Parse for iOS：尝试运行应用程序时出错 [英] Parse for iOS: Errors when trying to run the app

问题描述

我一直在使用Parse SDK，我遵循了快速指南。当我尝试运行时，我得到了这8个错误。任何想法为什么？它看起来与我不使用的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.

推荐答案

这是一种与Parse iOS 1.1.33版本相关的错误，因为多人看到了相同的错误 - 包括我自己。

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.

有几种解决方法 -

There are a couple of workarounds-

如果您没有使用需要-ObjC链接器标志的库，则可以从项目中删除-ObjC：

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

构建设置>其他链接器标志>删除-ObjC

Build Settings > Other Linker Flags > remove -ObjC

或者如果您使用的是需要该标志的库，则可以添加Facebook SDK。

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

这两个选项都可以消除错误。希望他们解决这个问题，因为我不需要在我的应用程序中使用Facebook SDK。

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