objective-c - 向 XCode 5 项目添加测试时出现问题

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，但出现以下错误。看起来它正在向我引入 OS X 库，但我不知道为什么......

关于如何解决这个问题有什么想法吗？

根据阅读“我决定是时候编写一些测试了”，我猜您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build设置下的库列表。将 SenTestingKit.framework 替换为 XCTest.framework。
