如何在cocos2d-iphone jsbindings中将值传递给js？

Question

I'm cooking a cocos2d-iphone(v2.1) project with jsbindings. The cocos2d view running main.js in my UIKit view works properly. Now I want to add a new feature to show different animation by user input.

I want to know how to pass values to the js file in objective-c.

Thanks in advanced.

I think I found a solution.

In jsb_core.h , there is a method called: -(BOOL) evalString:(NSString*)string outVal:(jsval*)outVal; . With this method, I can call functions in my main.js from my objective-c code.

So I defined a function in my main.js file:

function test(values) {
  cc.log(values);
}

Then I can call it from my objective-c code like this:

CCDirectorIOS *director = (CCDirectorIOS *)[CCDirector sharedDirector];
if(director.runningScene) {
  [[JSBCore sharedInstance] evalString:@"test('ValueToPass');" outVal:nil];
}
