CGPoint contentOffset = [_scrollView contentOffset]; CGPoint validContentOffset = contentOffsetBoundedInValidRange(_scrollView.get(), contentOffset) if (notEqualThingy(contentOffset, validContentOffset) return true; > Source/WebKit2/UIProcess/API/Cocoa/WKWebView.mm:1563 > + BOOL isStableState = !(_isChangingObscuredInsetsInteractively || [_scrollView isDragging] || [_scrollView isDecelerating] || [_scrollView isZooming] || [_scrollView isZoomBouncing] || [_scrollView _isAnimatingZoom] || [_scrollView _isScrollingToTop] || [self _scrollViewIsRubberBanding]); Of course, [isDragging] and [isDecelerating] is not enough, that totally make sense :( |
