Subviews in UIScrollViews to page subview by subview instead of scrollview size

[cslew2009]

Hi. I've subviews (UIImageViews) inside a UIScrollView.

I'm trying to enable the subviews to be scrolled one by one. However, if I am to enable paging, the paging will page the by the size of the entire UIScrollView .

Also, if I'm to reduce the size of UIScrollView to fit just one subview and clipToBounds=YES. My gestures can only be detected when the touch is within the boundaries of the UIScrollView, which is not untuitive enough.

So my question is: What can I do to ensure that my scrollview is able to page one subview by one subview? Thank you.

Found the solution.

I wrote a custom UIView class which overrides the hitTest method of UIView.

In the header of the custom UIView class, declare a UIScrollView, later you will need to assign the UIScrollView which is displaying the menu to this variable.

UIScrollView *thatScrollView;

In the implementation, remember to synthesize the variable and overwrite hitTest

   @synthesize thatScrollView;
    
    - (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent *)event
    {
        if ([self pointInside:point withEvent:event]) {
            return thatScrollView;
        }
        return nil;
    }

Then in the UIViewController class, create an instance of the class and assign the scrollview you want to scroll:

  <instance of custom UIView>.underneathButton = scrollView1;
