UIWebView throwing exception for [WebActionDisablingCALayerDelegate setBeingRemoved:]

Question

When running against iOS 8, I began to see the following exception coming from the deep bowels of UIWebView:

[WebActionDisablingCALayerDelega

Answer 1

Not sure if this is your case, but I also started seeing this problem on iOS 8 and we tracked it down to the usage of the following CSS property on an iframe:

-webkit-overflow-scrolling: touch;

After we removed it, we no longer had those error messages.

Note: in my case, it didn't happen in response to changing any constraints, but rather it happened while we were navigating through the HTML.
