Hi there,

WebViewer does not currently have an API to disable pinch zoom, as it is a part of the default UI behaviour.

You could consider exploring creating a custom UI and making the required changes to the touch controls. More information on custom UI can be found here: https://docs.apryse.com/web/guides/advanced-customization

Alternatively, you could consider setting a maximum zoom level to improve your performance:

To investigate the crashing on your IOS device, please provide the following:

  1. IOS version and device

  2. Does this issue occur on other devices?

  3. Does this issue occur on our Viewing sample or only in your environment?

  4. Please provide any steps to reproduce the issue and a video demo or screenshots.

Best regards,
Kevin
