I have implemented a UIScrollView, which has a content view. Content view contains the UILables to display texts. Eventhough i have the necessary vertical scrollview for long paragrpahs, there is an unnecessary horizontal scrollview as well.
In this case, position the control view horizontally center in container. This should prevent the horizontal scroll.

I have UI textview inside UIscrollView, so UIscrollview scrolls horizontally and vertically at the same time. is there any way to disable scrolling in horizontal way and enable scrolling to the vertical way ?
thank you
If your scrollView scrolls horizontally, that's means that your textView or another subview is wider than the scrollView's frame.
I have a horizontal scrollview that fills 1/3rd of the view.
I want to put a UILabel in the centre of the scroll view, which I have successfully done with:
let reagentsLocationx = mainscrollview.frame.width/2-100
However, I am struggling to centre the label vertically within the scrollview. When I use similar code for reagentsLocationy it centres the label in the view and not within the scroll view.
How do I centre the label, in Swift, just within the scrollview?
Many thanks.
I think this is because you are using frame and not bounds. I don't believe frame will ever be larger than your screen space, but bounds it equal to the view's actual size. Try basing it on the bounds of the scroll views height.
UIScrollView().contentSize.height might be what you are looking for.
No need of setting sizes in code.
Everything done in the storyboard.
Drag your scrollview into your view controller.
Set top, bottom, leading and trailing constraints from the scrollview to the parent view or safe area.
Drag your text label into the scrollview.
Set your top, bottom, leading and trailing constraints to the scrollview.
IMPORTANT set a second leading and trailing constraint, now from the text label to the parent view (UIView - not scrollview) or safe area.
This makes sure that the text label knows his width and so the scrollview knows it too.
I have two UIScrollViews, one is horizental, the other is like page on the horizontal view. I want to click the status bar and have the vertical scrollView scroll to the top, but it doesn't work.
I searched for some information that said I must set UIScrollView.scrollsToTop=NO, but it doesn't work. Could somebody tell me why?
The scroll view only scrolls to the top if there is a single scroll view present with the scrollsToTop property set to YES.
Make sure it's set to NO on your horizontal scroll view and all the child, vertical scroll views contained within. Then, using the horizontal scroll view's delegate, as one vertical scroll view leaves the visible area, toggle the property to NO and toggle the incoming vertical scroll view's property to YES.
I have two horizontal paging scroll views where a one is smaller and a subview of the the other. Is there a setup that consistently allows a horizontal drag to move the outer scroll view when there is no more paging to do in the inner scroll view?
Apparently you have to turn off the rubberbanding in the inner scroll view for this to work properly.
I'm working on a iphone game, and part of it includes a section where you scroll horizontally through a list of images (which have transparent backgrounds).
but I also want to be able to vertically scroll and change the background image, without the image in the horizontal scroll view changing.
I have the horizontal scrollview working now, and I've placed a second scrollview behind it for the vertical scrollview, but obviously the vertical scrollview doesn't catch the up/down swipes.
Is there some way to push vertical swipes through to the second scrollview, but catch the horizontal swipes on the first?

IF you implement the scrollViewDidScroll Delegate for the first scroll view and catch the scroll offset, you can pass the same to the second scroll and control how the offset moves on the second scroll.
