将触摸从UIView传递到其下方的UIScrollView

Question

I have a UIScrollView stretching over the entire screen, which the user is able to scroll vertically only. Right 'above' it is a UIView with a few buttons, which covers the bottom 120 px only. The user may tap the buttons to invoke their selectors. But I wish to be able to pass the panning movement to the scrollView, so that the user may scroll the scrollView if they pan with a velocity greater than a certain threshold, if the panning begins over the UIView .

How would I go about it?

Thanks

You can do 2 things.

1. Add a UITouchesMoved function to your uiView, calculate finger movement and move your scrollView accordingly by scrolling it to a CGPoint .

2. You can use UIPanGestureRecognizer.
