Mach-O-Linker错误信息

Mach-O-Linker error message

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) "

推荐答案

XCTest.framework 只需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。

XCTest.framework needs to be linked only to the unit test target in your project. It should not be added to the UI application target.

我发现的是添加 XCTest.framework Xcode增加了额外的 \ 到框架搜索路径

What I have found is when adding XCTest.framework Xcode adds extra \ to Framework Search Paths

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

这导致链接器问题，

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Pat hs 并编辑以删除 \ 显示路径。

To resolve this issue in XCode 5.1 goto the main ProjectWindow, Tab Build Settings -> Section Search Path -> Framework Search Paths and edit to remove \ appearing the paths.
