No, zooming can wait for the move to be finished — but I'd like a swipe to start scrolling the inner ScrollView even if the outer ScrollView is still decelerating. >> Additional questions: How does the magic of nested UIScrollView actually >> works ?

That's actually why I wanted to ask about hitTest: I don't want to override too much of the UIScrollView internal logic, which seems already complicated enough :) > Can you add an image of what you expect to achieve to your zip? Sure. At the end, all I care is achieving a behavior somehow like this : http://winosx.com/hosted_files/Slide-diagram.pdf As you can see, the reason I nested UIScrollViews to form groups in the first place is that I want : * The UIScrollView Paging behavior (snapping at bounds) * Individual pages centered on the screen * Pages in the same group be right next of each other * A margin (corresponding to the gap created by framing the page in the view) between each group This, as far as I understand, disable the possibility to stick all pages in a single UIScrollView *and still have a Paging behavior* — because from 1 to 2, the page distance would be [pageWidth], but then from page 2 to 3 it would be [pageWidth + margin]. Or is there a possibility to dynamically adjust the bounds of a single UIScrollView to Paginate to different distances ? (In this case, I could manage the "zooming both pages together" by playing with [viewForZooming]. Zooming is not the big issue there — but Paging is)._______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
