contentScrollViewForEdge method
Pass only a single edge (e.g., NSDirectionalRectEdgeTop) in the edge
parameter. Raises an exception when passed an aggregate edge (e.g., NSDirectionalRectEdgeAll)
Implementation
UIScrollView? contentScrollViewForEdge(NSDirectionalRectEdge edge) {
objc.checkOsVersionInternal('UIViewController.contentScrollViewForEdge:', iOS: (false, (15, 0, 0)));
final _ret = _objc_msgSend_kh1gvt(this.ref.pointer, _sel_contentScrollViewForEdge_, edge.value);
return _ret.address == 0 ? null : UIScrollView.castFromPointer(_ret, retain: true, release: true);
}
