coordinateSpace property
UICoordinateSpace
get
coordinateSpace
The coordinate space of the focus items contained in this container. The focus items returned by focusItemsInRect: should report their frames in this coordinate space. If you are implementing this protocol, you may find it convenient to return the UIScreen as your coordinate space, and ensure that your contained items report their frames in screen space. Similarly, you might find that your focus items' containing UIView or UIWindow is the most convenient coordinate space to use. You may also choose to implement your own object that conforms to UICoordinateSpace, if that is the most natural solution for your architecture.
Implementation
UICoordinateSpace get coordinateSpace {
objc.checkOsVersionInternal('UIScrollView.coordinateSpace', iOS: (false, (12, 0, 0)));
final _ret = _objc_msgSend_151sglz(this.ref.pointer, _sel_coordinateSpace);
return UICoordinateSpace.castFromPointer(_ret, retain: true, release: true);
