Mach-O-Linker 错误信息

building for iOS Simulator, but linking against dylib built for MacOSX file '/Applications/Xcode.app/Contents/Developer/Library/Frameworks/XCTest.framework/‌​XCTest' for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) "

Answer 1

XCTest.framework 只需链接到项目中的单元测试目标。它不应添加到 UI 应用程序目标。

我发现在添加 XCTest.framework 时，Xcode 添加了额外的 \ 到 Framework Search Paths

\"$(SDKROOT)/Developer/Library/Frameworks\"
\"$(DEVELOPER_LIBRARY_DIR)/Frameworks\"
$(DEVELOPER_FRAMEWORKS_DIR)

这会导致链接器问题，

ld: building for iOS Simulator, but linking against dylib built for MacOSX file '/Applications/Xcode.app/Contents/Developer/Library/Frameworks/XCTest.framework/XCTest' for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

要在 XCode 5.1 中解决此问题，请转到主 ProjectWindow，Tab Build Settings -> Section Search Path -> Framework Search Paths 和编辑以删除出现路径的 \ 。

希望对您有所帮助!
