需求：项目需要把玩家截图上传到CDN，以后玩家能随时看见自己DIY的图。
安卓3天搞定代码，不懂OC语法，磕磕碰碰摸索了2周的时间才写完了iOS版本，拿去能直接用。
当然前提是需要按照腾讯云官网链接接入SDK文档：https://cloud.tencent.com/document/product/436/11280

我用的是手动集成。

自己弄了2个OC文件。

调用比较简单的噢，需要注意的就是，在刚进游戏的时候需要调用一下注册函数txYunRegister。

QCloudCOSXMLDemo* demo;
void txYunRegister()
{
    demo = [QCloudCOSXMLDemo new];
    [demo registerCustomService];
}
void upLoadPicTxYun(char *resPath,char *cosPath)
{
    NSString *resPatht = [NSString stringWithUTF8String:resPath];
    NSString *cosPatht = [NSString stringWithUTF8String:cosPath];
    [demo putObject:resPatht cosStr:cosPatht];
}
void searchPicTxYun(char *cosPath)
{
    NSString *cosPatht = [NSString stringWithUTF8String:cosPath];
    [demo headerObject:cosPatht];
}

安卓如果遇到困难也可私信我。
