在向XCode 5项目添加测试时会产生麻烦

Question

我决定是时候为我的iPhone应用程序编写一些测试了。不幸的是，这并不顺利。我创建了一个新的测试类但是得到了下面的错误。看起来它正在向我提供OS X库但我不知道为什么......

此处是我的“框架搜索路径”设置的屏幕截图：

关于如何解决这个问题的任何想法？

Answer 1

从阅读“我决定是时候写一些测试了”，我猜你自创建项目已经有一段时间了。所以也许......

• 您使用Xcode 4创建了项目。测试目标将使用SenTestingKit。
• 您使用Xcode 5添加了IsoDateTest.m。最新的文件模板使用XCTest。

检查测试目标的构建设置下的库列表。用XCTest.framework替换SenTestingKit.framework。

Answer 2

升级到XCTest之后我遇到了类似的问题，我做的第一件事就是确保我的框架搜索路径都没有引用转义。他们确实没有，但我继续得到编译错误。在查看实际的编译命令之后，我注意到 仍然无缘无故地转义引号，从而导致我的Frameworks目录路径无效。

我愤怒地回到了项目设置，并确认没有报价被转义，但决定删除＆＃34; $（SDKROOT）＆＃34;周围的报价。等等。

产品 - ＆gt;清洁 产品 - ＆gt;测试

首先尝试，希望这有助于某人！

Answer 3

按照this answer删除目标框架设置中的反斜杠对我来说很有用。
