I have install sdkbox and iap plugins, but I dont know how I integrate to my project. I have try like no ads example in video but when I add sdkbox::IAPListener my CREATE_FUNC gives error (Allocating an object of abstract class type ‘GameScene’)
you need or override the functions sdkbox::IAPListener needs.
There is extra stuff here, but:
class HelloWorld : public cocos2d::Layer, public sdkbox::IAPListener
{
public:
// there's no 'id' in cpp, so we recommend returning the class instance pointer
static cocos2d::Scene* createScene();
// Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
virtual bool init();
// a selector callback
void menuCloseCallback(cocos2d::Ref* pSender);
void onShowAds(cocos2d::Ref* sender);
void onRequestIAP(cocos2d::Ref* sender);
void onRestoreIAP(cocos2d::Ref* sender);
void onIAP(cocos2d::Ref* sender);
// implement the "static create()" method manually
CREATE_FUNC(HelloWorld);
private:
void updateIAP(const std::vector<sdkbox::Product>& products);

Can I find simple no_ads example project in github?
sorry, no_ads example?
You mean, how to remove ads by making an IAP?
Maybe there are enough pieces here to help:

Thank you so much 
sure, if you need anything else, please let me know.
I have two button, I dont understand how it works onIAP? I didnt write ‘onIAP’ func. I set other things and now when I click to my remove ads button console says this Purchase Failed: Invalid product please double check the product id on itunes connect, It is normal or? I am sorry this is my first IAP experience.
void NoAds( cocos2d::Ref *sender )
{
sdkbox::IAP::purchase("remove_ads");
}
void RestorePurchases( cocos2d::Ref *sender )
{
sdkbox::IAP::restore();
}have you defined your items in the iTunes Connect interface?
Have I publish first version of game for in app items submit? ITunesconnect says: Your first In-App Purchase must be submitted with a new app version. Select it from the app’s In-App Purchases section and click Submit. By the way, Can you explain to me how it works onIAP function in your codes. I didnt use onIAP, do I need to use it?
You don’t have to submit your IAP, you can still test it. All you need is create a tester user in your iTunesConnect account.
How do I check remove_ads purchased?
void GameScene::ShowAds()
{
if(adsremoved)//Here how can i check?
{
CCLOG("Dont show ads");
}
else
{
CCLOG("Show Ads");
}
}
and can you explain how works this function, I dont write this func in my project, I have to?
void HelloWorld::onIAP(cocos2d::Ref *sender)
{
auto btn = static_cast<Node*>(sender);
sdkbox::Product* p = (sdkbox::Product*)btn->getUserData();
CCLOG("Start IAP %s", p->name.c_str());
sdkbox::IAP::purchase(p->name);
}Hi,
Review this: http://sdkbox-doc.github.io/en/plugins/iap/v3-cpp/
onIAP() is not part of the listener. it is just what is run when you press the button in the example. So maybe you have a Buy button and you run this when it is pressed.
As far as how to check for removing ads, I think that there are a lot of ways you can accomplish this. Perhaps UserDefaults, perhaps SQLite, perhaps even checking restored purchases.

I still have the same problem (Invalid product). How much time did you have to wait for Itunes Connect recognize your Product ID?
Hi I am also running into the error with the “Allocating an object of abstract class type ‘HelloWorld’”.
I actually copied and pasted the code that you said would have all the overridden functions that are needed, but for some reason I still get the error.
Can you show me so I can see what is happening exactly? Maybe a screenshot at least?
Can you confirm what cocos2d-x version, iOS or android, iOS or android version, sdkbox version, please.
I’m using cocos2d-x 3.7.1 on iOS. SDKBOX v0.5.6.20 and sdkbox-iap_v1.2.3.3.
Is it possible that I messed up the installation? I used the automatic sdkbox installer. And then afterwards I used the cocos command to create a project. And then I went into the project directory and typed “sdkbox import iap” into the terminal. The terminal said the installation was successful. Is there anything else that I may have missed?
I bet that if you look you are missing a function in your private section of your header or also, you don’t have all of these functions defined in your .cpp. Double check.
Add this new function please
https://github.com/darkdukey/sdkbox-iap-sample/blob/master/cpp/Classes/HelloWorldScene.h#L43
I was missing
virtual void onInitialized(bool ok);
and
virtual void onRestoreComplete(bool ok, const std::string &msg);
Thanks everyone
DJEclipse: Yes, I was missing that too. Why? Well, I guess we both read carefully the docs: http://sdkbox-doc.github.io/en/plugins/iap/v3-cpp/#usage
And, those docs make no reference at all to those 2 functions (onInitialized & onRestoreComplete). Without those functions, the build in Xcode fails. Adding those? It works.
So, hey COCOS SDKBOX folks: Please update the docs to include all functions needed for a clean build! Thanks so much for your continued great support!
