iOS issues with pinching and zooming

I am seeing scrolling issues when pinching and zooming. When zoomed in scrolling from side to side or up and down on a single page is very slow. When I pinch to zoom out to the original size the pdf image studders and twitches.

The same reason as my answer at #55 ,
Maybe not a good algorithm， when have not enough spaces to inertial scrolling, It only can move with your finger, when your finger up, it will stop.
Single page is this case.

Seems like this makes it not usable on iOS then.

I have improved scrolling, please use ver1.3.5 to test it.
