解析 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，并遵循了快速步骤指南.当我尝试运行时，出现这 8 个错误.关于为什么的任何想法?它看起来与我没有使用的 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.

推荐答案

这是与 Parse iOS 1.1.33 版本相关的某种错误，因为很多人都看到了同样的错误——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-

如果您不使用需要 -ObjC 链接器标志的库，您可以从项目中删除 -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

或者如果您正在使用需要该标志的库，您可以添加 Facebook SDK.

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

这两个选项都会消除错误.希望他们能解决这个问题，因为我的应用中不需要 Facebook SDK.

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