I'm making a pageview that has a bunch of scrollable pages inside it. I have the pageview working, and the viewcontrollers that it rotates each have a scroll view inside them. The problem is, I think, that the scrolling doesn't happen because the touches don't get through to the pageview. The scroll view should only scroll vertically, while the pageview works with the horizontal scrolling. Is it possible to send through only the vertical touches, or is there another way?
Thanks
If you're using a storyboard, open the Attributes inspector of the embedded UIScrollView and deselect the "Shows Horizontal Indicator" option. Do the same on the UIPageViewController, but for the "Shows Vertical Indicator". However, you also have to ensure that the scroll view's contents aren't wider than the scroll view itself; to do this, just constrain the contents' width to be equal to the scroll view's parent.

I want to use an UIScrollView in an UIScrollView. I think it would be clearer with a
picture
The black border is the border of the screen, the purple is the first UIScrollView and the blue is the second UIScrollView. The arrows show the direction of the scroll.
When I try to put the second UIScrollView in the first with a different scrolling direction, the second show the content twice... I made a video
I have created design for you to explain how to add scroll view inside scroll view.
Here see the following image with constraints.
Note: This is static view not dynamic, This is create to clear concept of ScrollView inside ScrollView. If you are planning to make ScrollView with design then you need to do some more study on AutoLayout with ScrollView.
I have a view where content is supposed to scroll over a few elements. One of which is a button. What I did is place the button and all background elements, and then created a scrollview on top of that.
However, the touch events now (obviously) go to the scrollview, and not to the elements in the back. Is it possible to enable interaction through the empty parts of a scroll view?
Screenshot here:
There is a scrollview on top of e.g. the "next" and "edit" buttons. but I'd like these to be clickable anyways.
Thanks.
I'm going to assume that the content you want to scroll is in a subview. ScrollViews always serve as the first layer of any scrollable UI. Put scrollview in your subview then UIView over your ScrollView and over that add your elements.
To elaborate on my question, I've three scrollviews one top of another, let say base, middle and top. Base scroll view's content size is more so it will scroll, middle scrollview's content size is equal to its frame so it will not scroll, top scrollview's content size is more than its frame so it will also scroll.
Now when I scroll the top scrollview, once it reaches its end, I"m expecting it would scroll the base scroll view as middle is not scrollable. But it seems middle scroll view consumes all my scroll events and not letting the scroll event to go to base scroll view.
I"ve tried by setting more content size to middle scrollview, then it working as expected, first top scroll view scrolls fully then it passes the scroll event to middle scroll view then to the base scroll view.
Now it is more evident that middle scrollview (which is non scrollable) is consuming all of my scrolling event from going to base scroll view. How do I prevent that.
Note : As I've to support zooming, I need scroll view in all three levels.
Any help would be really appreciated.
Thanks.
I have a UIScrollView where one of the elements, when touched, pops up another UIScrollView, of the same size (full screen) as the underlying view. I want this top scrollView, when shown, to be the only element responding to touches, but as it is, if the top scrollView runs out of content, the underlying scrollView picks up the touches and scrolls its content. How can I force the responder chain to stop at the top UIScrollView without putting it in a separate UIViewController?
Try setting scrollEnabled to NO on the base scroll view when the "top" scroll view is shown, and re-enable it when you want control to return.
I thought about the possibilities in UI Design for a new app. What I want to do is:
Have three view where the user can paginate horizontally. In each of this view there is a UIScrollView (fills the whole view) where the user can scroll vertically.
How could I manage, that horizontal scroll events are managed by the Pagination and vertical scrolls are managed by the ScrollView?
I'm sorry, maybe this is kind of a "beginner-Question"...
There might be a possibility to send the different touches to different UI-Elements?
Place the 3 scroll views inside a large scroll view.
The 3 vertical scrolling views should have a content size that matches the screen's width - this will stop them scrolling horizontally and the event will pass up to the the parent scroll view to allow horizontal scrolling.
Ensure that the content size of the parent view matches the screen height so that it only scrolls horizontally.
