  • In my case it was triggered by trying to display a UIWebView that had been created from an NSData object with invalid data, possibly from an empty file

  • 测试: 加载本地0KBPDF文件并不会导致CALayerInvalidGeometry

解决

  • WKWebView 或者 UIWebview 初始化 一定要设置 frame

  • 设置Xcode CG_NUMERICS_SHOW_BACKTRACE环境变量 检测异常参数

  • 键盘的问题??
