我有些日子有一个我无法理解的问题
我的混合应用程序与Web服务进行通信，该服务返回带有要呈现的html的加密文本。然后应用程序解密此文本并使用html呈现WebView。这个html使用嵌入在app中的css文件
当我通过XCode调试时没有发生什么事情，但是当我从App Store下载相同版本时，应用程序会在加载WebView时崩溃。这种情况只发生在iPhone 6和iPad Mini 3等新设备中。在最古老的设备上工作正常
我在模拟器和iPhone 6中进行调试，出现任何问题
我试过不要使用css本地文件，但问题还在继续
另一个不使用加密html的WebView工作正常。
你知道什么可以吗？
我应该开发本地方式吗？
