iOS中 遇到的关于Webview加载H5的问题

项目中用Webview加载H5页面，遇到的一个问题.

WebKit discarded an uncaught exception in the webView:willRemoveScrollingLayer:withContentsLayer:forNode: delegate:-[WebActionDisablingCALayerDelegate willBeRemoved]: unrecognized selector sent to instance 0x61800001a5e0

去网上，总结大家的反馈，有这些情况导致了：

********[WebActionDisablingCALayerDelegate willBeRemoved]异常    原因是touch和鼠标事件冲突。

******** This is happening when I change some constraints on myUIWebViewand then call:

self.webViewWidthConstraints.constant=newWidth;

[self.webView setNeedsLayout];

[self.webView layoutIfNeeded];

********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.

********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:

********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.

解决方案：

********为 WebActionDisablingCALayerDelegate 这个私有类添加方法，在后面的一次提交审核过程中，ipa文件提交失败：引用私有API（还是私有类，记不得了）。所以建议不要采用。链接

********使用WKWebview代替UIWebview
