如何从objective-c调用cocos2d-js方法

Question

我使用的是cocos2d-js，这是一个购买中的应用，当购买成功时，我需要通知消息给cocos2d-js来更新ui或其他东西。

我知道从cocos2d-js调用objective-c是这样的:在js中：

jsb.reflection.callStaticMethod("objective-cClass","methodName:", "parm");

但是，如何从objective-c调用cocos2d-js ...

Answer 1

我们知道，objective-c可以很容易地调用c++方法，所以我们可以像这样使用：

jsval ret;
ScriptingCore::getInstance()->evalString("CommonFun.setDiamond(88)", &ret);

别忘了包括头文件，对于cocos2d-x 3.8：

#include "cocos/scripting/js-bindings/manual/ScriptingCore.h"

1: js如何像这样调用objc方法，js只调用静态方法

(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调用js方法

(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);
}
