Answer 1

May it help someone, as we know, objective-c can easily call c++ methods, so we can use like this:
jsval ret;
ScriptingCore::getInstance()->evalString("CommonFun.setDiamond(88)", &ret);
and dont forget include head file, for cocos2d-x 3.8:
#include "cocos/scripting/js-bindings/manual/ScriptingCore.h"

Answer 2

1:how js call objc methods like this, js call only static method
(1)//NativeOcClass.mm filename
import <Foundation/Foundation.h>
#interface NativeOcClass : NSObject
+(BOOL)callNativeUIWithTitle:(NSString *) title andContent:(NSString *)content;
#end
#implement NativeOcClass
+(BOOL)callNativeUIWithTitle:(NSString *) title andContent:(NSString *)content{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title message:content delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
[alertView show];
return true;
}
#end
(2)for js file
var ret = jsb.reflection.callStaticMethod("NativeOcClass",
"callNativeUIWithTitle:andContent:",
"cocos2d-js",
"Yes! you call a Native UI from Reflection");
2:objc call js method
(1)js method,e.g.//Test.js
var Test={
myMethod:function(){
console.log("call js");
}
}
(2)objc //filename.mm
#include "cocos/scripting/js-bindings/manual/ScriptingCore.h"
....
-(void)callJsMethod
{
jsval ret;
ScriptingCore::getInstance()->evalString("Test.myMethod()", &ret);
}
