[cocos2dx 3.0 + ios]如何编写iAd的plugin

cocos2dx3.0自带的plugin包含推广,收益等各个方面的第三方插件,但是对iAd没有支持,大概是因为专属于IOS,没有单独成库的必要,不过为了统一使用广告的插件化管理,封装一个专属IOS的IAD插件还是有必要的,搞了一天,在这里做个记录,有兴趣的朋友可以参考一下,不完善的地方请指出:

1:如何创建XCODE库就不说了,创建在其他广告库的同级目录,文件结构也是一样,一共就三个文件:

　　.pch

　　AdsApple.h

　　AdsApple.m

2:要加入到cocos2dx的PluginManager统一管理,那么我们这个新的类需要继承InterfaceAds,并且链接iAd.framework.

3:快1点了,直接上代码,完整注释:

　　头文件:

　4:使用的时候和其他的插件一样,加载,显示,隐藏,卸载..

    #if CC_TARGET_PLATFORM == CC_PLATFORM_IOS
    m_pNowAdsPtl = dynamic_cast<ProtocolAds*>(PluginManager::getInstance()->loadPlugin( "AdsApple" ) );
    if( m_pNowAdsPtl ) {
        m_mapAdsInfo["AppleType"] = "1";
        m_bUsingIAD = true;
    }
    #endif

　5:iAd有广告点击切换前后的事件通知,为了保证监听接口不变,GetPoint成了点击广告后的监听回调,用于给小费...

　6:iAd在部分国家没有支持,可以根据时区或者其他的检测方法进行广告平台之间的切换,我用的是失败次数检测,这里就不写出来了,各有各的办法.
