之前我曾在一个在Xcode 5.1.1版本中正常运行的项目上工作过.当我使用iPhone5(8.0)模拟器在Xcode 6中运行相同的代码时,它显示了clang错误.我在这里添加错误.请帮帮我.

    ld: -pie can only be used when targeting iOS 4.2 or later
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

您的部署目标设置为 4.0，但 -pie 只能在面向 iOS 4.2 或更高版本时使用，如上面的错误消息所明确指出的。尝试将部署目标设置为 4.3。这是 Xcode 6 支持的最低部署目标。
