I have one large scrollView that contains a collectionView and a tableView. Neither the collection view and table view scroll independently. Both are resized based on their content so the user is just scrolling a long view within the scroll view.
This has always worked out fine until ios 9.1. Now any attempt by the user to pan within one of the collection container views fails to scroll the outer scroll view.
Can someone explain what has changed in ios 9.1 to make this setup no longer work?
My problem was entirely related to this issue with LXReorderableCollectionViewFlowLayout

Im using Storyboard and I have a tableview that fits the entire viewcontroller.
When I run the app I get something like this in the footer of the app.
If you see the storyboard designer, the tableview fits the view.
So if you see there is like a gap between the bottom of the view so the tableview is not filling that gap.
Any clue?
UIScrollview scroll is not working when i tested application in device (iPhone 5), But scroll is working properly in iPhone 5/5s/6/6 Plus simulator. I am developing application using Xcode 6 and UIStoryboard with AutoLayout.
I set the top, bottom, left and right constraints of UIScrollview with relative to Superview. And i also set the constraints of every UIControl which is in the UIScrollview.
Has any one have solution regarding this issue?
Please see below screenshot for reference.
It's probably easiest to have the scroll view contain a single view, which then contains all of your scrollable content. That single view should be anchored to all 4 sides of the scroll view, and if it's only meant to scroll vertically (which is what your screenshot makes it look like), then set the content view to be the same width as the parent of the scroll view.
To make sure an UIScrollView scroll, you have to check
Size
Your content View is bigger than your Scroll View. If you want it to be scrolled vertically, make sure its higher; horizontally, wider.
Constraints
Make sure your Scroll View is pinned to its super view, Top, Bottom, Leading, Trailing.
Make sure your Content view of Scroll View DOES NOT have CenterY constraint set to Scroll View, cause that'd make content view stuck with Scroll View and it'd never be able to scroll. (That happens to me the last time I was stuck)
Interface Builder settings
Make sure the check in Interface Builder under Scroll View is checked:
Scrolling section, Scrolling Enabled.
I have a project I was working on in XCode 4.whatever where the main view is a Netflix-style layout with a series of horizontally-scrolling scrollviews. The main scrollview may be scrolled vertically to see all of the horizontal ones. This is connected to a navigation controller so when an item is touched it performs a segue, whereupon the user can click a standard navigation bar back button.
This was working as expected with XCode 4.*, iOS 6.1. I have now upgraded to XCode 5 and iOS 7. The scrolling works fine upon initial load - the main vertical one and subview uiscrollviews. After navigating to an item and touching the back navigation bar button the main view won't scroll vertically. The subviews that are visible still scroll horizontally.
I am using a storyboard. The master view controller contains a Scroll View as the top item and a View with a couple subviews for the feature section at the top. The horizontal scrollviews are added programmatically.
The master view controller is a UIScrollViewDelegate and I have connected an IBOutlet from the main scrollview to my master view controller .h file.
That it works initially and then stops scrolling leads me to believe that the content size is being recalculated - and set equal to the frame size - after the navigation. However, I tried setting the content size within viewWillAppear to no avail. I did verify the routine was being called after navigation.
Any ideas on why the main scroll view loses its scrolling?
I have a 10.6 app that I am building on Lion with Xcode 4.3
There is a horizontal split view in the main view, containing the following:
The top view contains an NSSearchField with an NSTableView below it.
The bottom view contains a WebView.
I have it working, but when I resize the split view the top view behaves oddly.
What I want to happen is for the search field to remain where it is, the tableview to remain where it is, but to expand if the split view is dragged down. If dragged up, I want the webview to overwrite the search field and table view.
You can see what I mean in this clip: http://dl.dropbox.com/u/160638/Work/TENSOFT/resizemostlyokay.mov
This keeps the things in the right place when I drag up, but doesn't expand the table when I drag down. The view is expanded, but not the table.
So, I changed the autosizing constraint on the table view / scroll view to make it expand when the view is resized. This is what happens: http://dl.dropbox.com/u/160638/Work/TENSOFT/resizeproblem.mov
When the split bar is moved upwards the table view is moved upwards inside the top view until it overwrites the search field. It doesn't move back when the bar is moved back down.
I cannot find a way to make this work by changing the autosizing constraints. This is usually pretty easy stuff, so either I'm missing something obvious or...?
Has anyone seen this behaviour before when creating SL apps on Lion with Xcode 4.3?
FYI, if I replicate this in a new 10.7 project using auto-layout everything works fine.

Darren.
When you allow an NSSplitView to make one of its subviews very small so that the subviews effectively overlap you get layout issues and this is one of the reasons that Apple introduced auto-layout (watch the WWDC video about auto-layout and I think they demo this problem near the beginning).
If I were you I'd set a minimum size for the top pane so that, for example, it stops resizing when it is 100px high. You can then allow it to collapse so that the user can still show just the WebView.
How can I properly edit a a ScrollView that is a child of a View in Xcode 4.
I have a really long ScrollView (over two pages with lots of controls) and XCode does not let me see the entire scrollview when it is embedded in a View xib.
How am I supposed to be able to edit the ScrollView in interface builder?
Looks like you're taking the correct approach (as per this stackoverflow question) you just edit it side-by-side like you have in your screenshot and then nest the scrollview back into the view before running the app.
