@ChandramaniPatel What framework are you using on top of cordova?
I was using Sencha Touch and as it is out of date some events were not getting fired
I needed to rework quite a bit

@msd117
Same here .
I use Sencha CMD with Coredova.
Please update the thread, if you get any solution.

@ChandramaniPatel

There was no single solution for it
Like I replaced Scrolling(sencha one) with CSS Scrolling
I was having issues with the date field not getting displayed, so I used the Input type date
For some List control(which has a refresh method) I called refresh or setActiveComponent on their parents and stuff

Basically the height and width are not being set on some component inner child elements that causes the issue, refreshing helps if the function is available otherwise we need to look for alternate solutions

Please let me know if you need any more help with examples... I almost wasted 2-3 weeks on this. hope your get resolved soon

WebKit on iOS 18.2 removed support for the non-standard overflow event, which was used by older versions of Sencha Touch to calculate scrollable areas. I'm pretty sure the latest version of Sencha Touch has long-fixed this, because the overflow event was removed from Android WebView several years ago.

@dpogue Unfortunately, there is no Latest version of Sencha Touch

Final release
2.4.2 / June 15, 2015; 9 years ago

Later it merged into Extjs.

Thanks for the information

Can we easily update this in the Sencha Touch library? or that would be too complicated

My understanding is Sencha Touch 2.4.2 works properly. Make sure that you are not overriding SizeMonitor in your application.

No, nothing overridden
and everything works fine in devices with iOS <18.2
