I have a scroll view whose content changes dynamically. Is there any animation effect that i can give to my scroll view when the content is re-populated. The content are just image views. I am using some filtration process to repopulate my scroll view by the image views.

I have an Imageview covering half of the screen height and a tableview below it. Both are wrapped inside a UIScrollView. I want to scroll the whole view. Means inner scroll of tableview won't work and when I scroll, outer scroll will scroll image view up and then showing cells of tableview. At the end, Imageview will hide behind scroll and tableview content will take entire space. Can anybody tell me how to achieve this. ?
Thanks
I don't think you need the outer scroll view(UIScrollView). Why don't you add only the inner table view and image view to where your outer scrollview is added. The image view can be added either above or below the table view. Let say your image view is below the table view then your image view will be covered by table view. In order to make it fully visible, set the talbview's content inset top to imageview's height and its background to clear color. then you can see both image and table view contents without one covering the other. The last thing you need to do is you have to handle the image view's y position when you scroll the table view so it looks like they are in the same scroll view. Use the scroll view delegate that is already available to you and play with scroll view's content offset and image view's y position.
I answered some similar question here with some sample code. Hand off parent container's pan gesture to nested UICollectionView
It does with collection view but the main idea is same.
when i scroll up the collection view, 3rd view has to decrease the height and move behind the 2nd view with animation, and the 2nd view has to decrease the height and move behind the 1st view with animation. and vice versa has to happen when we scroll down the collection view. for more details look on to the comment section. i have attach the example link.

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 UIView that has a container view hidden off the frame that I reveal via animation when you click a button. However, once the animation completes I cannot interact with any objects in the frame that just animated into view.
View Hierarchy
View layout
You will note two things about the view layout
the Container view is outside of the normal view frame/bounds
it has a fixed height (those are the constraint likes you see)
I tried expanding the frame height and bounds in order to accommodate the height of the container view, but after the animation I still can't interact with views in the Container.
What do I need to modify to allow interactions to work once this view animates into view?
I have a view that contains a scroll view and that scroll view has another 2 views in it: on top a standard view, and under that another view. This last view has a scroll view inside it. (a matroshka doll has nothing on this app) .
The problem is there is a button that causes the bottom view to resize and increase it's height, but the outer scroll view doesn't increase content size. So the bottom part of the bottom view (now resized to be bigger) is not visible.
Any suggestions on how to fix this mess ?
