Hello, I’m AiRon, an automated tech support bot While you wait for one of our customer support representatives, I can help you with your question.
It seems like you’re experiencing issues with vertical scrolling in the PDFTron WebViewer specifically on iOS devices using Safari. This could be related to the touch event handling differences between iOS and other operating systems.
Some things you can try:
Ensure that the WebViewer container has the correct CSS styles applied, such as overflow: auto or overflow: scroll.
Verify that touch events are properly handled by the WebViewer. You might need to add touch-action CSS properties like touch-action: pan-y to enable vertical scrolling.
Check if there are any CSS styles or JavaScript libraries in your React application that might interfere with the WebViewer’s default behavior.
Make sure that your WebViewer version is compatible with the iOS version you are testing on, as there can be discrepancies in how different versions handle certain features.
Consider testing on different iOS browsers to see if the issue is isolated to Safari.

Are you able to reproduce this issue on our Showcase?
I noticed in your code that you are using touchstart and touchmove events. Could you try removing these events to see if you can narrow down the issue? Are you able to provide a sample project I can test with?
No its working perfectly fine on the showcase one,
I tried removing the touchstart and touchmove events but its still not working on safari browsers in ipad air mini or other ipads.
Yes I can provide a sample project give me some time, in the meanwhile attaching the code without the events.
