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:

[WebActionDisablingCALayerDelegate setBeingRemoved:]: unrecognized selector sent to instance 0x167ee900

* WebKit discarded an uncaught exception in the webView:willRemoveScrollingLayer:withContentsLayer:forNode: delegate: -[WebActionDisablingCALayerDelegate setBeingRemoved:

This is happening when I change some constraints on my UIWebView and then call:

 self.webViewWidthConstraints.constant = newWidth;  [self.webView setNeedsLayout];  [self.webView layoutIfNeeded]; 

(This is so that the webview's content is re-rendered to fit its width correctly).

Luckily the exception is discarded, so the app isn't crashing. Why is this happening, and is there any way to prevent it?

Answer 1

I found that by adding "-webkit-transform: translateZ(0px);" to the scrollable content (I have a div inside my scrollable container), it fixed the issue for me. Hope this helps.
