Zoom on ios

Webix JS
#1

Is it the desired behavior that on https://webix.com/demos/touch/ I can zoom(with pinch) the whole application? (iPhone)

Hello,
Thanks for the report - it’s an HTML coding problem.
In real applications, it is worth using fullScreen for correct operation.

Thank you! I checked with the following code, but unfortunately it still doesn’t work. (I can still zoom on the IOS devices…)

I can confirm the issue, there is a problem in the test environment.
Could you test locally? It’ll work.

No. It’s not working locally either.

@lBeJIuk,
Could you please specify the iPhone model and iOS version?

Hello @lBeJIuk ,
We have run additional tests. And, as a matter of fact, this behavior has appeared since iOS 10 in mobile safari.
As a workaround you can stop pinch-to-zoom with something like this:

document.addEventListener('touchmove', function (event) {
    if (event.scale !== 1) { 
    event.preventDefault(); 
  }
}, { passive: false });
