我正在阅读2个csv文件:store_inventory&new_acquisitions.
我希望能够比较store_inventorycsv文件new_acquisitions.1)如果项目名称匹配,则只更新store_inventory中的数量.2)如果new_acquisitions有一个不存在的新项目store_inventory,则将其添加到store_inventory.
这是我到目前为止所做的,但不是很好.我添加了评论,我需要添加1和2.
任何做上述任务的建议或代码都会很棒!谢谢.

无效的代码签名权利。您的应用程序包的签名包含 iOS 不支持的代码签名权利。具体而言,价值**********.com.DevName.YConvert关键application-identifier在Payload/YConvert+.app/YConvert+不支持。这个值应该是一个带有你的字符串TEAMID,后跟一个点.,然后是包标识符。
可执行文件Payload/YConvert+.app/YConvery+ i Payload/YConvert与包标识符不匹配com.DevName.YConvert-。
CFBundleExecutable在info.plist文件中,可能不包含任何这些字符:\ [] {} () .+*
我在 OS X 10.9 上使用 Xcode 5 请帮忙!
ASP.NET/MVC技术的现状是什么?是否会有影响每个代码库的重大变化?它是否稳定(向后兼容)足以在现实世界中使用?
最好的祝福
