Mach-O-Linker错误消息

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需要仅链接到项目中的单元测试目标.它不应该添加到UI应用程序目标.

当添加什么我发现是XCTest.frameworkXcode中增加了额外的\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,选项卡构建设置 - >部分搜索路径 - > 框架搜索路径并编辑以删除\显示路径.

希望有所帮助!
