to the file inspector and uncheck the box "Use Auto Layout".
I'm using ECSlidingViewController. When the app starts, it opens a scroll view which is resized dynamically, since it contains both labels and a table view. Both the table and the scroll view containing it are resized.
Everything works as intended when the view is first loaded. However, if I open and close the menu view, or if I use it to go to any view which resizes itself, the resizing does not work. Instead, it displays the scroll view as if it has the height assigned to it in the storyboard.
I'm completely lost as to why this happens, and would greatly appreciate help. I can post code as well, of course, but I don't know what code might help, since I guess that the error is on ECSlidingViewController's part.
Are you using auto layout? If so, whenever something else happens that triggers the application of the constraints, all the frames will be reset to the values dictated by those constraints. Try turning off auto layout and see if that fixes it. Refer to your auto layout settings.
Alternatively, if you want to keep auto layout, I'd generally suggest changing the frames by programmatically changing the constant values of the constraints. But, I'm not familiar with ECSlidingViewController, so I don't know if that's a reasonable option in this particular case.
I have a problem adapting my apps to the new iphone5 layout, I've made the following passes:
Added a retina 4" splash image
Modified the interface in my storyboard with "Size inspector" to change the anchoring of the widgets
Tested the app with iOS6 "retina 4" simulator.
The app works as expected except when the user pop up the keyboard to edit a text, I use the "stretching scrollview" method for this particular situation and this seems not compatibile with the "autosizing" properties of my widgets, here is an example, from iOS6 simulator, without and with keyboard:
And here is what happens:
I'm quite sure this is a coherent behaviour since my main view is stretched so the other items inside it are stretched following their anchoring, the fact is that I'd like to have the same behaviour of my previous fixed position (all widgets anchored to the top left corner) with the iphone5 gui expansion, is this possibile?
How do you solve the problem of showing a keyboard and scroll hidden content in an iphone 5 compatible way?
I have been having similar problems. From what I have found thus far, we may need to remove all constraints on the view within the scrollable view, because it appears that it's contents are being resized along with the frame of the scrollView. I know that setting the internal view's frame manually in viewWillAppear will work, but then you are stuck having a view that is the same size for both iPhone4 and iPhone5 (albeit it will scroll). Or you could "pin height and pin width" of the internalView right there in storyboard.
Two potential approaches that may work. Sorry I can't confirm these as I'm giving up and redesigning around this problem.
1. Programmatically add constraints to your internal view's subviews. The programmatic constraints will allow you to "spring" the distance between your elements proportionally. When adding constraints programmatically, you are given access to a factor called "multiplier" (not to be confused with priority), which I saw someone else on stackoverflow posting about.
2. You can design the internalView in Interface Builder as a separate viewController with it's .xib file, and then use storyboard to load it as an embedded viewController to a "containerView" object, which you would put in place as the new "internal view" of the scrollView. Perhaps then the .xib would first resize to the correct iOS device, and then you could use its frame to resize the containerView.
My advice is create a small test-case of these before implementing, else you end up like me, having spent hours down the wrong path and facing a dead-end.

Make your life easier by NOT setting the ScrollView as the main view of the ViewController.
--Instead, make ViewController.view a dummy/blank view, and embed a scrollView inside that view. Then, embed another view (my CustomView) in the ScrollView. CustomView contains all the visible controls and text boxes and buttons. There is NO HEIGHT CONSTRAINT on CustomView.
I have a vertically scrolling uiscrollview - imagine an 'about this app' page of a tab bar app which goes on a bit and requires a scrollview. It only contains a few images, a video and some text (only the video has been coded in - the rest have been placed in the GUI). In storyboard (Interface Builder?) Xcode 4.2, everything is set up as it should be and works fine, but the view is only as large as what you see on the screen, is it not possible to manually arrange in storyboard the items that are initially offscreen - that you need to scroll up to? The only way I've found so far is to design them on the visible view then navigate them down with the arrow keys..
In the storyboard select the viewController, then in Attributes inspector change 'size' to 'freeform'. Then change the 'height' of the view/scroll view to as big as you need. The default settings of struts and springs should take care of resizing the view back correctly when the app is run, but you should double check.
I feel your pain. The only way I found is to manually pan the scroll view in the size inspector to reveal the portion of the view that you wish to visually edit.
Use a UIView to contain elements so they are positioned relatively to this view. Add the view as a subview to the scrollview at 0,0.
pan: use the Y coordinate say to -200, then edit the contents.
to place more contents in the hidden part, pan again to reveal new real-estate
when finished, restore the values of the ScrollView's height and X,Y position.
Make sure the scroll view frame rectangle is smaller than the contained view.

I stumbled upon what I think is even simpler way of dealing with UIScrollView directly in storyboard.
No code needed, just storyboard settings. This maybe new in iOS6.1 / Xcode 4.6
No need to disable constraints (i.e. uncheck "Use autolayout" in File Inspector for storyboard file)
No need to add UIScrollView* scrollView; in .h
No need to add self.scrollView.contentSize = ... in overrides of viewWillAppear or viewDidLoad
Here is what I did (important parts highlighted with **): (see code)
Create a new project with storyboard enabled
Drop in a UIScrollView, set class in identity inspector for view controller
In attributes Inspector, change Size under simulated metrics to Freeform**
Select scroll View; In attributes inspector, turn on "scroll enabled" and "background" to "White" (you'll figure out why - if you don't)
Under Size Inspector (with scroll view selected) change the height to 900 for example**
Add buttons, one on top and one at the bottom
Add a default handler for buttonTouchUpInside for both buttons and simply Log sender.
See Code Select the View Controller and scroll view and check inspectors.
Just change the 'Simulated Size' of the view controller to freeform and set a height that is larger than the usual size, you will be able to see all the outlets you need to edit.
On iOS 6.0 you can drag a Container View inside your Scroll View. This will automatically create a new View for your content, outside of the current scene. You can then resize this view as big as needed to fit your content.
I believe you would still have to set the ScrollView content height at runtime, but at least you can design you content view at once without having to scroll up and down on IB.
Just uncheck the "Autoresize subviews" from any view that you're trying to resize and it should keep all your objects from resizing with it.
I've been struggling with this for a while now, and every single thing I've tried has failed.
Specifically, What I am trying to achieve is a freeform sized modal dialog with a scrollable view containing a container for another view. I have had a lot of varied results, including occasionally having it working correctly. Most often I get it looking exactly correct, but with no scrolling.
In finally downloaded Dickey Singh's code, which worked perfectly but had nothing special. (Excellent clean solution BTW). So, I added a container view to it, exactly as I had in my code, and it broke!
After some experimenting, I worked out what is going on. Just bear with me.
1) Using Auto Layout, the size of the scroll view seems to dictate what the scrolling bounds will be. Setting "contentSize" in "USer Defined Runtime Attributes" seems to have no effect on this, and neither does setting "contentSize" or "bounds" in "viewWillDisplay" or "viewDidLoad". Thus if the initial size of the scroll view is 800x800, that will be all the space that can be displayed. For this reason, when I want a scrollable region, I create a container view and then put the scrolling view inside the content.
2) Without Auto Layout, setting "contentSize" in "User Defined Runtime Attributes" works, as does by setting it programmatically in "viewDidLoad". I prefer to use "User Defined Runtime Attributes" because it keeps the size with the layout. This solution allows you to use scrolling view with more flexibility, since it can be any size at design time.
3) Regardless of Auto Layout, if any view within the scrolling region exactly matches EITHER the horizontal or vertical frame bounds, then the scroll view ceases to function as a scroll view. This applies to my own code and to Dickey Singh's code in every possible configuration that I have tried.
I have no idea what is causing (3), but it is clearly a bug.
I hope this helps everybody out there who is struggling to use scroll view. I imagine that some people are using them without any problem, and some (like me) have had noting but problems with them.
Here's my solution to design a ScrollView with a content larger than the screen entirely in Storyboard (well, except for 1 single line of code :-) :

I'm currently developing an app for iOS 7, and I did exactly as #Dickey Singh's answer, but it doesn't work in the beginning.
After checking the storyboard, I found that we also need to add Auto Layout Constraints for the view controller who holds the scrollView.
It seems that such auto layout constraints would be added automatically before Xcode 5, but now we need to do it ourselves.
The way to add constraints: First select the view controller in the storyboard; Enter 'Editor' in the top menu; Select the 'Resolve Auto Layout Issues'; Select the 'Add Missing Constraints In Container'. Done :-)
