NSString *js = @" $('meta[name=description]').remove(); $('head').append( '' );";

WKUserScript *script = [[WKUserScript alloc] initWithSource:js injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:NO];

NSMutableString *javascript = [NSMutableString string]; [javascript appendString:@"document.documentElement.style.webkitTouchCallout='none';"];//禁止长按

WKUserScript *noneSelectScript = [[WKUserScript alloc] initWithSource:javascript injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:YES];

[userController addUserScript:script];

[userController addUserScript:noneSelectScript];

[userController addScriptMessageHandler:self name:@"openInfo"];
