我在我的应用程序中使用 DropBox Core API，因此，我必须包含 XCTest 框架，因为当我没有添加 XCTest 框架时，我的应用程序无法连接到 Dropbox，但是当我添加框架，在为模拟器构建时出现错误。我的代码没有任何问题!这是错误:

我该怎么办？如果我的框架损坏了，你能告诉我如何重新安装它吗？我试过删除并重新安装 Xcode，但没有成功。

最佳答案

我同意迈克·韦勒的观点。您可能不应该在您的实际应用程序代码中链接 XCTest 框架。删除 XCTest 框架。查看链接器错误并删除引用框架的内容。清洗，冲洗，重复。

如果你有一个测试目标，那就不同了。在从 SenTestKit 迁移到 XCTest 的过程中很容易发生的情况是框架搜索路径错误，这会导致链接到 Mac OS X 框架而不是 iOS 框架。这行不通。

查看正确的框架搜索路径设置的简单方法是创建一个虚拟项目，打开测试目标的build设置，然后过滤“框架搜索路径”。

我认为正确的原版路径是:

$(SDKROOT)/Developer/Library/Frameworks     (non-recursive)
$(inherited)                                (non-recursive)
$(DEVELOPER_FRAMEWORKS_DIR)                 (non-recursive)
