解析iOS：尝试运行应用程序时发生错误(Parse for iOS: Errors when trying to run the app)

我一直在使用Parse SDK，我按照快速指南。 当我尝试运行，我得到这8个错误。 任何想法为什么？ 它看起来像与我没有使用的Parse的Facebook部分有关。

I've been working with the Parse SDK and I followed the quickstep guide. When I try to run, I get these 8 errors. Any ideas as to why? It looks like something to do with the Facebook part of Parse which I'm not using.

最满意答案

这是与Parse iOS 1.1.33版本相关的某种错误，因为多个人看到相同的错误 - 包括我自己。

有几个解决方法 -

如果您不使用需要-ObjC链接器标志的库，则可以从项目中删除-ObjC：

构建设置>其他链接器标志>删除-ObjC

或者如果您正在使用需要该标志的库，则可以添加Facebook SDK。

这两个选项都将消除错误。 希望他们解决这个问题，因为我的应用程序中没有必要使用Facebook SDK。

按照这里的讨论：

This is some sort of bug associated with the Parse iOS 1.1.33 release as multiple people are seeing the same errors- myself included.

There are a couple of workarounds-

If you're not using a library which requires the -ObjC linker flag, you can remove -ObjC from your project:

Build Settings > Other Linker Flags > remove -ObjC

or if you are using a library which requires that flag, you can add the Facebook SDK.

Both options will eliminate the errors. Hopefully they fix this as I have no need for the Facebook SDK in my app.
