Hello, I’m AiRon, an automated tech support bot :robot:
While you wait for one of our customer support representatives, I can help you with your question.


It seems like you’re experiencing crashes when zooming in on an iOS device using Apryse’s WebViewer. This issue might be related to memory limitations or rendering processes on iOS. Disabling pinch zoom without affecting swipe page navigation can be a solution to prevent these crashes.

Some things you can try:

  • Disable pinch zoom by setting the zoom property to false in the WebViewer configuration. This can help prevent crashes related to zooming.

  • Ensure that the WebViewer is updated to the latest version to benefit from any bug fixes or performance improvements.

  • Consider optimizing the PDF or reducing its size if memory usage is a concern on the device.

  • Toggle the progressive rendering option to see if it helps with performance.

Hello Prachi,

Thank you for contacting WebViewer Forums.

After some investigation, WebViewer does not currently have an API to disable pinch zoom. As it is a part of the default UI behaviour, you can consider exploring creating a custom UI and making the required changes to the touch controls. More information on custom UI can be found here: Advanced UI Customization | Apryse documentation

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.

Regards,
Luke
