The crash happens in the file WebViewJavascriptBridge.m
in line 95
in the method [WebViewJavascriptBridge _sendData:responseCallback:handlerName:]
.
That line causes an exception in [__NSPlaceholderDictionary initWithObjects:forKeys:count:]
. Since the exception message isn't shown in the crash report, and you don't provide any source code of that place we can only assume what is happening.
One assumption would be, your are creating a dictionary with nil
values or keys. But without code or you actually debugging this, this is only an assumption.
