UIScrollView within UIScrollView


UIScrollView within UIScrollView

I wish this help you If you set your UIScrollViews to only be scrollable in one axis or the other (ie, set their contentSize property appropriately for this. To have a view only be scrollable vertically, set its contentSize.width value to be the same as its bounds.size.width). then they should just work, assuming that no two views scroll in the same axis. Usually, you'll have the 'child' views scroll vertically, and the parent view scroll horizontally.

Hope this helps UIScrollView has a property called scrollEnabled, which you can set to NO to disable scrolling in your parent scroll view.
I haven't tried it yet, but you may just find that it Does The Right Thing, i.e., the inner scroll view scrolls until it can't scroll any more, at which point the outer scroll view scrolls.

it fixes the issue What you basically need is to subclass the UIView that should intercept touches outside it's frame and override it's hit test method.

help you fix your problem I think what's happening here is that the grey button's highlighted state is being set when its action fires, then unset when the resulting alert or sheet is shown.
(If you're not showing an alert or a sheet, you'll just have to arrange for it to be unhighlighted on the next run loop.)

help you fix your problem I have a UIScrollView with an UIImageView inside. The main goal is to move the UIImageView inside de UIScrollView like drag, zoom, etc. , to rmaddy for you help.
Here is the solution:
code :
//FYI: focusPoint.scale is the zoomScale of the UIScrollView.
let originVisible = scrollView.contentOffset
let convertedPoint = scrollView.convert(originVisible, to: imageView).scaledBy(scale: focusPoint.scale)
let imageViewPoint = CGPoint(x: convertedPoint.x + scrollView.center.x,
                             y: convertedPoint.y + scrollView.center.y)

extension CGPoint {
    func scaledBy(scale: CGFloat) -> CGPoint {
        return CGPoint(x: x * scale, y: y * scale)
    }
}
