Delphi iOS zoom + panorama at the same time (two fingers do not release the screen at the same time)

Question

I have this code:

case EventInfo.GestureID of igiZoom: begin if (not(TInteractiveGestureFlag.gfEnd in EventInfo.Flags)) then begin if (not(TInteractiveGestureFlag.gfBegin in EventInfo.Flags)) then begin W := LImage.Width + 2 * ((EventInfo.Distance - FMapsLastDistanceZoom) / 3); H := LImage.Height + 2 * ((EventInfo.Distance - FMapsLastDistanceZoom) / 3); if (W < layoutMapsContent.Width) or (H < layoutMapsContent.Height) then begin W := layoutMapsContent.Width; H := layoutMapsContent.Height; end ; LImage.Width := W; LImage.Height := H; end ; FMapsLastDistanceZoom := EventInfo.Distance; end ; end ; igiPan: begin if (not(TInteractiveGestureFlag.gfEnd in EventInfo.Flags)) then begin if (not(TInteractiveGestureFlag.gfBegin in EventInfo.Flags)) then begin LImage.Position.X := LImage.Position.X + (EventInfo.Location.X - FMapsLastPositionPan.X); LImage.Position.Y := LImage.Position.Y + (EventInfo.Location.Y - FMapsLastPositionPan.Y); end ; FMapsLastPositionPan.X := EventInfo.Location.X; FMapsLastPositionPan.Y := EventInfo.Location.Y; end ; end ; igiDoubleTap: begin UpdateMapsPosition; end ; end; 

However, since the zoom uses 2 fingers, panning is sometimes confused if one finger is removed slightly in front of the other (the image moves to the “last” finger that zooms when the image was opened)

Is there any way to solve this?
