I have a vertically-scrolling scroll view that has a single subview. This subview has a couple of collection views. I want them to scroll horizontally. It doesn't work because they are inside the scroll view.
The problem is that the pan/scrolling gesture is working just for the scroll view and it doesn't propagate to the collection views. I just see the scroll view scrolling.
There is the same problem with tapping on a collection cell. This event just doesn't happen.
I already tried adding the gestures manually but I am not able to scroll the collection views.
How can I propagate all the gestures ?
Thank you !

Im trying to implement a CollectionView inside my viewController.
And it works just fine.
The problem Im having is that the CollectionView scrolls inside the Parent controller.
I wish to make that if you scroll the collection view - the whole view is scrolled and not just the collection view bit.
I tried disabling scrolling on the Collection View but then nothing is scrolling anymore.
So how would I go about setting the collection view, so that once you scroll on it the whole page scrolls and not just the collection view scrolling inside the parent view controller?
It should be simple, and you've done one right thing already.
Disable scrolling of your collectionView (or tableView, in the future just in case you'll use it, they're basically the same).
Add your collectionView (or tableView) inside a scrollView.
That scrollView is of course in your controller's view.
Make sure every constraints are set properly.
You might need to get the size of your collectionView (say height), and set that height value to the constraint height of your collectionView.
These answers of mine in the past should help you:

Voila. The only scrolling enabled is your scrollView that contains your collectionView (or tableView).
I am using UIPageViewController for showing different viewControllers as tabs.
In my child view controllers I have vertical as well as horizontal scrolling content, so I think UIPageViewController is disabling Pan Gesture.
So I am not able to change current view by swiping left or right.
My pageViewController also returns nil for self.pageController.gestureRecognizers
I know that UIPageViewController already has UIPanGesture to change views.
So how can I enable or achieve swipe to change view in my UIPageViewController?
According to screenshot I have tabs at the top and my child view controllers are vertical scrolling and I have few sections with horizontal scrolling content.
Any help would be much appreciable.
Thanks
in my view controller I have a ScrollView for content adaptation on various devices .. I need to insert a tableView inside the ScrollView but I noticed that my tableView not scrolling when it is inside a ScrollView. Can someone help me figure out how to fix this?
If you want your table view to scroll set the content size of scroll view less than that of your table view.
I have a view controller that owns a UISegmentedControl, a UIScrollView, and several UITableViews. The segmented control and the scroll view are subviews of the view controller's root view. The table views are subviews of the scroll view. The scroll view takes up all the space below the segmented control and each table view is as large as the scroll view. Table views are placed horizontally aligned inside the scroll view.
The view controller should support scrolling to one of its table views either by selection in the segmented control (that works) or by swipe gesture (that does not work yet). I have checked that the scroll view's contentSize is appropriate and I have also tried turning the table view cells' userInteractionEnabled off. I have also checked that the table views do not exceed the size of the scroll view as discussed here. (Each table view is as large as the scroll view, albeit at a horizontal offset.) Still the scroll view can|t be swiped horizontally as I would expect.
Could it be that the table views themselves consume all (including horizontal) swipe gestures as part of their support for vertical scrolling? How can I ensure that the scroll view further up in the scroll hierarchy can (also) react to such swipe gestures?
I have a scrollview with multiple views.Enabled horizontal scrolling.Each view contains a tableview.I have page control in scrollview. when i drag horizontally, the views are appearing without tableview except the first view. Please give me suggestions.
Make sure if setContentSize to your scrollview means scrollview content size is the size of your main view.
When you scroll to next view or if you scroll to view displayed for first time, make sure you reload table. You can implement his through delegate and protocols. For example, when you scroll to second view for first time, then controller should call some method on subview to reload its table.
