AVPageViewDrawRectOutline does not work properly in Acrobat DC

When you implement the code as follows rectangle disappears.

AVPageViewDrawNow(pageView);

～

AVPageViewSetColor ( pageView, &red);

AVPageViewDrawRectOutline ( pageView, &rect, 2, NULL, 0);

AVPageViewSetColor ( pageView, &colorVal);

What there is a way to ensure that does not disappear figure?

can someone give me any advice?

‌You say it does not work in DC. Do you imply that It does work correctly in other releases, or is this the first time to use this code?

We use this code from a previous, Acrobat X was operating.

However, to draw a rectangle in the Acrobat DC but will soon disappear.

‌ok, appears but vanishes. Are you using the AVPageViewDidDraw callback and redrawing as many times as needed?
